5.56x45 C.A.P.S. Carbine Piston Upper with Troy Bravo Handguard

A: While we can remove the muzzle device from any upper order through the products page, we can't add the RM-30 Muzzle Device to the 5.56 product line of uppers as the 5.56 and the RM-30 have a different barrel threading size. The 5.56 barrels utilize a 1/2"x28" threaded muzzle device while the RM-30 muzzle device is a 5/8x24" thread for the large 30 calibers such as 7.62x39, 300BLK, .308, etc. While we do plan on doing a muzzle device for the 5.56 product line of uppers we just haven't had a chance to get to it due to other products we are trying to push out over the next couple of months, sorry!
