I got the old nut off okay, with the help of a blowtorch to heat things up, it came off quite nicely,
The question is:
What sort of thread lock, anti-seize goes on the threads of the barrel nut to the receiver?
I am thinking of high heat automotive anti-seize, by maybe Locktite Red ??
How tight to torque the barrel nut to?
I am thinking just enough to route the gas rod through.
This is my first barrel / receiver disassembly - any tips would be appreciated.
Really? A blow torch? WOW! I just use a wrench and the upper vise clamp. ETA: I think I remember someone saying a few MFGs use locktite on their barrel nuts...You may have had one like this...Apologies!
Grease...Moly Grease...I actually found the white paste at a boat shop. They use it to lube and keep corosion off boat props.
Loctite Red? Please don't. The gas tube locks this thing in place. 30 ft lbs is more than enough. I usually end up dialing up 40 ft lbs to gett the next slot for the gas tube...I rarely get to the click.
The specs I believe are as advertised 30-80 ft lbs. It has been noted by builders that the least amount of torque makes the rifle more accurate. I guess I can follow that, but I still like the min setting.
