First off when you star shooting, you'll get everyone's attention such is the boom! out of the 7.62x 54r.
As for accuracy 51 or so inches should mean something. A long barrel and tight groups go together. Furthermore on a standing position at 50 yards good groups are possible, holding my elbows close to the body gives good control over target acquisition.
About the condition, never heard anyone complaint about a shot out barrel as of yet, the crown on those rifles have been reworked
A good addition for the rifle is a scope, I've see this one with s& H is about $150
which is cheap compared with the real item which is almost $500
A cool enhancement on the iron sights is this one, luminescent sights from glow-on.com really help at indoor ranges check this link
