B&T USW Conversion Kit for Glock G20/G21 Pistols


The B&T USW-G20/G21 conversion kit is the ultimate add on for the Glock 20 and 21 pistols. It offers the operator the choice of using the pistol in the traditional manner as well as with the built in folding stock, while the transition only requires less than a mere second. The operator can use an optionally available red dot sight and the original open sights as back up.

The B&T USW-G20/G21 Universal Service Weapon Chassis converts your Glock pistol into the Universal Service Weapon configuration. The USW is the size of a normal duty pistol but extends the range, accuracy and effectiveness of your handgun to that of a 9mm submachine gun. It is ideal for any situation where the chance for a longer distance shot is possible.

This configuration will enable the operator to effectively and accurately engage targets out to 50 yards and beyond; that is more than double the effective range of a service pistol. Distances that were thought to be impossible with a standard handgun. There are no modifications needed to the weapon. The whole installation takes about a minute. The USW Upgrade Chassis has an integrated standard Picatinny accessory rail for a light/laser and the folding stock. It is still ambidextrous in handling, with the ambidextrous slide catch lever and reversible magazine catch. The folding stock folds onto the right side of the weapon, where the stock release is also situated. The stock can easily and safely be operated with either the left or the right hand.

The USW Upgrade Chassis is not a firearm and thus is not serialized and can be sold and shipped with no restrictions.

The USW will enable the shooter to produce very tight shot groups at 25 yards and to place first round incapacitating hits at distances beyond 50 yards. This is possible even under the stress of a life-threatening confrontation.
