*Many aftermarket drop-in triggers use modified hammers and can be temperamental in Blowback systems. For the most consistent results a Mil-Spec fire control group is recommended. However, in our testing, these aftermarket fire control groups should work in most circumstances: POF, Hiperfire EDT and 24 series, Geissele, Timney, Rock River, and Spike’s Tactical.
No doubt, a .45 caliber AR-15 blowback design pistol or carbine is a lot of fun to shoot. However, those little rounds are pretty tough on the internal components of your AR-15, add a suppressor and things get even harder. That doesn't mean you forget it and stay with a full-size weapon, you just need to bring the right parts to the game.

When you place a high-quality Kaw Valley .45 ACP bolt carrier group in the heart of your AR, your gun will run and you can fight.
