Armaspec SMB H Gen3 Sound Mitigation Buffer, 3.8 oz., AR-15, ARM258-H

Armaspec SMB H Gen3 Sound Mitigation Buffer, 3.8 oz., AR-15, ARM258-H

This Armaspec Sound Mitigation Buffer, model ARM258-H, is a single-stage, captured buffer and spring assembly built for standard AR-15 carbine buffer systems, weighing 3.8 ounces in the H (heavy) weight class. Made in the USA, it replaces a traditional separate buffer and recoil spring with an integrated design aimed at reducing spring contact noise inside the buffer tube.

Key Features

• Single-stage, captured buffer and spring assembly
• 3.8 oz., H (heavy) weight class
• Gen 3 design
• Reduces spring contact with the buffer tube to minimize traditional buffer-spring noise
• Compatible with standard AR-15 carbine buffer systems
• Made in the USA
• Captured buffer, guide rod, recoil spring, and integrated buffer assembly included

Construction and Function

This buffer is built as a captured, linear recoil system combining a metal buffer body with polymer components, finished in black and natural metal tones. As a single-stage design, it integrates the buffer, guide rod, and recoil spring into one assembly, replacing the traditional separate buffer and spring setup. This construction is designed to reduce spring contact with the inside of the buffer tube, minimizing the noise typically associated with a standard buffer-spring assembly.

Compatibility

This buffer system is compatible with standard AR-15 carbine buffer systems as a replacement or upgrade component.
