Ratings & Reviews
FMP 10.5" review - innovative, outstanding firearm
by Michael from Ohio -
Mated FMP 10.5” upper with a FMP premium lower. I found the side charging very efficient and effective while running drills at the range. Side charger and LRBHO offer excellent shooting experience with these features thoughtfully designed and executed in this firearm.
<br>I do have one criticism, the charging handle is not the folding shown is many product photo examples, but rather a shorter static handle the can lead to raking your finger against the side of pic rail if not cautious. I did deduct a star this reason. I will also note, FMP recommends avoiding Korean mags, and I did experience frequent FTF while using SGM mags, but absolutely no failures using Glock or Magpul mags.
<br>Of my AR-9mm PCC firearms, I most enjoy this pistol as it shoots extremely accurately and softly. I only shoot brass case 115 and 124 grain ammo, and experienced no failure nor issues when I adhere to FMP guidelines. Easily ring 6” steel at 75 yards using 2 MoA red dot while shouldered.
FMP Premium lower & 10.5" upper 350 round review
by Michael H -
Mated FMP Premium lower & FMP 10.5" upper and love the results with LRBHO. Ringing 6" steel at 75 yards easily with Mid-Ten 2 MoA red dot as a novice shooter. My home range will not allow longer shots shooting both 115 and 124 grn FMJ. I only shoot brass case FMJ, so I cannot speak for any other ammo flavor.
<br>One forewarning, using the included charging handle (not the folding handle that is shown in many example photos) may lead to skin loss while rubbing against the side of the Pic rail if not careful.
<br>Love the side charing and LRBHO, just wish the folding charging handle was included with upper. Cost this review one star.
<br>Now considering a 16" FMP upper, even with 9mm and marginal/minimal ballistic gain. Love this gun for plinking and home defense!!

Great lower, really high quality. Combined it with the 7in FM upper and an SBA3 brace. It’s a ton of fun to shoot, only had 1 malfunction after 500+ rounds. All the FM9 parts are really high quality, I love it.
<br>My only complaint is the trigger has a bit of creep and is a bit heavy. Will likely replace the trigger at some point.
<br>Other than that highly recommend it!
Great AR9 Lower
by Eric -
Picked this up as a black friday deal. Great lower, they have made some great improvements over a traditional AR9. The mag release button is perfectly positioned, large, and very easy to push without disturbing your grip. LRBHO works perfectly. <br><br>My only ding is on the trigger. It was full of creep and not consistent. Dropped in a Rise Armament Super Sport ($85) and have had no problems since.<br><br>I paired this with their 7 inch upper, magpul glock mags, and a sig romeo. Greased the bolt bearing surfaces and the gun has run flawlessly for nearly a thousand rounds. Eats every type of ammo I have (fiocchi, federal black packs, speer lawman, gold dot, winchester white box, HSTs, and hydrashoks). Is one of my favorite range toys. Everyone who shoots it has a huge grin on their face. Wouldn't be surprised if a few of my buddies pick one up - they had that much fun with it.
FOXTROT MIKE, Best 9mm AR in the market
by AL -
I received today my FOXTROT MIKE 5" upper and FM9 Premium 9mm Lower Receiver along with a few Magpul GL9 PMAG 15 Glock 19. After clear up the background check and completed the transfer, I when ahead and test the product. I shot out of the box (I just lubricate the 9mm bolt and trigger) 400 rounds without any malfunction. Very happy with my FM 9mm AR. Extraordinary quality and well machinery lower. The 9mm Ar Bolt Carrier Group is one of the best that I tested. Overall, I'm happy with FOXTROT MIKE performance. Shout out to the Primary Arms team to bringing these products to the market and for the alliance with FM.
