Four Athlon riflescopes, all 6-24x, all first focal plane. The Argos BTR GEN3 is $537.49 MSRP. The Midas TAC GEN2 HD is $874.99. The $337.50 between them buys HD glass and cuts four ounces, and it costs you your illuminated reticle and your exposed windage turret. One rung below, the Helos BTR GEN2 at $849.99 has a bigger tube, more elevation and a locking windage turret. The Heras SPR undercuts both at $799.99 and locks its windage too.
Athlon's line names do not stack into one ladder. Focal plane, glass tier and tube diameter each move independently of price, so knowing which one you actually need is worth more than knowing which line sits higher on the website.
TL;DR: Quick Summary
Athlon riflescopes run eleven lines from $424.99 to $1,874.99 MSRP, and the line name tells you less than you think.
If you dial: Helos BTR GEN2 and Heras SPR are the two lines under $900 MSRP that give you a windage turret you can lock. The Midas TAC GEN2 dials elevation only; its windage is capped.
If you hunt and hold over: Midas HMR GEN2 and Ares HLR are second focal plane with illuminated reticles, a dialable elevation turret and windage under a cap.
If budget decides: Argos BTR GEN3 gets you first focal plane and a 30 mm tube from $537.49.
Check first: the six Argos HMR models we carry are the only 1-inch-tube Athlon riflescopes in our range. Every other line is 30 mm or 34 mm, and rings do not cross over.
Table of Contents
How to Read an Athlon Model Name
Athlon model names are dense but consistent. `Midas TAC GEN2 HD 6-24×50 APRS14 FFP MIL` breaks into six parts:
- Line. `Midas TAC`. The series, which sets the broad positioning.
- Generation. `GEN2`. Real product generations, not marketing polish. Specs change between them, so a review of a GEN1 scope may not describe the scope you are buying.
- Glass tier. `HD`. Present only on some lines. Athlon uses `HD` and `UHD` as explicit designations. A line without one is not marked down, it simply is not claimed at a tier.
- Magnification and objective. `6-24×50`.
- Reticle. `APRS14`. Athlon's reticle codes are specific patterns, and two scopes identical in every other respect can carry different ones.
- Focal plane and unit. `FFP MIL`. First or second focal plane, and whether the turrets and reticle are calibrated in milliradians or minutes of angle.
The last part is the one buyers most often skip, and it is the one that changes how the scope behaves.
How to Choose: The Three Things That Actually Change
Across the eleven lines, three specifications move, and none of them moves cleanly with price.
Focal plane does not ladder

A first focal plane reticle grows and shrinks with magnification, so its subtensions stay true at every power. A second focal plane reticle stays the same visual size, which keeps it clean at low power but means holdovers are only correct at one magnification.
Most buyers assume FFP arrives as you move up. It does not:
- Argos BTR GEN3, from $537.49 MSRP, is four of six models in first focal plane.
- Ares HLR, from $962.49 MSRP, is zero of six. Every model is second focal plane.
- Midas HMR GEN2, from $724.99, is also entirely second focal plane.
You can spend $425 more than an Argos BTR and end up in second focal plane. That is not a defect. Ares HLR is a hunting line and second focal plane is the right choice for a hunting scope. But it means "step up a line to get FFP" is simply false here, and a buyer who wants FFP has to read the model name rather than the price.
Glass wording does not ladder either
Athlon describes the glass on every model, in one of four escalating phrases: fully multi-coated, advanced fully multi-coated, HD, and UHD. The top two are part of the model name, which is why you see `Midas BTR GEN2 HD` and `Ares ETR GEN2 UHD` but plain `Helos BTR GEN2`.
Read in price order, that ladder breaks in one place worth knowing about. The $537.49 Argos BTR GEN3 is advanced fully multi-coated. The $962.49 Ares HLR, $425 dearer, is plain fully multi-coated, which is the lowest of the four steps. Paying more for an Ares HLR buys you exposed turrets, an illuminated reticle and 110 MOA of travel, and it does not buy you a higher glass claim than the cheapest 30 mm scope in the range.
Tube diameter is not a tier marker
A 34 mm tube generally allows more internal elevation travel than a 30 mm tube. Athlon uses 34 mm in Helos, Midas TAC, Ares ETR and Cronus BTR, but not consistently within any of them. The Helos line runs both: the 1-10×28 and 6-24×56 are 34 mm while the 2-12×42 and 4-20×50 are 30 mm.
So tube size tracks the individual model's intended job, not the line's rank.
