Kak Industry AR-15 K-SPEC A5 Buffer and Spring Kit 6.5 oz ODG

KAK built the K-SPEC buffer to cut felt recoil and speed up follow up shots, borrowing the idea behind modern dual spring pistol recoil systems. This kit pairs a 6.5 oz A5 length buffer with a KAK flatwire buffer spring.

The buffer uses sliding weights, two tungsten and one steel, and a red bumper. It is made to work with an A5 style buffer tube and the KAK flatwire spring, and it comes with the KAK buffer install tool.
