Solid durable quality part - Tactical Solutions X-Ring V-Block Upgrade for Ruger 10/22

I received the part and installed on my custom ruger 10/22 rifle, you don't have to worry about deforming or gouging out unlike aluminum blocks if you overtorque the screws by accident. It's always good to dab a drop of loctite 242 to make sure your screws don't come loose and the barrel coming off. Overall it's a solid quality part.
