Kite Optics B6 LR 3-18x50 Riflescope (4Ai Reticle)

The Kite Optics B6 LR 3-18x50 with 4Ai reticle is the long-range specialist of the B6 LR family — pairing 3–18x magnification and a large 50mm objective with side-focus parallax adjustment and a ballistic turret system featuring integrated zero-stop. The classic 4Ai illuminated reticle delivers a clean European sight picture for precision hunting at distance.

Key Features

• 3–18x magnification with 6x zoom ratio — Enough low-end at 3x for woodland and medium-range work, with 18x at the top for precise shot placement and target identification at extended range. The 6x zoom ratio covers the full spectrum from 200-yard timber shots to 600+ yard open-country work.

• 50mm objective with 90% light transmission — The larger objective lens gathers significantly more light than the 42mm model, delivering a brighter image at higher magnifications and extending usable shooting time deeper into dawn and dusk. MHR Advance coatings maximize light throughput across all surfaces.

• Side-focus parallax adjustment (100m to infinity) — A dedicated parallax ring on the left side of the turret housing allows precise parallax elimination at any distance from 100 meters outward — essential for accurate shooting at the magnifications this scope delivers. Engraved in both meters and yards.

• 4Ai illuminated reticle (SFP) — The refined German No. 4 pattern with thick outer posts tapering to a clean center area and a floating illuminated red dot. 11 brightness levels plus daylight boost. The classic hunting sight picture that European shooters have trusted for generations, with modern illumination for low-light precision.

• Ballistic turret with zero-stop and revolution counter — Exposed elevation turret with positive 0.25 MOA clicks, integrated zero-stop, and pop-up revolution indicator for tracking adjustments across multiple turns. Push down to lock and prevent field bumps.

• 90 MOA total adjustment range — Designed around the longer-range shooting this scope enables, with each click at 0.7 cm per 100 meters providing fine control.

• 100mm eye relief — The most generous eye relief in the B6 LR range, providing safe, comfortable shooting with heavy-recoiling magnum calibers.

• One-piece 30mm aluminum tube, IPX7 waterproof — Machined from solid aluminum, nitrogen-purged, and submersible to 1 meter. Operating range from -20°C to +71°C.

• 750g with included zoom throw lever — Substantial enough to handle recoil, with a snap-on throw lever for rapid magnification changes.

Ideal For

Long-range hunters who glass and shoot at distance — mountain hunters, open-country western hunters, and anyone whose typical shooting extends past 400 yards. The 3–18x range, side-focus parallax, and zero-stop turret are built for this discipline.

European stalking hunters who want the extended reach of 18x with the familiar 4Ai sight picture. The classic reticle and illuminated center dot provide the clean aiming point that driven and stalking hunters prefer.

Low-light specialists who take shots at dawn and dusk. The 50mm objective and 90% light transmission deliver meaningful brightness advantage over 42mm scopes when legal shooting light is fading.
