OpticsPlanet Exclusive FM Products Foxtrot Mike Premium Pistol Builders Kit, 8.5in, FM9 FM-8.5-PPBC
You can run a .223/5.56 AR lower but you have to get either a mag adapter for Glock that fits in your mag well or you can get some EndoMag conversion inserts to put in gen2/3 Pmags. The only way to get LRBHO is to get FM products dedicated Glock lower.
Product Info for OpticsPlanet Exclusive FM Products Foxtrot Mike Premium Pistol Builders Kit, 8.5in, FM9
Complete your dream weapon build by using the components of this FM Products Premium Pistol Builders Kit to turn your stripped small frame 9mm Glock-style lower receiver into an unstoppable force in the field, range or backcountry. Each of these AR15 Lower Parts crafted by FM Products is made from the highest quality materials and delivers amazing features that will improve your aim, handling and overall shooting capabilities. For example, the 9.75in ultra-light barrel is machined from 41V50 chrome-molyvanadium steel alloy with a salt bath Nitride QPQ/Melonite finish for maximum durability and premium resistance to corrosion and wear over time. This FM Products OP Exclusive Premium 8.5in Pistol Builders Kit includes a forward blast diffuser that mitigates muzzle rise and reduces recoil for pinpoint precision with every shot you take. You'll also create a more reliable weapon by installing this kit since the 6.4oz. heavy buffer ensures proper and smooth cycling with every round chambered, and it even further dampens recoil to help you land difficult shots and get back to target quicker than ever before. Check out the features below to explore all the ways this bundle will improve your firearm, and pick up your FM Products OpticsPlanet Exclusive Premium 8.5in Pistol Build Kit right here to see them all in action.
