The Foxtrot Mike Products AR-15 .45 ACP Build Kits give you a jump start on joining the trend of fun to build, fun to shoot PCCs.

Foxtrot Mike 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 .45 ACP Build kit is a stripped, Glock®magazine compatible lower receiver, a complete .45 ACP bolt, a heavy buffer, a .308 buffer spring, a thread protector, and your choice of 5”, 7”, or 16” .45 ACP barrel.

The billet MIKE-45 lower receivers are stripped down for your Mil-Spec triggers and lower parts, but also includes a pre-installed proprietary bolt release and magazine release. These are designed to feed from Glock® .45 Auto magazines and features a last round bolt hold open. The MIKE-45 stripped lowers are machined from 7075-T6 billet aluminum and feature an all-black finish. The receivers are completely made in the USA and are covered under a lifetime warranty.

The Foxtrot Mike Products .45 ACP Barrels come in either 5”, 7” or 16” lengths with a 1:16” twist rate and are machined from 41V50 chrome-moly vanadium steel and are finished to provide match-grade accuracy and precision thanks to a button-rifling process. The muzzle is threaded 5/8-24 and includes a thread protector.

ThE Premium .45 ACP Bolt Assembly is compatible with all 45 caliber Glock®style Pistol Caliber AR builds. Maintaining a harder core than standard 8620 steel, this carrier is machined from Premium 4340 Steel. The outside diameter is precision ground prior to machining in a pre-hardened state for improved tolerances post machining and coating. A long duration salt bath nitride finish is applied for a long service life and superior corrosion resistance.

The Foxtrot Mike Products Extra Heavy Pistol Buffer (7.8oz) has internal Tungsten weights, to improve cycling of any blow-back operated AR-15 pistol action. With its extended length, the Foxtrot Mike Extra Heavy Pistol Buffer requires no spacer and helps prevent bolt catch breakage.
