KAK Industry LR-308 Heavy Rifle Buffer, 9.3 oz

Yeah, you kind of need this. Adjustable gas block plus this buffer will solve early bolt unlock. Pretty inexpensive upgrade considering the rifle will run so much better.

I bought this buffer because I had a gun that was running extremely hot, eating brass and sending the brass 10 yards in front of me. After putting the heavy buffer in, my brass was landing next to me. I did not have any issues with cycling, and my shoulder no longer has any bruises. I have run about 300 rounds without any issues. I don’t like adjustable gas blocks, and I would rather tune the recoil with springs and weights. This buffer did not require any weight changes and tamed a very aggressive gas system.

I bought this buffer to mitigate my AR-10’s forward ejection pattern/over gassed effect due to back pressure from shooting suppressed. The product slightly reduced the forward ejection pattern from the 11 o’clock to the 9:30 o’clock position, and the recoil pulse is less snappy and a lot more enjoyable to shoot. Unsuppressed, my rifle was ejecting at around the 7 o’clock position, so I still might try a wolf heavy rifle spring to see if I can tune it even more.

Still my goto heavy .308 / 6.5CM heavy rifle length buffer... Very effective to help slow the cyclic speed / unlocking of the bolt, combine this with a Quality Adj. GB...the KAK 9.3oz buffer is still #1 for me and my Large Frame rifle stocked AR's . Since my previous review, I have tried some of the Hydraulic buffers... and gotta say, I prefer Stoners design.. a dead blow buffer like the KAK heavy weight 9.3oz.

I have 4 of these installed in .308 and 6.5CM rifle stocked PSA PA10 Gen II's .... add a Tubbs .308 Flatwire, and a Adj GB .... and you will be AMAZED how soft shooting both of those can become. Everyone that has fired the rifles with those parts installed says about the same thing... "There is no recoil !? " Added benefits are ... much better brass life ( extraction is slightly delayed by milliseconds allowing a lower chamber pressure extraction ) , MUCH easier to stay on target... because of the less abrupt cyclic speed common in .308AR's, faster follow up shots, and just a MUCH smoother shooting Large frame AR. If you have a rifle stocked AR... in any caliber, that "kicks" harder then you like.... don't just endure it... help mitigate that recoil impulse with one of these. Again KAK offers a excellent product, and this is one I will install in all my rifle stocked Large frame AR's.

This is a very excellent buffer for custom ar10.I was having over gassed issue in my 18 inch dpms lr sass 308 rifle causing the BCG to rip off the back off ammo case and causes it to Double feed . Once I drop this buffer in it ran like a champ.

I have both an AR10, and an AR 6.5 Grendel. These rifles were both over gassed and recoiled quite abruptly even with Tubbs flatwire springs. With the addition of the KAK 9.3oz heavy rifle buffer, the abrupt recoil has stopped and both rifles are far more pleasant to shoot now. These guys have excellent customer service and will take care of the customer at any cost. Thanks KAK for such a great product at an affordable price!
