I have been looking around for an m1 carbine for sometime. On a trip to a local pawn shop, I came across a universal m1 carbine for a reasonable price. I like the rifle but there is a risk that if i buy this rife, that money might be wasted on a piece of metal that wont be worth anything. Is there any universal caribne owners that can give me some feedback in their rifel. Any advie? Should i go for it? How can I tell by looking at the carbine if its the old or newer Universal m1 carbine? How big of a risk would i be taking here?
