I traded for a near mint .303 british sporter, thing is pure shooter had it too under an inch in twelve shots with a bushnell banner scope! my question is the barrell and but plate have churchhill arms stamped on them. The barrell is 22" and is also glass bedded. the 5 round magsits flush on the bottom. It is a no 4 mk 1 rifle! I was wondering if the barrell was swapped out when it was sporterized! i traded 2 old simmons aetec scopes for it and I think I did all right! any help would be appreciated!
