I do know that several of the OEM accounts do specify a lower quality barrel.
I can not speak for the OEM Grade Barrels that are manufactured at Criterion but the Stainless Match that I do order have been extremely high quality barrels. Having said that, anything that is manufactured can have an issue.
Yes Jim, a lot of people don't realize the above statement, and the same applies to several barrel makers!

The second statement, second sentence, also applies to all barrel manufactures!

Thanks for the statement, and I will look forward to doing business with you "again".
