The Kaw Valley Precision AR-10 Carbine Stainless Steel Tungsten Buffer, 5.6 oz (Kaw Valley Precision part no. KVPAR1056) is sized specifically for AR-10-pattern .308 carbines, combining a stainless steel body with internal tungsten weights to add reciprocating mass in a buffer length built for the larger AR-10 platform. The added weight helps smooth cycling on AR-10 builds running a suppressor or an aggressively tuned gas system, where the heavier 7.62×51 bolt carrier can otherwise cycle harshly. Because AR-10 buffers use different length and diameter standards than AR15 buffers, this part is built to the correct AR-10 carbine specification rather than a scaled-down AR15 buffer. It’s a direct swap into a compatible AR-10 carbine buffer tube.

Key Specifications

• Weighs 5.6 ounces, adding reciprocating mass sized for AR-10 carbine systems.
• Combines a stainless steel body with internal tungsten weights for added density.
• Built to AR-10 carbine buffer dimensions, not the AR15 standard.
• Drops into a compatible AR-10 carbine buffer tube without modification.
• Sold as a single buffer, not a complete buffer system kit.

Frequently Asked Questions

Will an AR15 buffer work in my AR-10 instead of this one? No, AR-10 platforms use different buffer length and diameter standards than AR15, so a correctly sized AR-10 buffer like this one is needed.

When is added buffer weight most useful on an AR-10? Suppressed or aggressively gas-tuned AR-10 carbines often benefit most from the extra mass to smooth cycling.