Turrets and illumination are where the real trade sits

This is the split that decides day-to-day use, and it cuts across price in the most surprising way in the whole range.
| Spec | Argos BTR GEN3 6-24×50 | Heras SPR 6-24×56 | Helos BTR GEN2 6-24×56 | Midas TAC GEN2 HD 6-24×50 | What this row decides |
|---|---|---|---|---|---|
| MSRP | $537.49 | $799.99 | $849.99 | $874.99 | Budget |
| Tube diameter | 30 mm | 30 mm | 34 mm | 30 mm | Elevation headroom |
| Turrets | Exposed | Exposed elevation / locking windage | Exposed / locking | Exposed elevation / capped windage | Whether wind can drift off zero |
| Illumination | LED | LED | LED | Non-illuminated | Low-light reticle visibility |
| Total elevation | 18 MIL | 20 MIL | 29 MIL | 25 MIL | How far you can dial |
| Total windage | 18 MIL | 20 MIL | 25 MIL | 25 MIL | Wind correction in reserve |
| Weight | 30.3 oz | 32.3 oz | 34.5 oz | 26.3 oz | Carry burden |
| Glass tier | Not designated | Not designated | Not designated | HD glass | Claimed optical tier |
Read the Helos and Midas TAC columns side by side. For $25 less MSRP, the Helos gives you a 34 mm tube instead of 30 mm, 29 MIL of elevation instead of 25, a locking windage turret rather than a capped one over the same 25 MIL of travel, and an illuminated reticle where the Midas TAC 6-24×50 has none.
The Midas TAC's case is real, though, and it is two things: HD glass, which the Helos does not claim, and 26.3 ounces against the Helos's 34.5. One owner who ran both and moved from the TAC to the Helos G2 put the deciding factor on the reticle being bolder and easier to pick up at low magnification, with the TAC keeping a slight edge on glass.
That is a genuine decision, not a mistake in Athlon's pricing. If you carry the rifle a long way and value glass, the Midas TAC earns its place. If you dial wind, shoot in poor light, or want the elevation headroom, the Helos is more scope for less money.
The Compatibility Gate Nobody Mentions

Before any of the above matters, check your rings.
The six Argos HMR models we carry are the only 1-inch-tube riflescopes in our Athlon range. Every other line (Argos BTR, Helos, Midas HMR, Heras, Midas BTR, Midas TAC, Ares HLR, Ares BTR, Ares ETR and Cronus BTR) is 30 mm or 34 mm. Tube diameter is the outside diameter of the main tube where the rings clamp, and the three sizes are not interchangeable. Forcing a 30 mm tube into 1-inch rings does not work, and over-torquing to make something fit risks damaging the tube.
There is a second, sharper version of this problem inside the Argos HMR line itself. The three 4-20×50 models pair a 50 mm objective with a 1-inch tube. A 50 mm bell needs high rings to clear the barrel, and Athlon's own Precision rings are not made in a high height for 1-inch tubes. If you buy that scope, budget for third-party high 1-inch rings from the start rather than discovering the gap at the bench.
Worth noting: Athlon's broader HMR catalogue has included 30 mm models. The six we stock are all 1 inch, so verify the tube spec on the exact model you are buying rather than trusting the line name.
Line by Line, Cheapest First
Eleven lines, cheapest first. Prices below are MSRP.
Argos HMR: $424.99 to $499.99
Six models, all second focal plane, all 1-inch tube, all capped turrets. This is the entry point and the only 1-inch line we carry. Two magnification ranges, 2-12×42 and 4-20×50, with a choice of BDC, AHMC or MIL-DOT reticles and illumination on four of the six.
Buy it if: you want a capable hunting scope at the lowest entry in the range and your rifle is already set up for 1-inch rings. The 2-12×42 BDC 600 is the cheapest way in at $424.99.
Argos BTR GEN3: $537.49 to $587.49
Six models, 30 mm tube, four of them first focal plane. This is the cheapest route into FFP in the Athlon range. Note that the 1-8×24 is the outlier: second focal plane with capped turrets, and it is the one Argos BTR model without Athlon's Precision Zero Stop.
Buy it if: you want first focal plane and exposed turrets on a budget. The 6-24×50 is the one to take; the 1-8×24 is the SFP outlier.
Helos BTR GEN2: $587.49 to $849.99
Eight models, six first focal plane, and the line that punches hardest against the prices above it. Locking turrets on the 2-12×42, 4-20×50 and 6-24×56. Illumination across the whole line. The 6-24×56 and 1-10×28 carry 34 mm tubes.
