Reviews & Ratings for FM Products Foxtrot Mike FM-9 Monolithic 9mm Upper Receiver — 8 reviews — Page 1

I absolutely love this gun. Super fun to shootver accurate and reliable. To me its comparable to my sig mpx. If you in to pcc i would recommend you getting one of these. Ships right to you, primary arm was a pleasure to deal with. Great customer service.

I use my side charging 16 inch carbine for pcc competitions and have never had a failure to feed that wasn't a problem with a reload I made. I use primarily ETS clear magazines all work well and i love the 40 rounders. I did have some magazine problems with the stock springs but wolf springs cured that problem.

The side charge is cool and ambidextrous for you lefties, but I wish for an ambi bolt release, guess you cant have it all. Last week I had a roll pin bust in the bolt weight but was very easy to replace. I also added a taccom buffer and its a very smooth shooting carbine. Customer service is great and Paul Noonan is super helpful. Its easy to clean and runs excellent. I learned that the difference in the fm-9 and other carbines is the magazine angle, its designed to use glock mags but what most people fail to recognize is that the glock pistols rock the barrel for feeding and not so in a carbine which led to many feed problems with pcc's using glock mags.

FYI like many I started with the ruger pcc and i liked it but it was very heavy and not suitable for USPSA run and gun. The fm9 is the perfect match of weight speed and accuracy. All for half the price of a JP carbine

Unit is built very nice, shot very accurately with Syntech 130 ammo, so far no malfunctions using MEAN mags. My side charging handle is not folding, but I do not mind it. The side charging is a great feature to have!

The charging handle Tou get is not the one advertised...it's tiny and doesn't not fold at all...slightly annoying. Also had my firing pin get slightly deformed after 30 or so rounds and I had to dissemble and actually pull the firing pin out with a pair of needle nose pliers....polished the deformity on the pin for a bit and it's been running smoothly since. Still giving it 4stars, excellent product other than those two complaints

Awesome upper receiver, great quality well made and just reliable . A must for anyone building their own AR 9mm.. I'm definitely buying the 45 acp next!the price is very good and maybe get it even cheaper if you shop around ..

I like the fold down charging handle.... I wonder why more companies don't offer this feature... and the gas deflector that appears to be removable or replaced by a larger version. Other then its impressively good look it functions as good at it looks.So far it ran great on glock lower as it should.
