Is the Stock a real USGI Fiberglass stock, or the crappy plastic "synthetic" stock that Springfield has been using since actual USGI Fiberglass stocks ran out?
If so, keep it in the USGI Fiberglass stock as you will have better accuracy (wood swells & warps in wet & heat & dry & snow & ... ... ... )
Single lug or does the barrel have a second lug at the back of the receiver?
Is the action fiberglass bedded into the stock?
If the barrel HEAVY? (of large diameter without taper from chamber all the way to gas system?
Has the Gas System been "Unitized" (gas cylinder & front ferrule are normally separate pieces but match rifles drill & tap for screws & glues to hold them as a single unit for consistency & accuracy)
N.M. Operating Rod Guide? Is it flat or cruciform or round?
N.M. Hooded rear sight?
Does it have a NM Flash Hider (bored wider to prevent bullet contact)?
Does it have the bayonet lug on the Flash Hider? (in case you need to do a drive by bayonetting?
)
Some things you should know before you go...
Are you wanting a actual match shooting 7.62x51 rifle?
A Bang Around gun?
