Licensed Colt M45A1 Combat Unit Replica - TAN [EMG]

Colt 1911 M45A1 GBB is a licensed gas-powered replica of the classic 1911 pistol, designed with a focus on realistic blowback operation, full metal construction, and tight fitment with no noticeable wobble between components. Developed in cooperation with 6mm Pro Shop, the model uses TM-compatible internal parts.

Construction and design

The replica is based on the classic Colt 1911 platform, retaining the characteristic ergonomics and control layout known from the original firearm.

The metal slide, frame, outer barrel, magazine, and external controls contribute to realistic balance and a pronounced blowback cycle. All components are precisely fitted, and the construction has no noticeable play between parts.

The model features a beavertail grip safety and a manual thumb safety, supporting safe and controlled handling.

An individual serial number is located on the trigger guard.

Internal parts and mechanics

The replica uses T8 components including the Hop-Up bucking, magazine gasket, and piston seal. These parts support gas efficiency and stable cycling performance.

The 115 mm inner barrel supports stable BB guidance during firing.

The outer barrel features an 11 mm CW internal thread, allowing the installation of compatible muzzle devices.

Gas system and hop-up

The replica is equipped with an adjustable hop-up chamber that allows the BB trajectory to be tuned for different BB weights and engagement distances. Adjustment is performed after removing the slide.

The model is compatible with both Green Gas and dedicated CO2 magazines designed for the platform.

Factory muzzle velocity reaches ~300 FPS.

Power supply

The replica is powered by Green Gas. The magazine holds 25 BBs and also stores the gas required for blowback operation.
