Great company with great customer service.


Thing runs great and shoots straight. Have mine sitting on a QC10 lower which required a slight modification to the ejector. I'm up to a case of ammo through my creation using factory Glock mags of various capacity and Magpul Glock mags without a single hiccup. Love the blowback gas system, and side charging handle. Was going to go the Scorpion route but figured this was the best of both worlds considering I carry a Glock 17 and had quite a few AR spare parts I could use. Great customer service as well, FM Products stands behind their work and will definitely help you get your build squared away should you have any issues. Tell them Ed sent you (thumbs up).

Great Hardware and Great Customer Service


I purchased mine earlier this year, combining the FMP Upper with a Matrix lower. I had some issues getting reliable extraction and FMP immediately provided help and suggestions that got the issue resolved. Can't recommend them highly enough.

Completely different level


FM-Products (Foxtrot Mike Products) takes their customers seriously. The attention to their customers is in a league of its own. The company responds to inquiries in light speed, just amazing. Such a great commitment to customer service deserves to be commended publicly. FM Products (Foxtrot Mike Products) is on a completely different level than most of the gun industry because of the focus on the quality of its products (I own two), and the personal energy and commitment of their corporate leadership. Well done Paul!



The Glockstore offered a 12% discount on the FM-9 PCC. I bought the 16"upper and built it with the video as a guide (I'm no gunsmith). I shot it at a steel match and it performed as advertise. I'll replace the Trinity Force buttstock (made in china) because it wobbles. This AR-15 PCC is attracting attention from my fellow shooters. Some fellow shooters have queried me about its manufacturer. Great job Foxtrot Mike. P.S. make sure to Loctite the screw on the ambidextrous selector or safety.

Foxtrot Mike has the best customer service in ANY industry.


I have never encountered a company, in any industry, that stands behind their products as much as Foxtrot Mike. They look out for their customers like they’re family. I shot better with my FM-9 out of the box than a CZ Scorpion EVO I’ve been shooting for years. If you’re on the fence about which pistol caliber carbine to get, look no further. You won’t regret it.

Incredible Customer Service!


Ordered a Foxtrot Mike upper and when it came in, it was missing a screw in the handguard. I called Foxtrot Mike and they said that never should've happened and seemed quite embarrassed. Five days later I received an entire bag of screws and an extra handguard barrel nut.

All I requested was one screw but Foxtrot Mike went the extra mile and provided me with a lifetime of screws and an extra barrel not in case I ever had a problem.

Way to go Foxtrot Mike, not only do you make an excellent product, your customer service is even better.

FM-9 for IDPA PCC competition


Bought this for IDPA, pcc competition. First time doing pcc division did not want to spend $$$ on some products like the JP rifles. Rifle shoots far better than I can. Single hole groups at 25 meters. Only complaint is the charging handle size and shape. IMIO it would be nice to be able to get two fingers around the forward charging handle and go with a round handle rather than the flat plastic handle as issued. That is the reason for four stars rather than five.

Other than that, rifle (FM-9 lower and upper) is solid and functions well.
