Like a H3 buffer for your LR-308

This is a beautiful part. Most shorty 308 buffers weigh 3.8 oz. KAK advertises this as 5.3 oz, but mine is closer to 5.2. Still significantly heavier than a regular buffer. Helps reduce recoil and has also helped with stripping rounds out of my metal magazines that seem to have more friction than the polymer mags. A very worthwhile addition.

Excellent for reducing recoil and solving overgassing problems.


Machining and finish are impressive. This buffer works for the DPMS gas system, and will noticeably improve function. Most 7.62x51mm/ .308Win ARs are overgassed, and this buffer addresses that. Felt recoil is also reduced. I'd rate this as almost as good as the CTS AKTIVE buffer (and it is slightly cheaper than the CTS). A solid upgrade for function and reliability.
