If you plan to build a 9mm pistol AR do yourself a favor! Buy this upper and the FM 9 lower! Save time and money.
Looks good works great

Love the side charge, very smooth. Used with FM lower which, as you'd expect, pairs nicely. All finishes and machining are better than I expect at the price point. The bolt is a beauty. Quality item. The company logo and all text is subdued and classy.
Awesome company to work with and great upper.
Thing runs great and shoots straight. Have mine sitting on a QC10 lower which required a slight modification to the ejector. Ran my first 350 rounds through her today mostly as a function check and not one single hiccup. Used factory Glock mags and Magul mags with no issues. 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).
Best 9mm AR upper

This upper has to be the best 9mm upper I own. It balances well, the forward charging handle is amazing. It's light weight love the slim handguard.
