BLACKOUT DEFENSE BARREL AR-15 223 WYLDE COMPETITION SERIES 16" LAPPED MID SUB MOA 92234

Blackout Defense AR-15 Competition Series barrels are exceptional button-rifled barrels that are designed for precision.  It is not unusual for customers of Blackout Defense Competition Series barrels to shoot sub MOA in optimal conditions using match-grade ammunition and other quality components.

The Competition Series barrels start with premium 416-R stainless steel bars that are gun-drilled and reamed in 5R rifling and 1:8 twist at slower production speeds for more consistent bore and groove diameters.  They are then slowly lapped to reduce tooling marks and achieve a superior bore finish for increased accuracy.  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 then 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 finish and salt bath nitrided for enhanced durability and corrosion resistance.  The barrel extensions are Nickel Teflon coated or enhanced lubricity, and then installed to ensure a perfect torque.
