[QUOTE="Pdvdh, post: 427199, member: 4191"] Interesting. All the threads do is keep the barrel shoulder tight to the receiver face. If that 'machined... tight slip fit' of the mating surfaces of the barrel tenon into the receiver is snug enough, long enough, and strong enough (supported with enough steel in the thickness of the surrounding receiver), I suspect it will be a shooter. Having the bolt lugs lock into the barrel rather than the receiver could be beneficial to accuracy. Again provided there's enough mass of steel where the bolt lugs engage the barrel to endure the stress of repeated fire and use. One question. Is the hardness of the steel used in barrels equal to the hardness of the steel used in the manufacture of bolts and receivers? I don't know the answer to that, but one of you gunsmiths will. If barrel steel is softer than receiver steel, then the bolt lugs might set back the barrel steel under recoil - where the bolt lugs make contact with the barrel. You ought to post some pics!
