Foxtrot Mike Products, a trusted name in firearm innovation for over nine years, proudly announces the launch of its latest advancement: the RMB (Recoil Mitigating Buffer) System. Designed specifically for pistol caliber carbines (PCCs), the RMB is a proprietary buffer system that dramatically improves performance, accuracy, and shooting comfort — while maintaining the affordability and reliability that Foxtrot Mike is known for.

This RMB Buffer is designed to be used with our VFM-9 Upper Receiver, as it is a "Short Stroke" style.  If you are building your own PCC upper that is not "Short Stroke" style. you would need an A5 BufFer Tube to ensure bolt lock back.  

• At the core of the RMB is a finely tuned reciprocating mass that eliminates bolt bounce — a long-standing issue in traditional blowback-operated PCCs. Combined with a sliding buffer body, a dampening spring, and a durable urethane impact modifier, the RMB system delivers a soft, controlled recoil impulse that users will feel immediately — and high-speed video testing the RMB with our VFM-9 5" confirms it: 100% elimination of bolt bounce.

  * no +P or +p+ used for testing 

  “Recoil Mitigation = Accuracy & Reliability.”  

  This is the guiding principle behind the RMB and the legacy Foxtrot Mike Products has built over nearly a decade of pushing the envelope. From proprietary in-house designs to widely respected white label OEM manufacturing, Foxtrot Mike Products has a rich history of developing reliable, economical, and feature-rich solutions for firearm enthusiasts and industry partners alike.

  In collaboration with industry experts and insights from Doug P. of Blowback9.com, a leading authority on blowback dynamics, the RMB was rigorously blind-tested — and the results speak volumes:

  • 100% of users reported noticeable recoil reduction compared to standard heavy buffers

  • Improved shot groupings during rapid fire

  • Complete bolt bounce elimination verified by high-speed video 

  FM performed extensive reliability and bolt bounce testing using a 5" VFM-9 Upper Receiver, longer barrels may perform differently.  The best recoil mitigation is achieved with a shorter barrel, no +P or +P+ ammo was used during testing.  There are many variables in a PCC build, individual results may vary depending on users set up.  

Whether you're assembling a new PCC or upgrading an existing platform, the RMB offers a superior solution for smoother shooting, better accuracy, and increased system reliability. 

PLEASE NOTE: The Recoil Mitigation Buffer must be used with an A5 buffer tube for proper function, unless using a short stroke bolt.
