Heckler & Koch HK45 .177 Cal GBB CO2 Air Pistol, Black

Reaching muzzle velocities up to 400 FPS with .177 caliber (4.5mm) steel BBs, the black Heckler & Koch HK45 GBB CO2 Air Pistol utilizes a high-output 12g CO2 blowback system for strong recoil and rapid cycling. Heckler & Koch built this replica with a metal slide, outer barrel, and internal mechanics over an ergonomic glass-reinforced polymer frame. Operating in semi-automatic action, it feeds reliably from a 22-round drop-free magazine. Factory box contents include the HK45 CO2 air pistol, one 22-round BB magazine, and an instruction manual.

Built with dedicated airgun valve assemblies and custom internals, this platform does not support aftermarket internal modifications. Because Heckler & Koch tuned this model for strong velocity straight from the factory, player enhancements are best centered on range accessories and maintenance. To maximize range readiness, attach a weapon light or laser to the integrated lower accessory rail, stock spare Heckler & Koch 22-round CO2 magazines, run high-grade .177 steel BBs, and apply silicone oil routinely to protect internal seals.
