Great replacement barrel - Revolution Stocks Replacement Threaded Fluted Barrel Ruger 10/22 16.5 Inch Blued .920 Diameter KSA10060

This barrel was easy to install. It shoots great. Now I will have to order a better scope to match the performance of this barrel. Only gave it 4 stars because I think the flutes are very shallow. I expected them to be more Significant which would have taken a little weight off of a quite heavy barrel.
