Powerman Posted January 24, 2013 Report Share Posted January 24, 2013 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. Quote Link to comment Share on other sites More sharing options...
unforgiven Posted January 24, 2013 Report Share Posted January 24, 2013 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.

Rsquared Posted January 24, 2013 Report Share Posted January 24, 2013 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. Quote Link to comment Share on other sites More sharing options...
