FM PRODUCTS

This VFM-9 5" upper combo comes with a RMB (Recoil Mitigation Buffer).  A great option for a builder who already

has a PCC Lower they want to use.  The RMB is designed to work with a standard Carbin Buffer Tube,

because the VFM-9 Upper is a "Short Stroke" style, offering consumers the best results for recoil mitigation and reliability.

• 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.  

Foxtrot Mike Products  has built a reputation
for delivering high-quality, reliable, and feature-rich products, supported by outstanding customer
service. Recognizing the challenges faced by hardworking blue-collar consumers with reduced
discretionary income, Foxtrot Mike has introduced the VFM-9, a new line of 9mm Upper Receivers
that combines the same superior quality, durability, and innovation customers expect, at a more
accessible price point.

The VFM-9 is the clear choice for consumers seeking exceptional value without compromising
performance. By eliminating the complex barrel nut and implementing a thermal fit between the
barrel and the upper, Foxtrot Mike has reduced manufacturing costs while maintaining their
commitment to excellence. The VFM-9 features a robust 4140 steel barrel, offering impressive
accuracy and a service life exceeding 10,000 rounds. While slightly different from the premium 41V50
steel used in the flagship Mike-9, the 4140 steel still delivers outstanding performance for a PCC build.
Additionally, if a consumer ever shoots out their barrel, Foxtrot Mike offers a replacement for just
$99, further reinforcing their dedication to customer satisfaction.
The VFM-9 comes with a 5.2" barrel with a 1/2-28 thread and benefits from streamlined assembly
processes, including a reduction in handguard screws from eight to two, resulting in greater
production efficiency and cost savings—savings that are passed directly to the consumer. While some
parts of the VFM-9 are proprietary (with the bolt and muzzle device being interchangeable), this
upper is backed by Foxtrot Mike’s renowned lifetime warranty, ensuring peace of mind for every
purchase.
For those who still desire the premium materials and modular design of the flagship Mike-9, Foxtrot
Mike continues to offer this product line alongside the new VFM-9. However, for value-conscious
buyers, the VFM-9 stands out as an unbeatable option, delivering top-tier performance, precision, and
reliability at a fraction of the cost of competing products.
The VFM-9 is offered in two versions, one with a Forward Charging Handle (all metal charging
handle and trolley) as well as a Front and Rear Charging version, a great option for people with training on
an AR-style manual of arms.
Available through Primary Arms and the Foxtrot Mike web store, the VFM-9 represents a smart
investment for anyone looking to build or enhance their PCC without breaking the bank. Foxtrot
Mike’s proven reputation for quality and customer service makes the VFM-9 the obvious choice in
today’s market.

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.

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 confirms it: 100% elimination of bolt bounce.

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 VFM-9 series uses a short stroke compatible bolt, allowing this combo to function properly with a carbine buffer tube. However, when used with uppers other than the VFM-9 (such as our MIKE9 uppers), the recoil mitigation buffer will require an A5 buffer tube for proper function.
