Product Summary
The Armaspec Gen 3 SMB is a single-stage, captured drop-in replacement for standard AR-15 carbine buffer and spring assemblies. It is specifically engineered to prevent the buffer spring from rubbing against the inner wall of the buffer tube, ensuring smoother and quieter operation. This kit helps reduce felt recoil while offering an adjustable spring weight for customized performance. Users can trim the main spring at .25 lbs per coil, up to a maximum of 12 coils, to fine-tune tension. It is an ideal upgrade for shooters looking to improve the cycling feel and noise profile of their carbine.
