B&T USW-G17 conversion kit for Glock 17, 19 and 23

The USW-G17 chassis is the ultimate conversion kit for the Glock 17 and 19. It allows the user to use the weapon as a pistol or with a shoulder stock, with the changeover taking only fractions of a second thanks to the quickly folding integrated shoulder stock. Due to the well-thought-out design, the user can mount an optionally available red dot sight and continue to use the original sight as a backup. The USW-G17 stock fits all Glock pistols with a standard rail (generations 3-5) in 9x19mm, .40 S&W, and .357 SIG calibers. A red dot sight (MOS) must not be mounted on the slide.
