M305 Barrel onto M-1 Receiver

Working on a hybrid project - M-1 backend, M305 front.
Beretta receiver, take-off M305 barrel. Barrel screwed in with an excellent fit, stopping just slightly short of indexing. Took .004" off the shoulder, and the barrel pulled up just right.
With one of the Springfield M-1 bolts from TradeEx, headspace is perfect, without adjustment. Closes completely without effort on the GO, partially on the NO GO, and not at all on the Field.
Turned a bushing from a piece of scrap rifle barrel for the M305 op. rod guide, to reduce the internal diameter to suit a M-1 operating rod.

So, to ask a kind of off topic question master frankengun builder;
Could an M305 receiver and stock, also accept an M1 barrel & gas system/upper hand guard/op-rod?

curious.....
 
The stock wouldn't work very well. Think about how the forend engages the barrelled action. I do not know if a M-1 operating rod would work on a M305 receiver. Have to try and see. You are thinking in terms of a .308 M-1 barrel?

No, just a curious question tiriaq.

Much like yourself, I also have a 308 M1 so I have no real need for another.

thought of trying this one too just have not gotten around to it, have built a number or m1 tankers in 06 and 7.62 in the 18.5-19 " range they are a bit of work but are very fun and nicely balanced. have also toyed around using BM59/62 parts for these.

Going from memory as I don't have an m14 in front of me, countersink and press in or tack a section of tube on the rear or the guide to carry the op to the full rear cycle, other option machine a new guide with a step in it so the lower lobe is farther rearward.

also keep in mind you may have to open up the gas port or use a adjustable gas plug to play with the gas pressure vs op spring to get a smooth full rear cycle. to me a bit to get that worked out for the 19" 30.06 garand

Hit a roadblock. I made a bushing for the op. rod guide to match the diameter of the M-1 op. rod. Seemed OK. So I whittled a new one out of a block of steel on the lathe and mill. Here's the problem. The op. rod hole in the guide must be relieved to clear the transition zone on the front of the M-1 op. rod. But if the transition zone of the rod clears the guide, the front end of a modified rod would come back further than the guide with the bolt open all the way. It would be hanging free, unsupported, when the bolt is fully open. The problem is that the operating stroke for a M-1 is longer than for a M-14. Trying to figure out a way around this impasse.

If the op. rod guide is extended to the rear to keep the op rod supported when the action is open, the extension will interfere with the op. rod when the bolt is closed.
