Foxtrot Mike Products Mike-15 RMB AR-15 Heavy Buffer - Carbine

The Foxtrot Mike Mike-15 RMB (Recoil Mitigating Buffer) trades the usual brute-force approach to taming bolt bounce for a more refined internal design, giving Mike-15 owners a genuinely smoother-cycling upgrade over a standard solid buffer. Built with a sliding outer body and precision-balanced reciprocating mass, this AR-15 buffer absorbs and dissipates recoil energy through the cycle rather than relying on raw mass alone.

Features:

• 5 oz weight
• A5 length
• Precision-balanced internal reciprocating mass
• Sliding outer buffer body
• Integrated dampening spring and urethane impact pad, acting as a dead-blow weight
• Requires a compatible A5-length buffer tube and spring

Where a conventional heavy buffer simply adds mass to slow the bolt down, the RMB's sliding body and internal reciprocating weight are tuned to absorb and dissipate energy through the cycle, turning recoil impulse into more of a steady push than a sharp punch. Independent blind testing has reported reduced felt recoil and virtually eliminated bolt bounce compared to a traditional heavy buffer, with results most pronounced using standard-pressure ammunition; final tuning may vary depending on the rest of the build. This 5-ounce weight is specific to the Mike-15 platform, distinct from Foxtrot Mike's heavier RMB buffers built for their PCC line.

Foxtrot Mike Products has built a reputation on genuinely different engineering solutions rather than incremental tweaks, and the RMB System reflects that same focus on solving a specific mechanical problem rather than just adding weight.
