The Armaspec Buffer AR10 Gen3 4.7 oz Sound Mitigation system is a purpose-built replacement buffer assembly engineered to quiet your AR-10 platform rifle without sacrificing reliability or feel. Unlike standard buffers where spring coils rattle against the tube walls, this captured design isolates the spring to deliver noticeably smoother and quieter bolt cycling—a meaningful upgrade if you shoot suppressed, hunt in tight country, or simply prefer a more refined shooting experience. It's a straightforward drop-in replacement that requires no gunsmithing, making it one of the easiest ergonomic and operational upgrades you can make to an AR-10.
The key to the Gen3's noise reduction is its captured spring mechanism. By preventing the spring from contacting the buffer tube interior, Armaspec eliminates that metallic rattle that standard buffers produce on every cycle. Shooters often notice the difference immediately—especially noticeable during strings of fire or when running the rifle in quieter environments. The system also helps manage felt recoil, making follow-up shots faster and more controlled. Spring weight is adjustable, so you can fine-tune the system to your specific bolt carrier group, ammunition, and shooting style.
Made in the USA, this buffer ships complete and ready to install: you get the polymer base guide rod, spring, and the 4.7 oz buffer itself. If you're building or upgrading an AR-10 and want a noticeable step up in smoothness and a measurable drop in mechanical noise, the Armaspec Sound Mitigation buffer is worth the investment.
