RE: Sleeper
Yup, outstanding rifles. I have 3 of them, I paid $49 for the cheapest one and $100 for the most expensive one. Very accurate with surplus GP-11 ammo- the stuff is match grade ammo, and are easy to reload for- just use .308 winchester data.
I bought a clamp on scope mount for about $75 so that I could shoot it more accurately with a scope, for about $200 invested with a scope mount, it beats the heck out of most commercial rifles prices 2 or 3x as much.
If you haven't already, take the buttplate off and check for a tag. Half of the rifles or better have a tag under the buttplate that has the soldier's name and unit that once owned the rifle. The rifles usually only had one owner, a soldier was issued the rifle and kept it even after his service was over until he was around 50years old and then was given the option to buy the rifle for a small cost or turn it back in. There have been people who have successfully contacted the former owners, all with positive responses from the owners.
