COMPLETE BARRELED UPPER RECEIVERS

Shop our wide selection of AR-15 Complete Upper Receivers. Choose from multiple caliber upper receivers, including CMMG MK9 9mm uppers. Pistol caliber upper receivers are a great addition to your 5.56 or .223 build. Additionally, you can purchase one of our .22 LR upper receivers and simply swap out your existing upper with a dedicated 22 barrel and upper.

We also carry CMMG 308 and 300 blackout complete uppers. CMMG MK3 and MK4 uppers allow you to shoot a larger caliber from your AR15 or AR10 platform. 308 AR's are great for hunting and precision shooting.
