Frequently Asked Questions

What makes the Foxtrot Mike Bolt Carrier Group (BCG) different from standard AR-15 BCGs?

The FM BCG features a recoil lug on the gas key that interfaces with a machined pocket in the carrier. This design distributes recoil load, preventing the common failure point of broken gas key screws seen in standard AR-15s.

How does Foxtrot Mike achieve 1 MOA accuracy with their 9mm barrels?

Foxtrot Mike implements rigorous quality control, including 100% inspection of every barrel using air gauges to check bore and rifling at every inch. They also utilize precision machining and high-quality materials like 41V50 steel with vacuum stress relieving.

What is the advantage of Foxtrot Mike's bufferless recoil system?

The patented dual nested recoil spring system eliminates the need for a traditional buffer tube. This allows the entire operating system to be contained within the upper receiver, simplifying the design and potentially reducing overall length.

How does Foxtrot Mike ensure barrel longevity and accuracy during assembly?

Barrels are made from 41V50 steel and vacuum stress-relieved. The barrel extension features machined flats allowing for precise 150 lbs torque application during assembly, ensuring a secure fit and preventing loosening.
