Otherwise Ill have to go through brownells, ITAR, and ugggh paperwork. Both the ITAR stuff and the Canadian IIC paperwork as well.
Adjustable gas "plugs" are only availlable from U.S.
As for gas cylinder unitizing.... There's only one guy I know that has offered that service and done right every time![]()
Not to hijack but would the SEI gas block be the same specs a a USGI gas block and would it fit a Chinese barrel
Nope![]()
The vast majority of aftermarket products for a gas lock sight are made for the U.S. Barrel thread dimensions based on the USGI M14 drawings.
Chinese barrel threads are metric and not compatable with the above mentioned items.
That said it is possible to force thread a usgi or equiv castlenut or direct connect muzzle device like the SEI Vortex to chinese muzzle thread.
But the gas lock threads are no where near compatable.
Dlask Arms is currently the only manufacturer of a gas lock sight that fits chinese barrels.
What would be really really cool is if we could convince SEI to do a dedicated run of chinese threaded gas lock front sights....
Is that guy still doing it or is he retired?![]()
would SEI or any of the ameracin gas cylinders work the same as a Springfield gas cylinder for the above mentioned set up?
Absolutely, springfield, SEI, LRB, usgi, ect , same![]()
Thomas,
What's the difference between the GI and Norc gas piston, the diameter? Reason I ask is I have been using a Norc in my GI gas cylinder on my H+R parts/Norc receiver rifle without issue for a long time, I now have a US made (I think) commercial piston that I noticed does the tilt test about the same, though it is more polished. I have another GI system going on an all Norc gun and the Norc piston is staying in it as well, it has quite a bit more 'suction' when moving the piston and comes out with a vacuum type resistance, though it is free and doesn't bind and passes the tilt test, it is just much slower than the commercial piston in the other GI system.
