Foxtrot Mike ULTRALIGHT Premium 5" 1:16 Nitride .45 Cal Barrel - FM-BRL-455

So much of the weight of any carbine is often found in the barrel, and this fact led to many consumers clamoring for an ultralight barrel for their 9mm carbines and AR pistols. Foxtrot Mike Products stepped up with its FM-45 .45 Ultralight Barrels.

Each of Foxtrot Mike Products’ FM-45 .45 Ultralight 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.

• All-black finish
• Features 5/-24 TPI threaded muzzle
• Salt bath nitrided QPQ/Melonite finish

Each barrel is machined with 5/-24 TPI muzzle threads, designed for compatibility with most of today’s muzzle devices and suppressors. Foxtrot Mike Products FM-45 .45 Ultralight Barrels are built to work with all Colt- and Glock-style 9mm upper receivers and are machined with integrated feed ramps.
