KAC Knights Armament Company SR-25 A3 6.5 CM 22" Upper Receiver 100223

The KAC SR-25 A3 complete upper receiver is chambered in 6.5 Creedmoor and built for precision long-range shooting on the SR-25/AR-10 platform. It arrives complete and drop-in ready for compatible lowers.

The 22" 4150 CMV steel barrel features a dimpled, hybrid medium profile for a strong weight-to-rigidity balance. 5R rifling with a 1:7.5" RH twist rate stabilizes heavier 6.5 Creedmoor bullets while reducing fouling and bullet deformation.

A dual-port QDC muzzle brake reduces recoil and muzzle rise for faster follow-up shots, and supports quick-attach suppressor use. The free-float M-LOK URX 6 handguard keeps the barrel isolated for accuracy and adds M-LOK slots for accessories. A full-length Picatinny top rail gives a continuous optics mounting surface with reliable zero retention.

The KAC E2 Mod 1 bolt carrier group is built for smooth, reliable cycling in 6.5 Creedmoor.