The pick: if you dial, the Helos BTR GEN2 is the one we would reach for first in the whole Athlon range. The 6-24×56 gives you a 34 mm tube, 29 MIL of elevation, a locking windage turret and an illuminated reticle for $849.99, which is $25 under the Midas TAC 6-24×50 that sits above it. The exception is glass: the Helos claims no tier, and if optical quality outranks features for you, the Midas TAC is the better scope.
Midas HMR GEN2: $724.99 to $799.99
Nine models, all second focal plane, all 30 mm, all illuminated. The 4-24×50 carries HD glass; the 2-12×42 and 2.5-15×50 do not. Turrets split by magnification class: capped on the 2.5-15×50, exposed on the 2-12×42 and the 4-24×50. Elevation travel splits the same way, 120 MOA on the shorter two and 110 MOA on the 4-24×50.
The pick: for a hold-over hunting scope, the Midas HMR GEN2 2-12×42 is the one to start with. A 2x floor for close work, an illuminated SFP reticle, and 120 MOA of travel on the MOA models. Step to the 4-24×50 if you want HD glass, which is the only model in the line that carries it.
Heras SPR: $749.99 to $874.99
Six models, 30 mm, locking windage turret across the line. Two first focal plane, four second. Five of the six are 6-24×56; the outlier is a 15-60×56 SFP aimed at bench and target work.
The pick: the Heras SPR is the cheapest way into a locking windage turret in the Athlon range, and it is the only line where every model has one. Five of the six are 6-24×56, so you choose focal plane rather than magnification. The 15-60×56 is a different tool, aimed at the bench rather than the field.
Midas BTR GEN2 HD: $749.99 to $812.49
Four models, all second focal plane, all HD glass, all illuminated. The 1-6×24 pair carry capped turrets and 150 MOA of elevation, the most travel in the entire Athlon riflescope range. The 4.5-27×50 pair run exposed turrets and 85 MOA.
The pick: for HD glass in second focal plane, the 4.5-27×50 is the one to take. If it is elevation you are after, the 1-6×24 carries 150 MOA, the most travel of any Athlon riflescope, though its turrets are capped and parallax is fixed at 100 yards, so it suits a canted base more than dialing dope.
Midas TAC GEN2: $824.99 to $937.49

Six models, every one first focal plane. One of only two Athlon lines that is uniformly first focal plane, and by far the cheaper of the pair: Ares BTR GEN3 HD starts at $1,062.49. HD glass on the 4-16×44 and 6-24×50, UHD on the 5-30×56 pair, which also get a 34 mm tube and the only illuminated reticles in the line, at $937.49.
The pick: the Midas TAC GEN2 HD 6-24×50 is the one we would name for a designated glass tier with first focal plane, and at 26.3 oz it is the lightest of the 6-24x group. One condition decides it: this line has no illuminated reticle below the $937.49 5-30×56, so if you shoot in poor light, either step up to the 5-30×56 or take the Helos.
Ares HLR: $962.49 to $1,062.49
Six models, all second focal plane, all 30 mm, all illuminated, all with a graduated elevation turret and a capped windage turret. Two magnification ranges, 2.5-15×42 and 4-24×50. No HD or UHD designation. Athlon's manual describes a removable zero-stop elevation turret with no zero-stop function on the windage knob.
The pick: the Ares HLR 4-24×50 is the pick for a dial-elevation SFP hunting scope, with 110 MOA of travel and a removable zero-stop elevation turret. Windage sits under a cap on this line, so it is built to dial elevation and set wind once. Be clear about what you are paying for: Athlon claims no glass tier on this line, so the $962.49 entry buys build and turret hardware rather than better glass. If a glass tier matters more, the Midas BTR GEN2 HD carries HD from $749.99.
Ares BTR GEN3 HD: $1,062.49 to $1,124.99
Four models, all first focal plane, all HD glass, all exposed turrets, all illuminated. Two magnification ranges: 2.5-15×50 and 4.5-27×50.
The pick: the Ares BTR GEN3 HD 2.5-15×50 is the one to reach for if you want first focal plane with HD glass and exposed turrets across every model in the line. It is one of only two uniformly-FFP Athlon lines, and the dearer of the pair.
Ares ETR GEN2 UHD: $1,249.99 to $1,624.99
Five models, UHD glass throughout, locking turrets. Four first focal plane. Spans a 1-10×24 low-power variable through a 4.5-30×56 and a 15-60×56 SFP target scope.
