Hey Gents, My not so bright half-brother decided to fire a 7.62x39 out of a nice S&W 1500 .243 . Rifle blew in half. Stock in 2 pieces, blew mag door off and broke it at pivot pin, also blew apart the one piece mag well/trigger guard. the ejector is missing, the extractor is ok but the pin and spring are missing. I have repaired all the damage, but I cannot locate any parts for the .243 bolt. There is a Howa (also made same model 1500) that is out of a .308 on GB. I asked him to test fit a .243, which he did and posted pictures of it on GB. It looks brand new but the guy wants $150 for the complete bolt assy. Do you fellers reckon the Howa bolt face is the same as the .243? Can someone make some measurements of rim diameters and average thickness of rims and provide that info? Any other suggestions as well?
