Hi guys, I recently got a few ex range rifles and sporters (all no1 mk111 and 111*). 2 have H barrels in excellent condition and two have their original barrels that are clapped out.
I want to make the 2 best H barrelled rifles I can out of the parts.

My questions are: is it indicative of some fundamental flaw in the bolt/receiver fittment if only the lug at the back of the reinforcing rail on the bolt body is polished(ie worn bright) and the other (the small one oposite) appears unworn?

if so is there any correcting this situation? ie. lapping etc


FYI the rifle in question is 1918 BSA mk111, the bolt is matching, and the original barrel is cactus. The rifle looks in reasonable condition, headspaces a little long, will close on a .067 but not a .074. I am suspicious it may have been reblued once upon a time.

Just wondering if this is one to built on. But I'm only interested in building excellent shooters.
