I just bought this one! She's a 1981, all metal parts and has the A-Team style Butler Creek wire side folder woop! Bought it from a nice guy named Howard on the ODT. Told him to come check out this site...where's my handjob @dougiemac ?
I'd be building a frankin gun then. Buy one with a threaded barrel already (something like this, can probably find them even cheaper on gunbroker or similar http://jjgunsupply.com/p-1712-ruger-1022-synthetic-w-flash-suppressor-22lr.aspx). then take and swap the barrel and then sell the new one with the older barrel
