Just want to confirm: The threads of the SEI adapter work without any issues with the Norinco/Polytech threaded barrel??
 
^^^ what he said , just don't mess up that castle nut I think they are hard to find note that the adapter is held on buy the castle nut but forward of the sight it is threaded to accept standard American .30 cal muzzle devices

The adapter is not threaded, it is splined. You use your existing castle nut to retain it so it will fit Norc or GI barrels.

Cool, thanks dudes...
 
Thanks for all your responses :)

From what I can tell my flash hider and the sights are 1 piece, they cant be separated. So if I was to replace it I would need to find a new front sight as well... 2 pieces, + shipping, maybe duty + gunsmith to connect them as I think my existing flash hider has welds to the barrel. Damn might be close to $300 dollars.
 
I have that same basic part that I took off my norinco if you have troubles with it being a restricted part I could make a deal for mine it is luged and suffered no damage when we broke it loose with a hammer plus the spines are true unlike some Chinese flash hiders !
 
I just bought this, wish me luck and thanks again for all your help!

tavares86,

I have some here if you need the bayonet lugged version. Remember at my Oshawa Clinic you heard them PING? We installed FOUR of them that afternoon?

Remember now? I have some here if you cannot find them. PM Me...

cheers,
Barney
 
Does the SEI naval brake ping? Or is it just the USGI?

I like my pingy rifle, it reminds me why some things are worth pouring hundreds of hours, even if it's just a little noise that makes you happy after you blow up a watermelon

This is pretty much the dogma of owning and customizing a firearm. I'm going to use this quote from now on.
