With dozens of 5 star reviews from around the web, many builders have found this to be an indispensable (and cost effective) addition to their large platform AR-10 / LR-308 builds. Short barreled or suppressed 308 builds can be finicky and whether tuning the buffer system for reduced recoil or tempering an over-gassed system, this heavy buffer will do the trick. It is also build to last, machined from stainless steel right here in the USA. Using genuine Tungsten counter weights, you can be sure that this Heavy Buffer will hold up when it matters most.

USKAK LR-308 Stainless Carbine Heavy Buffer
I am a Manufacturer and this is our "go to" buffer. After building hundreds of AR 10s, some std buffers wont reliably send the bolt into battery. The KAK heavy buffer does it 100% every time. Just feel that they are way over priced and should cost half as much
USSolved over gassed issue
Had issues with my 6.5 Creedmoor gas gun , major extractor marks and flinging brass at 1, 2 o’clock . Put heavy buffer in and new spring and no marks on brass disappeared and brass flew to the 4 o’clock position.. no more concerns from me
KAK LR-308 Stainless Carbine Heavy Buffer
Purchased to help slow bolt speed on a PSA PA-10 that came with a standard weight buffer. Looks good, works fine, and the best price on the internet! Thanks AR-15 Discounts!

Works Great
I ordered this buffer to smooth out the bolt carrier cycling. The buffer and spring are working great as a set and have accomplished the intended task of smoothing out the transition. I could not be happier and would recommend to anyone wanting a heavier buffer
