"its a pretty good solution in my opinion. You really dont have to change much on the rifle , but allows you to have a scope. I was looking in to doing the same, but I had trouble finding a good scope with the right eye relief. where did you get yours?"

"Just off the top of my head, I know that some people use pistol scopes when the scope is mounted that far forward because they have a longer eye relief you need for this application.

Or, look up "scout" style or intermediate eye relief (IER) scopes. Leupold makes one."

"I shoot lacquered-cased ammo out of my Mosin-Nagant rifles all the time, and don't have sticky bolt issues on any of them, but at first I had similar problems too...

If I had to guess, there is probably still some old cosmoline or dried up gun oil in the chamber area of your old M91/30 rifle. What happens is that when you shoot, the receiver around the chamber area heats up and that old (and now warm) grease forms a rough glue on the fired cartridge cases. The effective is more appreciable on lacquer steel cased ammo than it is on brass ammo.

To fix this problem so that ANY ammo can be used without this problem, try using a 20 gauge bore mop (soaked in solvent) to clean the chamber out thoroughly. Make sure to thoroughly dry the chamber after cleaning too, and be careful not to over-lubricate your bolt. If you're still having a problem, inspect your brass - if there are any scratches or signs of over-pressure (OP mimics sticky bolt) on the cases you might need to make a trip to the gunsmith.

Speaking of Mosin-Nagant bolt lubrication, I use dry graphite lube (like that used on locks) to lubricate the inside of my rifle bolts rather than liquid lubricants. This prevents the lubricant from running out of the bolt, and is better for long-term storage than most gun oils. You can find it for a few bucks at any automotive store."

"The only safety I need is my index finger. "

"I bought a pre-war hex receiver Mosin on AIMsurplus.com for $80 and I can say I'm very happy with it. Before I put a scope on it, my old rifle with the bayonet on it was as accurate as can be expected with user error at 100 yards. The rounds are cheap as can be (440 rounds of Russian surplus for $80) and are powerful as hell. I solved my sticky bolt problem by rigorous cleaning and more particular ammunition selection. When it comes to surplus ammo for a bolt action never get the green lacquered steel cased ammo. I then mounted a scope on it, but that's a different animal. I like the longer Mosin because it becomes a heavy backed spear or a bludgeon. "
