Barrel Shank Shimming ?



Log in to see fewer ads
Anyone one ever try shimming the barrel shank on a 10/22. I have one that is a loose fit even with a Green Mountain barrel, I am thinking I can get a .001" or .0015" shim to fit in there. Any improvement in accuracy for those of you that have tried this ? Thanks in Advance

Never going to get a shim in there, I always use "press fit" loctite.

Your going to have a hard time convincing me tight barrel fit improves accuracy. I just don't think there is enough violence created by sending a 22LR down range to move anything if the V-block is tightened properly. Eliminating droop.. I'll buy that but practical accuracy?? Not IMO. Having expressed my almost worthless opinion.. I use gunsmither V-blocks for peace of mind.

is that the old 640 bearing and sleeve retainer? It will do .007 gaps.

Well I managed to get a .001" shim installed, tightened the barrel up nicely, may have moved POI up a couple inches best I could tell and a slight improvement in accuracy which could have been luck that day.
