I purchased it NEW from a Ruger dealer at a gunshow yesterday. It's a beautiful (lol) All Weather Camo stocked version. Now mind you, it was disassembled in the box and it went together fine on my first assembly. I followed the directions and removed the bolt again to add a little lube on the contact surfaces but when I went to re install it it goes up and hits against the rear of the channel on the lug. I didn't force it, but I just kept tapping back and forth to see where it was hitting and it was definitely at the very front part of the bolt. I could see a little mark where it was hitting. I was able to eventually get it to wiggle just enough to get it back in. Is this normal or just so tight tolerances that it is that close? I'm almost afraid to remove it in fear that I wont get it back in. I thought about the bolt shims maybe taking some of that slop out and allowing it to feed into that opening better too? Or perhaps polishing that edge a little?
