No 4 Bolt and Bolt Head

[coltboy]

Finishing up a No 4 and all I have left is the bolt. The bolt it came with is mismatched S/N and is worn to point it is in the white. Also has a lightning hole drilled on it like a No 5 but this is possibly correct. Got a bolt body from Century with no S/N. When reassembling it the bolt head needs to rotate about 10 to 15 degrees to match up with the bolt body. I can unscrew it about 90 degrees and the bolt will slide into the receiver.

When in this position and when the trigger is pulled it moves in its space. I was reading that Enfield No bolt headscame in different lengths to facilitate proper headspace. Guess I am stuck with original bolt body. Any suggestions? Thanks. Jim

I would strongly suggest you read the threads on this site on the fitment of the bolt as it is not just a plug and play by swapping bolt heads to attain the correct head spacing it also has to bear evenly on the recoil lugs and surfaces on the bolt and in the receiver.
Bruce in Oz explains it is a helical lock up system.

These threads were supplied by those with years of experience with the Lee Enfield line, Peter Laidler, Brian Dick, Dr Roger Payne, Bruce in Oz to name just a couple of those that freely donate their knowledge & experience for the better good of the military surplus collectors around the world.

Failing that source a gunsmith who understands the rifles, allot of folk here ship their weapons to Brian Dick. BDL Limited ~ BDL LTD Weapons and Militaria
