Jungle carbine flash hider dimension quesiton
Hi everyone, quick question. I'm trying to buy a replacement flash hider (the one on a carbine I'm working on has had its bayonet lug removed...). Numrich has two types in stock; one with the interior diameter of 0.590 inch, the other 0.670. Which one will fit the original Jungle carbine barrel? Many thanks for any input... Hopefully I'll be able to finish this refurb, that's the only remaining glitch on this old carbine.

Been there, done that (on a P14)
Having put back the bayonet lug on a P14, may I recommend that you consider the use of a new-fangled device known as the milling machine? Only been around for a couple of hundred years, I know, but one doesn't have to do the total Khyber Pass thing. So you haven't got a milling machine? Neither have I. But I do have a milling slide for my lathe. It saves whole weekends of filing!
This is one of those situations where I (once again) recommend that anyone considering such activities should get in touch with (join?) a model engineering club. People who can build live steam engines from lumps of steel, copper and brass can handle just about anything that forum members are likely to need, and you will be amazed at the machinery that some MEs have acquired. One of the best examples of model engineering I can remember was at the Model Engineeering exhibition in Earls Court, about half a century ago - a 25-pounder field gun, scaled down to shoot 45 revolver ammo. Gun licensing was simpler in those days!
So mill the bayonet lug profile and get it MIGed/TIGed onto the flash hider body. You will need to make a simple jig to hold the two pieces in position for welding - even the best welder only has two hands. And you will probably still have some filing to do afterwards, to make the welding fillet as near to invisible as you can. Plus judicious wiping over with a bluing fluid to dull the shiny surfaces.
Of course, if you value your time, you will be better off buying a replacement. But that's no fun!
