So I SBR's my 10/22 on a Form 1. Put an engraved 4" Beyer aluminum barrel on it and so far I'm pleased. But the Butler Creek stock I got for it, I cut it down to fit which removes much of the forearm and the band. So the rear of the receiver moves up and down and any of you that have done this to a 10/22 knows what I'm talking about. I've read about other fixes but thought about this one and wanted to bounce it off a few other heads before I did it: My idea is to drill a (1/4, 5/16, 3/8 inch?) hole in the rear of the buttstock behind the folder portion, likely just above or just below the two screws that affix the folding assy. to the rest of the stock. Then I want to thread it to near the end to insert a heli-coil, with the last 1/4" or so drilled out a smaller diameter to allow a hex set screw to pass through, yet provide a good stop for the heli-coil (which I plan on epoxying in place). What I'd be left with is about a 1/4" thick set screw that places pressure on the tang of the trigger group in the 10/22 receiver assy. when installed in the stock. Sure, the folder would have to be removed to remove the receiver, but it would be clean. The other option is to drill the hole at about a 45deg. angle just above the folder assy. and install as above using a recessed hex head set screw that fits the heli-coil, and use a light thread locker. This would place a downward pressure on the tang which may perform the job better than placing it at no or a light angle underneath the stock, and perhaps a light divot could be drilled out on the tang and the bolt rounded off to provide a good contact. I wish I could draw a picture on here real fast, but if you have this stock and have SBR'd it, you know what I'm talking about. What have others done? I know for a fact this mod has been done up here. And do you think a heli-coil would work in the Butler Creek stock, epoxied and drilled to stop 1/4" before the end? Just want some ideas before I commit to drilling and I haven't gotten any answers over on a national site yet, but maybe this conversion is more common up here? Thanks in advance.
