B&T USW-G20 Conversion Kit for Glock 20/21 - Ultimate Tactical Upgrade$550.00
Availability: In Stock
Current Stock: Out of stock
The B&T USW-G17 conversion kit transforms your Glock 17 into a compact carbine without permanently altering the pistol. This is a purpose-built accessory for shooters who want the versatility of both a concealable handgun and a more stable, rifle-like platform—all from one firearm. The kit features a quick-deploy folding stock that deploys or stows in under a second, letting you transition between pistol and carbine configuration on the fly. Whether you're running drills at the range, training for home defense, or exploring precision shooting, the USW-G17 gives you flexibility without compromise.
The design accommodates backup iron sights, so you're never without a sighting solution. The conversion kit works with Glock Gen. 3, 4, and 5 models chambered in 9x19mm, .40 S&W, and .357 SIG—any Glock 17 or 19 with a standard accessory rail. The folding stock mechanism is robust and repeatable, designed for the operator who needs reliability in a modular setup.
If you're already invested in a Glock platform and want to unlock a second use case without buying an entirely new gun, this is a smart addition to your safe. The conversion preserves the pistol's original functionality while adding a carbine length sight radius and improved ergonomics when you need them. It's a practical bridge between concealable sidearm and workhorse rifle.
