Knight’s Armament 2H (HH) SR-15/16, SR-25 Heavy Carbine Buffer
KAC PN 21057
This buffer is different than your ordinary buffer in both physical appearance and construction. Instead of a traditional roll pin holding the buffer assembly together, these are built using a rivet instead. This is a much needed upgrade in durability for hard use. Finished in black anodizing.
For use in SR-15/SR-16 and SR-25 carbine platforms.

Replaced this out with my Geissele H3 buffer and I noticed a huge difference in recoil and ejection to the 3 o’clock in my 11.5 knights upper.
