I considered barrels from Douglas and White Oak Armament, but the Criterion barrel’s reputation for consistency and its optimized twist rate for heavier bullets swayed my decision. The price, at $332.49, felt like a worthwhile investment for the potential performance gains.
My first impression was one of excitement tempered with anticipation. This barrel looked the part, but the real test would be how it performed on the range. I was eager to see if the Criterion Barrels AR-15 Service Rifle DCM TARget Crown Barrel could finally deliver the precision I craved.
Real-World Testing: Putting Criterion Barrels AR-15 Service Rifle DCM TARget Crown Barrel to the Test
First Use Experience
I tested the Criterion Barrels AR-15 Service Rifle DCM TARget Crown Barrel at my local outdoor shooting range, known for its challenging wind conditions. I mounted the barrel on a meticulously assembled AR-15 lower receiver with a Geissele SSA-E trigger and paired it with a quality upper receiver and optic. Conditions were partly cloudy with a slight crosswind, making for a realistic test environment.
The barrel immediately impressed me with its consistency, even in the gusty wind. My first five-shot group at 100 yards, using 77-grain Sierra MatchKings, measured just under 0.75 MOA. The action felt smooth, and the rifle cycled reliably without any hiccups.
I did notice a slight increase in felt recoil compared to my previous, lighter barrel, but this was expected given the heavier contour. After about 50 rounds, the accuracy remained consistent, with no signs of heat-related shift.
Extended Use & Reliability
After several months of regular use, the Criterion Barrels AR-15 Service Rifle DCM TARget Crown Barrel has proven to be exceptionally reliable. It consistently delivers sub-MOA accuracy with match-grade ammunition, making it a joy to shoot at both short and long ranges. I’ve put over 500 rounds through it without a single malfunction.
The stainless steel finish has held up well, showing only minor signs of wear around the gas block journal. Cleaning the barrel is a breeze, thanks to the hand-lapped bore. Carbon fouling wipes away easily, and there’s no evidence of pitting or corrosion.
This barrel has significantly outperformed my previous experiences with standard AR-15 barrels. The Criterion delivers consistent accuracy, even after extended shooting sessions. It has exceeded my expectations for a service rifle-style barrel.