The verdict: the Ares ETR GEN2 UHD 4.5-30×56 is the best-value UHD scope Athlon makes. At $1,624.99 it gives you UHD glass on a 34 mm tube with 32 MIL of elevation and locking turrets, which is the same glass and more windage travel than the $1,874.99 Cronus 4.5-29×56 above it. Unless you specifically want the Cronus, this is the one to buy at the top of the range.
Cronus BTR GEN2 UHD: $1,249.99 to $1,874.99

Four models and the top of the range on price. UHD glass, 34 mm tubes on the 4.5-29×56 models, 110 MOA or 32 MIL of elevation. UHD is not exclusive to this line: Ares ETR GEN2 and the Midas TAC 5-30×56 carry it too, from $937.49.
The verdict: the Cronus BTR GEN2 UHD 4.5-29×56 is Athlon's flagship and it earns the position on configuration rather than glass. UHD on a 34 mm tube with 110 MOA of elevation, in the longest-range build Athlon offers. But the Ares ETR GEN2 UHD one rung down carries the same UHD designation with locking turrets for $250 less, so buy the Cronus for the configuration, not on the assumption that it is the only way to get Athlon's best glass.
Athlon Riflescopes Compared, Line by Line
Glass tier uses Athlon's own four-step wording, taken from each model's spec sheet: Fully MC (fully multi-coated), Advanced MC (advanced fully multi-coated), HD, UHD. Athlon states a glass claim on every model, and puts HD or UHD in the model name when it applies, so a line without one is not missing information. Turret entries name the exception where a line is not uniform. Read "exposed E, capped W" literally: the elevation turret is a graduated dial you turn by hand, and the windage turret sits under a screw-off cap. Athlon's own per-model turret attribute calls that configuration Direct Dial (E), Capped (W); its one-line spec-sheet field prints only "Exposed" for it, which describes the elevation turret alone.
| Line | Models | MSRP range | Focal plane | Tube | Glass tier | Turrets | Illuminated |
|---|---|---|---|---|---|---|---|
| Argos HMR | 6 | $424.99–$499.99 | SFP only | 1 inch (25.4 mm) | Advanced MC | Capped | 4 of 6 |
| Argos BTR GEN3 | 6 | $537.49–$587.49 | 4 FFP / 2 SFP | 30 mm | Advanced MC | Exposed; 1-8×24 capped | 5 of 6 |
| Helos BTR GEN2 | 8 | $587.49–$849.99 | 6 FFP / 2 SFP | 30 and 34 mm | Advanced MC | Exposed + locking; 1-10×28 capped | All |
| Midas HMR GEN2 | 9 | $724.99–$799.99 | SFP only | 30 mm | Fully MC; HD on 4-24×50 | Exposed E, capped W; 2.5-15×50 fully capped | All |
| Heras SPR | 6 | $749.99–$874.99 | 2 FFP / 4 SFP | 30 mm | Advanced MC | Exposed E, locking W | 5 of 6 |
| Midas BTR GEN2 HD | 4 | $749.99–$812.49 | SFP only | 30 mm | HD | Capped; 4.5-27×50 exposed | All |
| Midas TAC GEN2 | 6 | $824.99–$937.49 | FFP only | 30 and 34 mm | HD; UHD on 5-30×56 | Exposed E, capped W | 2 of 6 |
| Ares HLR | 6 | $962.49–$1,062.49 | SFP only | 30 mm | Fully MC | Exposed E, capped W | All |
| Ares BTR GEN3 HD | 4 | $1,062.49–$1,124.99 | FFP only | 30 mm | HD | Exposed | All |
| Ares ETR GEN2 UHD | 5 | $1,249.99–$1,624.99 | 4 FFP / 1 SFP | 30 and 34 mm | UHD | Exposed + locking; 1-10×24 capped W | All |
| Cronus BTR GEN2 UHD | 4 | $1,249.99–$1,874.99 | 3 FFP / 1 SFP | 30 and 34 mm | UHD; HD on 1-6×24 | Exposed; 1-6×24 locking W | All |
Our Picks
| If you need… | Get this | Why | MSRP |
|---|---|---|---|
| The most scope per dollar if you dial | Helos BTR GEN2 6-24×56 | 34 mm tube, 29 MIL elevation, locking turrets and an illuminated reticle, for $25 less than the Midas TAC 6-24×50 it sits under. Not the pick if glass is your first priority | $849.99 |
| Entry into first focal plane | Argos BTR GEN3 6-24×50 | FFP, 30 mm tube and exposed turrets at the lowest MSRP in the range that offers all three. It also has the least elevation of the four scopes above, at 18 MIL, and a 6x floor | $537.49 |
