Every AR-15 owner is familiar with that iconic spring noise—the "twang" or "crunch" from the buffer spring scraping and vibrating inside the buffer tube after every shot. The Armaspec SMB™ (Sound Mitigation Buffer™) Gen3 is the ultimate solution engineered to completely solve this problem, not only eliminating the noise but also significantly enhancing the overall operational quality of your AR-15.
This product is the perfect embodiment of Armaspec's engineering innovation. It integrates the traditional separate buffer and spring into a single, self-contained, captured guide rod system, providing an immediate and impactful core upgrade for your firearm.
Key Features:
Signature Silent Experience: Its core single-stage captured design keeps the buffer spring on the guide rod during its travel, completely eliminating contact and friction with the inner wall of the buffer tube. The result: the annoying spring noise is completely gone, and every cycle of the action becomes unbelievably smooth and quiet.
Reduced Recoil, Improved Control: The precision-engineered design of the SMB™ helps to more effectively manage the kinetic energy of the Bolt Carrier Group (BCG). This not only stabilizes the action but also effectively reduces felt recoil and muzzle rise, making your rapid follow-up shots more stable and accurate.
Easy "Drop-in" Installation: The upgrade process is extremely simple. Just like removing your factory parts, place the entire SMB™ Gen3 unit into your carbine-length, Mil-Spec buffer tube. No special tools or modifications are needed. It is a true "plug-and-play" upgrade.
Multiple Weight Options for Fine-Tuning: Offering various weight options from standard Carbine (C) to H, and H2, allowing you to fine-tune your AR for your specific setup—considering barrel length, gas system configuration, suppressor use, or ammunition type—to achieve the most ideal ejection and operational status.
Made in the USA, Quality Guaranteed: Upholding Armaspec's consistent high standards, the SMB™ Gen3 is entirely designed and manufactured in the USA, ensuring the best material quality and durability you can trust.
