Threading a 303 Brit barrel

[fightinghamster]

Starting at 18 1/2", there is no margin to cut it off and start over. Gotta get it right the first time.
Speaking of brakes on a .303 - I installed a brake and front sight unit from a SVT 40 muzzle unit on a No. 4. The concussion is impressive.

I’d love to see that thing I bet it’s sick

Why not buy a clamp on brake? It would save you a lot of hassle.

I’ve tried looking at all the sites I usually look on and couldn’t find one, got any you recommend?

You're more than likely forced to remove the front sight base, in order to find a clamp on brake that will work. Then you can just try and attach a front sight to the brake.

I've got a friend with a no1 mkIII I put together for him. It was a mix matched parts bin rifle so the barrel was not mated to the receiver yet.
Had dlask do the barrel work , shortened to 19" and threaded 5/8x 24 with a recess crown and a 3 port muzzle brake installed.
Test firing that rifle was fun and I do think the brake improved the rifle handling during recoil but holy hell was it loud.
I hunt deer with a shortened down enfield and have built up quite a few of them now but I won't be wasting my money putting muzzle brakes on any of them. They are loud enough as it is LOL

Not a big deal I only just put it back on, I’ll be removing the rear sight and installing a rail/ red dot sight at some point anyway

Just not a good idea all around. Maybe you could take up fly fishing....

Nah that’s my wife’s hobby, I can’t stand fishing

6 port or the 2 port

I now want to make one

6 port. Numrich used to have the muzzle units cheap. Cut off the gas block, turned and threaded the Lee Enfield barrel to suit.

nice.

I built a muzzle device for an enfield that bubba put a 308 heavy barrel on. but that was before I got the milling machine, I may have to revisit that and make something better.

Bubba threaded the barrel 5/8' x 18 TPI, I guess that is the die they had ? I guess. It seems that it was at least done straight and fairly concentric, so I suspect it was started on a lathe and then cleaned up with the die.

Can I send it to you after I mess it up lol

No.

It actually is possible to run a die onto a barrel completely straight .... but it requires a lathe to hold everything aligned correctly.

The best way is to at least single point the threads to maybe 3/4 depth or so and then finish with the die. I do that with taps for internal threads sometimes to ensure the thread meets the correct spec.

yes that is the way I do most of my threading on the lathe, cut them close to finished profile then use a tap or die to cut the final profile.

Recently I saw annular cutters on the hooks at the local Princess Auto. The pilot would have to be precision turned to fit your bore. There was also another company selling annular cutters with various sized pilots available, advertised for use in barrel work.

A muzzle brake on it won´t be hilarious, honestly if I saw it at the range it´d just be another sporterised Enfield.

What would be far more interesting would be if you made a "Tanker" SMLE out of it and then maybe put a fake supressor on the end
