I agree, the LB's are nice. parts are readily available. But never regret having a few in the safe. thats the safest place for them.(yes pun intended).
be carefull of dirty bores, they could be hiding a condition typical of many LE's a worn out rifle bore from corrosion or poor cleaning practices.
around here they go for 275 to 350. but with a bad bore no more than 200. Criterion sells replacement barrels that are nice. reasonably priced.
with a new barrel it could become the beginning of a beautiful thing.
