Was looking at a pict of a bolt release for a 10/22 in a popular web sight and took my bolt lock out and used a dremel tool, a file might work and it looks like a hart grind the center of the humps of hart out and give it a slight arch not much and now you have a automatic bolt release might take a couple of tries
Now for cleaning strip receaver, find dead center on the back of the receaver and come up .790 and drill a hole 1/4 or bigger not to much bigger and wala now you can clean your 10/22 like a bolt rifle.The way I came up with the .790 was look down the barrel and scribe the inside of the receiver or purches the jig for $35.00 I think. Do this at YOUR OWNE RISK and be careful
This is my present to all of you Have a Merry Christmas:usa: Make the first shot count because if you dont it wasnt a good shot
