The Kaw Valley Precision Stainless Steel Heavy Tungsten Buffer, 10 oz (Kaw Valley Precision part no. KVP10OZ) combines a stainless steel buffer body with internal tungsten weights to reach 10 ounces, among the heaviest standard AR15 buffer weights available, for builds that need maximum mass to tame an aggressively over-gassed system or heavily suppressed setup. Tungsten’s high density lets Kaw Valley Precision pack more weight into the same standard buffer dimensions than steel alone could achieve. This buffer is a common choice on suppressed 300 Blackout and heavily gas-tuned rifles where cycling still feels too fast or harsh even with a mid-weight buffer installed. It drops into any standard mil-spec buffer tube without modification.

Frequently Asked Questions

When would I need a 10-ounce buffer instead of a lighter option? Heavily suppressed or aggressively over-gassed builds sometimes need the extra mass of a 10-ounce buffer to smooth out an otherwise harsh cycling impulse.

Does this buffer fit a standard mil-spec buffer tube? Yes, it’s built to drop into standard mil-spec AR15 buffer tubes.
