Misc ??? Buffer tube, gas block, break in.

[Powerman]

So do you guys lock tight your buffer tubes? I have a castle nut, but was surprised there was not some sort of pin or something to lock it in place. Or is tightening the castle nut all that is needed? Oh... 6 pos stock and magpul.

I mocked up my upper, was waiting to put it together. I went to put the gas block on but it is quite tight. I did nt expect it to be THAT tight. Just making sure thats right. It's a DPMS block and FA barrel.

Are the any good write up for safety checks, lubing it up and taking it out for the first time? I could not find anything looking around. Break in stuff. I also do not know how to break in my Fulton Armory SS hvy Critrian barrel. FA web site has been down for a while.

You could just tighten castel nut,or if you got a spring loaded center punch or any center punch hit the threads once to keep the nut from backing off.That's for collapsable stocks,A2 has a screw at the end of butstock with blue thread locker.

Hell, no.

You stake the lockring in place.

Haven't had any problem with any of mine. And I shoot the hell out of them. My goto AR-10 carbine has had a couple thousand rounds without any issue.
