The Armaspec SMB Gen 3 is a sound mitigation buffer assembly built to replace your AR-15's stock buffer and spring with a single-stage captured system that actually works. If you've felt excessive felt recoil or heard that metallic rattle of a spring bouncing inside the tube, this is the fix. By preventing the buffer spring from contacting the inner wall of the buffer tube, the Gen 3 delivers noticeably smoother and quieter cycling—whether you're at the range, hunting, or running drills. It's a straightforward drop-in replacement that requires no permanent modifications to your carbine.
The system ships complete: you get the polymer base guide rod, the spring, and the buffer itself—everything needed to install and shoot. Armaspec engineered this for the H2 weight class (5.81 oz total), a balanced choice for most AR-15 carbine builds. The single-stage design with captured components means no loose parts rattling around, and the adjustable spring weight lets you tune recoil feel if you run different ammunition or barrel lengths. Made in the U.S.A., it's the kind of upgrade that makes a real difference in shooter comfort and firearm reliability over time.

Yes. The Gen 3 replaces your standard buffer and spring as a complete captured system. No modifications to your receiver or buffer tube are required—it installs like any standard buffer assembly.
The package includes the polymer base guide rod, the spring, and the buffer. It's a complete system ready to install.
The spring weight is adjustable, which allows you to tune the recoil impulse to match your ammunition type, barrel length, and shooting preferences.
The primary benefit is isolation of the spring from the buffer tube wall, which eliminates the metallic rattle and creates smoother, quieter cycling. Sound reduction is internal—the gunshot itself won't be quieter.
