I recently picked up a CMP Garand at the north store and am quite pleased with it. While at a gun show I found a walnut stock, just the stock w/out hand guards, that was in great shape for $35 so I picked it up. I am having trouble fitting it to my Garand. It fits fairly well, but when I try to lock in the trigger group, I can't pivot the trigger guard all the way into the locked position. Aside from having a slight gap between the bottom of the receiver that is exposed above the stock and the top of the stock, which should be eliminated if the trigger guard locks down, it fits great. Has anyone had a similar problem? Are there certain measurements that the stock should be? I just want be cautious before I start sanding away.