| A hunting scope you hold over with | Midas HMR GEN2 2-12×42 APRS-H2 | SFP, illuminated, dialable elevation with capped windage, 35 MIL of travel, 2x floor for close work. The two MOA models in this size read 120 MOA instead | $724.99 |
| Glass tier with FFP under $900 | Midas TAC GEN2 HD 6-24×50 | HD glass with FFP, and the lightest of the 6-24x group at 26.3 oz. Skip it if you need an illuminated reticle: this line has none below the $937.49 5-30×56 | $874.99 |
| Maximum elevation in a low-power variable | Midas BTR GEN2 HD 1-6×24 ATSR16 | 150 MOA of travel, the most in the Athlon riflescope range. Turrets are capped and parallax is fixed at 100 yards, so it suits a canted base more than dialing dope. The ATSR4 twin is the only other 150 MOA model | $749.99 |
| The longest-range configuration | Cronus BTR GEN2 UHD 4.5-29×56 | UHD glass on a 34 mm tube with 32 MIL of elevation. If you want locking turrets with UHD glass, the Ares ETR GEN2 4.5-30×56 is $1,624.99 | $1,874.99 |
The Helos pick comes with a caveat worth stating plainly: if your priority is glass rather than features, the Midas TAC 6-24×50 is the better scope, and the owner who ran both says so. The Helos wins on what it gives you for the money, not on optical quality.
Frequently Asked Questions
Which Athlon riflescope line is the best?
There is no single best line, because the lines are not ranked against one another on a single axis. Cronus BTR GEN2 UHD is the most expensive and carries Athlon's UHD glass, but Helos BTR GEN2 offers locking turrets and illumination that some higher-priced lines do not, and Midas BTR GEN2 HD carries more elevation travel than anything above it. Decide on focal plane, turret type and tube diameter first, then choose the line that has all three.
Do more expensive Athlon scopes always have better glass?
No. Athlon designates glass tiers as `HD` or `UHD` on some lines and makes no tier claim on others. Midas BTR GEN2 HD carries HD glass from $749.99 MSRP, while Ares HLR at $962.49 to $1,062.49 carries no designation at all. A line without an HD or UHD marker is described by Athlon as advanced fully multi-coated, which is a coating claim rather than a glass tier.
What is the difference between FFP and SFP on an Athlon scope?
A first focal plane reticle scales with magnification so its holdover and ranging marks are accurate at any power. A second focal plane reticle stays a constant visual size, which keeps it uncluttered at low magnification but makes its subtensions correct at only one specified magnification. Athlon offers both across the range, and the choice does not track price. Argos BTR GEN3 is mostly FFP while the more expensive Ares HLR is entirely SFP.
Will 30 mm rings fit an Athlon Argos HMR?
No. The six Argos HMR models we carry have 1-inch tubes and require 1-inch rings. Every other Athlon riflescope line in our range uses a 30 mm or 34 mm tube. Check the tube diameter on the specific model before ordering rings, and note that the Argos HMR 4-20×50 pairs a 50 mm objective with that 1-inch tube, so it needs high rings that Athlon does not make in 1 inch.
Which Athlon scopes have illuminated reticles?
Most of them, but not all. Helos BTR GEN2, Midas HMR GEN2, Midas BTR GEN2 HD, Ares HLR, Ares BTR GEN3 HD, Ares ETR GEN2 UHD and Cronus BTR GEN2 UHD are illuminated across every model. Midas TAC GEN2 is the notable exception. Only the 5-30×56 UHD pair carry illumination, at $937.49; the 4-16×44 and 6-24×50 models do not offer it at all.
How much elevation travel do Athlon riflescopes have?
It ranges widely and does not follow price. The Midas BTR GEN2 HD 1-6×24 carries 150 MOA, the most in the range. Ares HLR 2.5-15×42 and Midas HMR GEN2 2.5-15×50 both carry 120 MOA. The Argos BTR GEN3 6-24×50 carries 18 MIL, and the Helos BTR GEN2 6-24×56 carries 29 MIL. Because Athlon publishes these figures per model rather than per line, check the specific model's specification rather than assuming from the series.
