LR-308 Carbine Buffer and Spring Combo

I put the Kak lr308 carbine buffer and spring combo into my 12.5” aero m5 pistol build. Haven’t had any issues with it so far. I’m running a superlative arms adjustable gas block with it and it’s been a reliable combination

KAK has excellent customer service staff. The spring and buffer work flawlessly.

Have not yet used this combo, but I'm betting once I do it will function fine. I have purchased other KAK buffer tubes, springs, and individual buffer components. I am very well satisfied with all.

I have been trying to get my DPMS LR 308 to run right for nearly a year, KAK's buffer and spring fixed it!
