Grease on the buffer tube

[Climberman]

Here's a question to all the home builders out there. Do you put aeroshell or some other grease on your buffer tube threads and/or the castlenut threads when assembling an AR lower?

I don't use any lube at all on buffer tubes or castle nuts. I've never had any issues.

i put blue loctite on mine, and usually never stake em.

I don't think it would hurt anything to put it on the threads. I like Lucas Oil Marine grease from Lowes hardware for all my gun grease needs.

I’ve built a couple before without using it and didn’t have any issues, but I recently bought some aeroshell to use in my future builds. Per mil spec you’re suppose to use it and it’s really cheap, so I figured I may as well get some and use it from now on.

 

[JBoyette]

Nope but i polish the inside.

He's taking about the threads of the reciever extension/ buffer tube it would seem. No. Do not put grease on those threads. No need. Either stake the castle nut or apply loctite.

No grease. I don’t stake or loctite them either and never had one loosen on me.

No grease. I don’t stake or loctite them either and never had one loosen on me.

Same here. Never had a problem.

I stake the castle nut with a cheap ass $3.00 spring loaded punch from harbor freight.
