IIRC, this is held in via dimples on a non-threaded barrel and the pins are at least brazed in place if not welded. Is that correct?
Yes. (this message is too short)
Rob,
I don’t think the pins are brazed or welded. I had ADCO remove the brake (as well as some other work) on a ban-era MT6601 barrel. I didn’t see any indication on the barrel or on/inside the brake that the pins were brazed or welded. You can see one of the dimples on the end of the barrel in this picture.
I hope this helps.
Did you pick up a 6400C?
They just put a dollop in the top of the pins. If you grind the tops and yank the whole thing comes off.
Deleted.
Not my gun.
From the picture above it appears that the barrel can be threaded after removal without having to be cut back?
Makes sense that it wouldn’t have to be welded since the barrel wasn’t threaded.
Yes, they can be threaded and a flash suppressor installed.
Why don’t you swap it for a 6920 barrel and sell the 6400 barrel to a ban state?
Not
My
Gun
About a week after the ban expired I had the stupid brake removed from mine and the barrel threaded with an A2 FH put on. It was about $70 cost to get it done. Been that way ever since. Shoots fine.
I have a barrel just like that and have removed the brake… the pins on mine came right out with a punch. The brake wont exactly fall off with the pins removed, it takes some convincing
I had the brake removed and an A2 installed, $100 and it works great.
The better solution is to get a 6920 barrel from Colt and sell off the 6400 barrel. With 6920 uppers selling for $700 direct from Colt now, there is no reason not to do this.
