S45 .45 Magazine

BinTac CNC Aluminum Magazine for BinTac and AEA S45 .45

The BinTac or AEA S45 is a powerhouse of a semi-automatic airgun, but a rifle is only as reliable as its magazine. Stock plastic magazines often introduce friction, flex, and fragility into the system—especially when using heavy, high-coefficient slugs. The BinTac S45 .45 CNC Magazine is engineered to eliminate the “weak link,” providing a feed system that matches the ruggedness of the rifle itself.

Built for Battle (and Hunting)

Precision-machined from a solid block of aerospace-grade aluminum and finished with a durable hard-anodized coating, this magazine is virtually indestructible in normal use. Where plastic feed lips wear down over time, causing jams or double-feeds, the BinTac CNC aluminum lips maintain their geometry indefinitely. This ensures that every round is presented to the chamber at the exact same angle, every time.

Optimized for Slugs

Serious big-bore shooters prefer slugs for their ballistic coefficient and down-range energy. The BinTac CNC magazine is designed with slightly wider internal tolerances to accommodate a broader range of slug shapes and lengths that often bind in factory magazines. The internal spring tension is calibrated to keep up with the S45’s rapid semi-auto cycle rate without crushing softer lead skirts.

Key Features

• Zero Flex: The rigid aluminum body prevents the magazine from expanding under spring pressure, ensuring a smooth drop-free fit in the mag well.
• Smoother Cycling: Polished internal surfaces reduce friction, allowing the rotor to spin freely for lightning-fast follow-up shots.
• Tactical Aesthetics: The matte black anodized finish perfectly matches the tactical look of the S45 platform.
