If you are like me and cannot help assembling a 10/22 or 10 these are a great deal. I received one and have another on the way. The barrel I tried fits way tighter than in a Brownells receiver and has an extended rail on top. Just missing the cleaning hole in the back of the receiver. My buddies kid 3d printed a jig for that, so I will resolve that even though I have never used it on my others. $113 buck shipped is pretty good. Please buy them, so I do not buy anymore.

Just to add a note, I have one of their complete 22LR rifles, and it's surprisingly well made for the price.
If I was looking to get or build one more 10/22-style rifle, this would be it.
