Heckler & Koch USP Blowback 4.5 mm BB CO₂ Windshield
H&K USP Blowback 4.5 mm BB is a pneumatic replica of the iconic German Heckler & Koch self-revolving pistol, designed for users who expect maximum realism. The model is distinguished by metal lock, robust polymer backbone and licensed manufacturer's markings.
The biggest advantage of this version is powerful Blow-Back System, which simulates the movement of the breech during firing, providing a realistic feel similar to the operation of a firearm.
Realistic design and functionality
The gun was designed with great attention to detail, maintaining the proportions and ergonomics of the flammable prototype. Proper balance and profiled handle guarantee a secure grip and high comfort of use.
Features of the Heckler & Koch USP Blowback air pistol
Very faithful reproduction of the original.
Strong Blow-Back System with a pronounced lock recoil.
Metal lock and durable polymer frame.
CO₂ power supply for self-repeat shooting.
Fully functional keypads: fuse, magazine and lock release.
Fixed aiming instruments: a bow tie and a pinniped.
Ergonomic grip for improved gun control.

Power supply CO₂
The model uses 12-gram CO₂ capsule, mounted in the magazine. One capsule allows you to cast about 50-60 shots, depending on the ambient temperature, rate of fire and technical condition of the replica.
A punctured capsule can be left in the magazine for a maximum of 48 hours. Blow-Back system provides realism at the expense of slightly higher gas consumption compared to the non-jetted version.
Targeting instruments
The gun is equipped with fixed mechanical instruments with bright dots that make it easier to quickly align the bow tie with the sights and improve the comfort of aiming under recreational conditions.
SA/DA trigger mechanism
The mechanism used DA/SA allows shooting both with a self-draw (DA) and a short, light trigger when the cock is tightened (SA).
Mode SA provides short trigger path and high precision.
Mode DA offers more resistance and a longer stroke, without the need to manually tighten the cock.
This solution combines safety with high versatility of use.
Steel BB magazine
Magazine housing 18 steel BB 4.5 mm balls is extended from the handle. The tooth on the pot facilitates quick loading. BB ammunition is ideal for recreational shooting at reactive targets, cans or bottles.
Security
The model has wing fuse, which also functions as decocker, allowing the cock to be lowered safely without firing a shot. This solution improves safety when carrying and storing the replica.
