Details

The Criterion AR-15 Hybrid barrel is designed for extreme accuracy without the added weight that a typical HBAR contour has. These barrels are chambered in .223 Wylde with a 1:8 button rifled twist rate to squeeze out every bit of accuracy possible. This barrel is machined from stainless steel and then finished inside and out with a Nitride QPQ process which results in a harder than chrome surface. This process creates an extremely wear resistant bore that is slick and easy to clean. This 18-inch barrel is built with a rifle length gas system and an optimized gas port size to ensure reliable function with both 5.56 and .223 ammunition. If you are building a new AR-15 and accuracy and reliability are at the top of your checklist, check out the Criterion Hybrid line of barrels.

Features:
  • 18” barrel with .223 Wylde chamber
  • Hybrid barrel contour
  • Nitride finished inside and out
  • 1:8 button rifled twist
  • Rifle length gas system with .750” diameter
  • Dimpled beneath the gas port
  • Weight: 2.20 lbs

This Criterion AR-15 barrel also features a dimple beneath the gas port for set screw style gas blocks. This makes sure that the gas block is securely mounted and won’t move around while firing. This Criterion Hybrid barrel is built to withstand years of heavy use while providing exceptional accuracy.

Criterion Barrels are known for building high quality, precision AR-15 and AR-10 barrels as well as barrels for older firearms like the M1 Garand, M14, and Lee Enfield. Their barrels are used by the US Army Marksmanship Unit Action Shooting Team and the US Marine Corps Combat Shooting Team and are proven to win matches time and time again.

I purchased this after shooting the 16" hybrid barrel. Quality manufacturing. Great fit and finish. Easy to clean, shoots straight.

Great value

I’m 100 rounds into a careful break-in on my 18” 1:8 Criterion barrel for a budget .223 Wylde DMR upper without breaking the bank. Good looking finish and bore. Everything went together smoothly with Aero parts and Rubber City BCG. Gas block dimple was properly located, and gas port is generous. Barrel-to-receiver fit, while not sloppy, was not super tight either, so I set it with Loctite 620.

Bore cleans up easily. Managed a couple of 0.8” 5-shot 100 yd. groups yesterday with IMI 77 gr. OTM Mod 1 (MK262 clone). Most other factory loads ranging from 55-77 grains were coming in at just over an inch but it got a little breezy. Barrel shows no particular preference between .55 vs .223.

Overall, I’m quite satisfied with results thus far. I think it will get even better with continued use. What more can you expect from a $200 barrel?! BTW, order was delivered in 23 hours!! Thanks PA for great selection, prices and service!!
