KAC-Knight’s Armament SR-16 Mod 2.1 Upper Receiver/Suppressor Package (124428)

First commercial release of the 11.5″ SR-16 Mod 2.1 upper receiver kit!

The 10.75 KAC FF RAS 5 handguard was developed for use on SR-16 platforms, specifically optimized for KAC upper receivers with a notched receiver.

The enhanced barrel nut interface and robust construction keep deflection minimal while enabling user-level barrel replacement.

The full-sized Combat Rifle Suppressor (CRS2) was designed to virtually eliminate flash and system backpressure while exceeding the durability that KAC signature reduction.

Pressure Reduction Technology minimizes back pressure, resulting in a negligible gas increase in the system that is typically responsible for bolt carrier velocity and rate-of-fire acceleration
