Installed the barrel into my new under folding stock (PN:BLK-BLK-ST/PH1). Perfect fit, looks good, shoots great, packs nice.
Very happy, thank you.

Wore out my old barrel and bought this one dropped it in and it was already on zero great easy installation and loved the threaded barrel was a little disappointed that it didn't come with a flash hider already installed but still couldn't be happier

If it weren't for the barrel extention being to mount in a 10/22 receiver, you would believe this was an AR barrel. Fit was nice and tight in the stock receiver as well. This is in a Nordic Component chassis so it is free floated so fit was extremely important to me. Finish is what was expected. The only problem is now I need a new handguard so I can show the m4 style barrel off. Highly recommend.
