Hi there folks , I purchased a HS barrel for my most recent build . The wholesaler here in Canada tagged the barrel with a Brownells part number and a reference to it being a 1/7 twist . The problem is the Brownells part number refers to a stainless barrel ,FSB equiped,1/9 twist, .223 chamber. The only identifying marks on the barrel are the words "HI-STANDARD " on the top of the barrel under the hand guard, and a "G" on the top of the barrel just forward of the barrel nut . If anyone has information on my barrel it would be appreciated.

We only supply 20" barrels in a 1/7 twist with hard chrome lining. I think Brownell's might need to correct some typos somewhere in their system.
Best Regards,
High Standard Mfg.

Does this barrel have M4 feed ramps ? I'm looking for a A2 style 20" barrel without the M4 feed ramps.

oops.
