This is the one you want!
This lower receiver worked flawless when paired with their upper and a 6.5oz heavy buffer. Fed a steady diet of steel and aluminum cased ammo without a hiccup! You don’t want any problems with your AR9 build or hours trying to tune it up? This is the path to go!
Great Glock mag lower

Great quality billet lower. Paired with a 10.5" FM Products upper, and an ALG ACT trigger, and it functions flawlessly! Last round bolt hold open works great with numerous Glock, Magpul and ETS brand magazines that I have tried. This was the first 9mm Glock mag lower that I built and it was super easy with the FM Products lower.
Best 9mm billet lower on the market!!

Billet lower was perfectly machined and anodizing was flawless.The last round bolt hold open worked great, no issues at all.Paired with an fm upper and matched trigger it is one of my favorite rifles.Great product and a great value.

Very happy with my FM-9 billet lower. The build quality is extremely nice with a dark , slick , anodizing , and not dull grey , or rough as you might find on cheaper forged lowers. There are also no visible machining marks either.
<br>I built this with a Spikes LPK and a Larue MBT , and paired it to the Foxtrot Mike 10.5" upper and it has been 100% reliable so far. The last round hold open works with all my glock and magpul mags.
