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).
