BLACKOUT DEFENSE AR-15 ELITE SERIES BARREL MID-LENGTH

Blackout Defense AR-15 Elite Series barres are top of the line button-rifled barrels that offer the highest degree of precision. It is not unusual for customers of Blackout Defense Elite Series barrels to shoot sub .75 MOA in optimal conditions using match-grade ammunition and other quality components.

The Elite Series barrels start with premium 416-R stainless steel bars that are gun-drilled and reamed in 5R rifling and 1:8 twist at the slowest production speeds for the most consistent bore and groove diameters. They are then slowly lead-lapped by hand and held to extreme tolerances, virtually eliminating tooling marks for an exceptional bore finish. The blanks are then fully stress relieved and precision air gauged before profiling, threading, and chambering begins.

Profiling and threading are completed on an ultra-precision 5-axis mill turn machine. The profile design includes three thermal expansion rings to prevent distortion of the barrel during heavy use, as well as an extended gas block journal to accommodate enhanced gas blocks. The muzzle thread is machined to ½ x 28 with an 11-degree crown. The barrels are chambered in .223 Wylde and individually inspected with a dummy round in addition to precision go and no-go gauges to ensure an accurate headspace. Finally, the barrels are hand deburred and polished to a consistent outer finish and salt bath nitrided for enhanced durability and corrosion resistance. The barrel extensions are Nickel Teflon coated for enhanced lubricity, and then installed to ensure a perfect torque.
