Brutus' Description

This is a premium grade 7.5" Parkerized AR-15 pistol barrel from a highly respected U.S. contractor / barrel manufacturer.
These premium barrels are renowned for their deep, crisp, and consistent rifling and extreme accuracy.
When it comes to AR-15 barrels these Beautiful M4 Contour beauties are the granddaddy of them all.

1 in 7 twist, gas port drilled at .076 and set up for pistol length gas system with a .750 gas block diameter
Threaded for any standard AR-15 compensator. 

Barrel Extension in rear with M4 feed ramps ready to install into any standard AR receiver.

Barrel is chambered as ..300 Blackout

1 in 7 twist tends to stabilize the heavier grain weight bullets better.  

These barrels are made from 4140 cold rolled steel and are rated at a barrel life of approximately 150,000 rounds. They are very top end. 

They are not chrome lined as most AR15 barrels are not. Chrome lining on modern rifles is typically used where there is a high probability of corrosive ammo being used such as AK type rifles chambered for foreign calibers... 

Since chrome lining may slightly affect accuracy, and since most AR-15 rifles are designed with accuracy as a benchmark, 
and since virtually all .223 / 5.56 NATO is non corrosive...most AR manufacturers do not chrome line barrels. 

 

What a deal.......

Each parkerized barrel starts with 4140 Gun Barrel quality steel. Heat Treated and Stress Relieved to a hardness of Rockwell C 28-32.
Or we use the 416 Gun Quality Stainless Steel for our Stainless Steel Barrels.

These high quality barrels are manufactured on modern CNC equipment to completely machine the barrel. We drill, ream, rifle, turn, chamber ream, pin the Barrel Extension, drill the gas hole, and mill the flutes, all on late model CNC Equipment.  The Barrels are manufactured under the ISO 9002 Quality System, and each barrel goes through a Final Inspection before shipping.
