Imported from the Czech Republic as a pistol, this Bren with its 11″ barrel has proven a popular SBR candidate for customers wanting to convert it to an NFA firearm. Those who don’t wish to register with the ATF can always equip it with CZ's adapter kit (sold separately) that allows easy installation of aftermarket arm braces or other devices meant to help stabilize large format pistols like this. Chambered in .223/5.56mm and using the ubiquitous STANAG magazine from the AR15/M16, it easily accepts optics and lights on its top and bottom Picatinny rails. An effective two-port muzzle brake helps keep the pistol solidly on target and reduces recoil and muzzle flip. The cold hammer forged barrel has 1/2x28 muzzle threads. Back-up sights are included, with two interchangeable rear aperture sizes.
