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 8 twist, gas port drilled at .125 and set up for pistol length gas system with a .750 gas block diameter
  • Barrel is chambered as .300 Blackout
  • They are Drilled, Reamed, Rifled, Turned, and if Applicable, fluted on CNC Machines. All our Finished Barrels go through a 100% Inspection Process.
  • Inspections Equipment includes CMMs and Air Gauges for the Bores.
  • Inspections Equipment includes CMMs and Air Gauges for the Bores.

These barrels are made from 4150 Chrome Moly Vanadium 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.
