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.

worked perfect in my .308 build
This buffer worked GREAT in my .308 build. I matched it with a Sprinco "orange" spring and I was ejecting cases at 4 o'clock.

Works fine!
Finally got to test the product, seems to have smoothed out the cycling of the rifle a bit, the lighter buffer seemed like it was bottoming out, feels much better.

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
