With my second M14 build, I'm replacing the front gas lock with a front gas lock sight. Which brings me to - what do I do for a brake/flash hider, since I no longer need the old front sight?

Will any old 7.62 brake/FH with 5/8x24 threads fit? Or is there some sort of special metric thread that I need to find or modify?

Its a 2011 imported norinco shorty if that makes a difference.

No. Only M14 muzzle devieces will contect to the end of said barrel.

So something like this M14 Direct Connect Compensator will fit? Doesn't matter if its a chinese or USGI barrel?

The threads on the Norcs is close enough to allow the SEI DC Vortex to thread on..............I ran the DC Vortex on a couple of Norcs I owned with the factory barrel.......

Well, that answers my question. I guess I will be in touch with Armtac towards the end of the month.

Just make sure to add atleast 2 passes of the yellow gas fitter's teflon tape around the treads and to ensure that the muzzle deviece is properly attached to said rifle. I have been hooing and haaing for Dlask to make a muzzle adaptor for the chinese m14 thread pitch to accept the 858 muzzle brakes for the longest time. But with the sudden increase in online sales he has been getting because of the situation in the states it has left him with very little time to manufacture this deviece.
Just wish that there was a machinist out there that could make this deviece as I don't even care for the money just to be able to purchase a deviece that no longer have to worry about getting certain muzzle devieces or that you can not use your iron sights cause they are as bent as the Chinese government really po's me.
If any one out there wants to make such a thing PM and I will fill ya in with the details but I do want to be the first one to buy such a deviece :p

Apparently the US made M14 has the following muzzle thread:

Per USGI drawing F7790190, the M14 barrel muzzle thread dimensions are

0.595 - 32 NS - 3A
Major diameter 0.5950 - 0.0060
Pitch diameter 0.5747 - 0.0027
Minor diameter 0.5567 maximum


Can anyone confirm what the chinese rifles have on their muzzle?
