(10 customer reviews)


29 in stock (can be backordered)



These barrels are properly stress relieved after rifling, air-gauge tested, and individually checked for headspace. 0ur quality control system ensures they are dimensionally correct and bores fall well within their individual tolerance ensuring superior accuracy. This barrel is designed to fit a 15″ handguard (our BKF, Mod-0 and Mod 1 handguards are the perfect compliment) with minimal gap between the handguard and a suppressor.

    Make sure you keep these in stock for the coming months. I’m currently developing a G36 style 9mm and this is one of the chosen barrels. Just don’t go changing any dimensions on me.

    Major, major issues with feeding even 115 gf ball ammo. 147 gr? Forget it.
