The FM Products AR-15 9mm Build Kits give you a jump start on joining the trend of fun to build, fun to shoot PCCs.
FM Products has built up a solid reputation as a quality supplier of pistol caliber AR-15 components and these Build Kits take many of those key components and bundle them together to save you time and money.
Included in the 9mm Build kit is a stripped, Glock magazine compatible lower receiver, a complete 9mm bolt, a heavy buffer, a .308 buffer spring, a thread protector, and your choice of 5”, 7”, or 9.75" 9mm barrel.
The FM-9 9mm Stripped Lower Receiver is compatible with all 9mm Glock-style magazines and featuring last-round bolt hold-open, machined from 7075-T6 billet aluminum, and feature an all-black finish.
Each of FM-9 9mm Barrels are machined from 41V50 chrome-moly vanadium steel and are finished to provide match-grade accuracy and precision, thanks to a button-rifling process that cuts a 1:10-inch twist rate designed to stabilize all 9mm projectiles. Each barrel is machined with 1/2-36 TPI muzzle threads, designed for compatibility with most of today's muzzle devices and suppressors.
Machined from a single piece of premium 8620H steel alloy, the FM-9 Bolt is finished with a deep-penetration salt bath nitride that gives both lubricity and wear-resistance. As an added benefit, the FM-9 Bolt is “ramped” to accommodate both standard GI and dedicated 9mm hammers.
The FM-9 Heavy Pistol Buffer is the correct weight (6.4oz) to ensure reliable cycling of any blow-back operated AR-15 pistol action. With its extended length, the FM-9 Heavy Pistol Buffer requires no spacer and helps prevent bolt catch breakage. By installing this buffer, you’ll enjoy smoother function, less felt recoil, and reduced rate of fire from your AR pistol.
