Hammers 4-12x40 AO Air Gun Rifle Scope

Overview

A 4-12x40 variable power rifle scope built specifically for high-power spring and nitro-piston air rifles, with an adjustable objective, mildot reticle, and a one-piece mount that includes a built-in stop pin.

Spring and nitro-piston air rifles produce a double-direction recoil shock that breaks many scopes not built for it; this one is internally reinforced for that specific shock pattern, and the one-piece mount with four clamping screws is meant to hold alignment under it. Reviewer experience is mixed on whether the mount fully solves that problem: several report the scope holding zero fine, while others report the mount slipping on the rifle's dovetail rail or the scope losing zero after dozens of shots.

• 4-12x variable magnification, 40mm objective
• Adjustable objective and mildot reticle
• One-piece mount with 4 clamping screws and stop pin
• Reinforced for piston-type airgun recoil

Who it's for

Air rifle shooters using spring-piston or nitro-piston magnum rifles who need a scope built for that recoil pattern rather than a firearm scope repurposed for airguns. Budget-focused buyers wanting a step up from a factory-included scope.

Pros and cons

Performance notes

The internal reinforcement targets the reverse-recoil shock unique to spring and nitro-piston airguns, which is the failure point for scopes designed only for firearms. Finger-adjustable 1/4 MOA turrets and a fast-focus ring let sighting-in happen without tools. Reviewer results split on mount security: some report it surviving heavy piston shock without issue, others found the mount slipping on the dovetail groove or the turret cap coming loose from insufficient glue on the threads.
