has anyone ever modified a 10/22 ruger receiver to accept a takedown screw or bolt with a different thread pitch than the stock parts?
just looking at it, i am not sure whether it would be safe to re-tap that hole for a 1/4-20 bolt.
read on for the bigger picture.
i have a whole bunch of ideas on pillar bedding with department store parts for pennies on the dollar compared to most 10/22 bedding techniques i've seen. i like the how-to's on rimfirecentral, but they all do custom metal work to get a workable pillar, and i would like to find an off-the-shelf alternative that requires little or no grinding, welding, polishing, etc.
to that end, i have done some shopping and i picked up a set of four zinc-coated insert nuts at home depot similar to YM-606 in this photo. the catch is that you just don't find these anywhere in #12-24 coarse. non-threaded spacers in the plumbing and screw hardware sections of HD was not impressive at all.
option one is to keep looking for a better spacer with an acceptable flange.
option two is to drill out the threads entirely. i can do this, but your average 10/22 builder can not.
option three is to heli-coil from whichever TPI the part comes as down (or up?) to #12-24 coarse. this is relatively costly if you don't already have access to the kit.
option four is to pop out the brass nut in the 10/22 stock and have a gunsmith re-thread the receiver in 1/4-20. which is what i'm most curious about, since the others are trivial.
