Alpen Apex XP 2.5-16x42 A4 Riflescope with SmartDot

The Alpen Apex XP 2.5-16x42 is a premium hunting riflescope designed for day and twilight use, with SmartDot technology that automatically activates the illuminated reticle when you shoulder your rifle — no fumbling for controls, no wasted battery life, just instant readiness when every second counts.

Key Features

• SmartDot Auto-Activation — A built-in tilt sensor detects your rifle's position and activates the illuminated red dot instantly. Ten brightness levels cover daylight through deep twilight. Tilt past 50° or set the rifle aside and the reticle enters sleep mode within seconds, then wakes in milliseconds when you raise the rifle again.

• FluoDigits Zoom Display — Fluorescent magnification numbers charge in daylight and glow discreetly in low light, letting you read your zoom setting without a flashlight and without revealing your position. Provides at least 5 hours of illumination.

• UBX Fully Multi-Coated Optics — Alpen's proprietary lens coating delivers up to 95% light transmission, producing bright, high-contrast images from early dawn through last light.

• German #4 Illuminated Reticle (A4) — A clean, familiar reticle design in the second focal plane with an illuminated center dot. The SFP placement keeps the reticle size consistent across the full 2.5–16x zoom range.

• Precise MRAD Adjustments — True 0.1 MRAD elevation and windage clicks with a zero stop function for confident adjustments and blind return to zero without checking turret positions.

• Side Parallax Correction — Adjustable from 10 meters to infinity for a sharp, parallax-free image at any engagement distance.

• Built for Harsh Conditions — IPX7 waterproof and submersible to 3 meters, nitrogen-purged for fog resistance, and tested to withstand 1,000 g of recoil for magnum-caliber use.

• Compact and Lightweight — At 345 mm long and just 615 g, the short tube design is purpose-built for hunters running clip-on night vision or thermal attachments.

Ideal For

• Twilight and low-light hunters who need reliable illumination without battery anxiety — SmartDot's auto sleep/wake means the reticle is always ready when you shoulder the rifle.

• Versatile all-round hunters looking for a single scope that covers driven hunts at 2.5x through precision shots at 16x, with a 30mm tube that balances light gathering and mounting flexibility.

• Hunters using clip-on attachments — the compact 345 mm length and lightweight 615 g build leave room for night vision or thermal devices without excess weight or balance shift.

• Shooters who value intuitive operation — FluoDigits, SmartDot, and zero stop reduce the things you need to think about in the field so you can focus on the shot.
