Default Midwest PX 16" 4140CM 1:8 Midlength Govt Profile Barrel!

Click the pic above to order

I'm happy to announce our first in a line of branded barrels has been made available for purchase! We have also decided to include it in our Black Friday deals!

Made from 4140 chrome-moly steel, our US-made, button-rifled barrels deliver excellent accuracy and performance at a modest price. 100% US-made barstock is delivered to our contractor in South Carolina where the steel is machined in-house. Our contractor does all operations but plating so they can better control the manufacturing process and ensure quality which in turn delivers a superior barrel.

We specified an eight twist in this barrel because it allows a shooter to use the widest range of bullets available to the platform, from thin-skinned, lightweight varmint grenades to longer, heavier 75 and 77gr OTM bullets and everything in between. The tuned gas port size means reliably shooting lightly loaded .223 as well as full power 5.56. Finally, the midlength gas port allows for more dwell time relative to a carbine length gas system which means less perceived recoil.

The muzzles are threaded in a standard 1/2x28 for all popular muzzle devices and thread-on suppressors meant for .223/5.56 use. The underside of the barrel is dimpled to assist in gas block placement. While we had the dimples measured for a Troy low profile gas block, any 0.750" gas block will work as the first dimple is universal in placement.

As with all Midwest PX branded products, this product carries a lifetime warranty against defects in materials and workmanship
