The Criterion Barrels CORE .223 Wylde Carbine AR-15 Barrel is designed for tactical shooters, offering improved weight distribution and handling. The continuous taper profile redistributes weight around the chamber, improving heat dissipation and balance for better control and stability with modern accessories like optics and suppressors.

Features:

  • 11.5" barrel, continuous taper profile
  • .223 Wylde chamber (fires 5.56 NATO and .223 Rem)
  • Chrome-lined bore
  • Honed and hand-lapped rifling, polished chamber
  • Tuned gas port
  • Carbine-length gas system
  • Threaded 1/2x28
  • 1:8 twist
  • 1.35 lbs weight


The .223 Wylde chamber ensures reliable, accurate firing of both .223 Remington and 5.56 NATO ammunition, and the chrome-lined finish provides exceptional durability and corrosion resistance. Honed and hand-lapped rifling ensures consistent bore uniformity and superior accuracy, while the polished chamber and tuned gas port support smooth operation and reliable extraction.

Criterion Barrels builds high-quality, precision AR-15 and AR-10 barrels, as well as barrels for legacy platforms 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, proven to win matches time and time again.

Top Shelf Barrel

I mated this 11.5" chrome lined barrel with a BCM upper, BCM gas block, BCM BCMR-10 10.5" rail, BCM H2 buffer kit, AP lower, AP BCG, Geissele SSA-E and SBA3 brace. Criterion barrels are unobtainium. I waited over a year for my 308 barrel. Fortunately I got this before they were gone.

This is the best shooting firearm I've ever run! I'm 200+ rounds downrange now and I feel like a "real shooter". I'm not, of course, but it feels that way. Best explanation, it's 100% predictable. Running bill drills, failure to stop drills and target transition drills my confidence is elevated. I'm running a Holosun 510C-G (2 MOA) and at 50 yards I can group it under an inch without a proper rest or magnifier. Bill drills, 8 paces, 100+ rounds I'm getting 1.78 second times with 95% Alpha's. This is NOT the norm for me. Ejection is consistent at 3:00. Recoil is minimal. I'll have more data soon but for now.... wowza!

I love this setup and Criterion is at the heart of it.
What a joy to shoot.
