Frequently Asked Questions

What makes Criterion barrels stand out in the AR-15 market?

Criterion barrels are distinguished by their refined manufacturing processes, including advanced chrome lining that aims to preserve accuracy while enhancing durability. They also feature hand-lapped rifling for uniformity and polished chambers for smooth extraction, contributing to their reputation for quality and performance.

What are the key specifications of the Criterion Core 11.5-inch barrel discussed?

The Criterion Core 11.5-inch barrel is constructed from 4150 steel with a phosphate exterior and a chrome-lined bore. It features a balanced profile, tapering to a 0.625-inch gas block journal, and includes a 1:8 twist rate, making it suitable for a wide range of 5.56 NATO ammunition.

How does the 223 Wylde chambering benefit an AR-15 build?

The 223 Wylde chamber is designed to optimize performance with both 5.56 NATO and .223 Remington ammunition. It can safely handle the higher pressures of 5.56 NATO while maintaining the accuracy characteristics associated with .223, offering a versatile chambering option for AR-15 builds.

What is the typical accuracy expected from a Criterion barrel?

With match-grade ammunition, such as 77-grain Federal Premium or Hornady 73-grain ELDM, a Criterion barrel can achieve accuracy close to 1 MOA. Even with less expensive remanufactured ball ammunition, accuracy is generally around 2 to 2.5 MOA, which is considered adequate for training purposes.
