Criterion Hybrid contour match grade .308 AR barrels offer an ideal configuration for those seeking extreme accuracy without the added weight of a heavy barrel contour. These .308 AR barrels feature a M118LR chamber. The longer throat of the M118LR enables Criterion .308 AR barrels to improve upon the performance of loads utilizing heavier bullets, serving to reduce wind drift when fired at longer ranges. This configuration is designed to accommodate either .308 Winchester or 7.62x51 ammunition, and comes complete with an installed barrel extension. CBI .308 AR barrels are compatible with DPMS, Remington, and Fulton pattern rifles, and accept muzzle devices with a 5/8x24 thread. An indent is provided opposite the gas port to enable easy installation. Chambers are finished, but headspace should be checked prior to installation. Chrome lined variants are available in 16, 18 and 20 inch lengths. These barrels are button rifled, and have been hand lapped to ensure consistent bore uniformity.

Accurate 15/03/2018

I bought one of these barrels before for a customer build, was surprised with the accuracy and bought one for myself. Iâve bought the 22â Criterion stainless target barrel and wasnât happy with the accuracy, actually enough that I sent it back to Criterion. This 20â chrome lined barrel is very well made, very accurate. 165 HPBT Sierra, 44.5 grains of Vit N-550, 1/2âfive shot groups at 200 yards.

Very accurate 22/10/2017

Installed it on a Aero upper receiver with JP lightened bolt and adjustable gas block, and the JP one piece buffer spring. Once sighted in with .308 Win 147 grain bullets ( various brands) at 100 yds using a Night Force scope. It was able to hit a 20 inch round plate at 600 yards. The group was a little less than 10 inches. Using Remington and Federal match grade ammo, the group tightened up to around 6 to 8 inches. Using IMI match brass, Vihtavouri powder, and the 165 grain Hornady match bullets (new custom loaded), the group tightened up to about 5 to 6 inches, and thats at 500 and 600 yards. Mostly in the 5 inch or less range. Range only go up to 600. No wind, temp was about 80 degrees.

Perfect 16" .308 Barrel 29/09/2015

Fit and finish on this barrel is amazing. The phosphate finish is so dark, you'd think it was nitride and the chrome plate just wraps up into the crown, forming a perfect concentric. Melonite is awesome, but the jury is still out on what that second dose of high heat does to the metal after it's already been treated. That's why I prefer old school phosphate and chrome lining and this one's treatment is top notch. When a company goes to the length to do such an awesome job with the chrome, you know they are pros. One of the reasons melonite is so popular is because it's easier to do than chrome lining, so is it better, time will tell. The ramps and lugs are sharp and smooth. The profile isn't heavy, but obviously not government either. It's between the two, but leaning towards heavy, which I prefer. The shoulder for the gas block is perfectly cut, and the dimple was just slightly more towards the shoulder than the gas block set screw hole and had a little depth to it. This is good because as you torque the screw down it pulls the block up close to the shoulder. Not sure if that is the case with all blocks, but that's how it worked with my Spike's lo pro block. It also fit my Aero Precision upper perfectly AND they are made in my home state! What's not to like!
