So I'm finally assembling my AR tomorrow as I wait on my bolt. During assembly, is it beneficial or recommended to put some anti-seize on the extension so if I ever swap barrels it's not stuck in the reciever with carbon build up? Or does the extension get too hot for anti-seize?
The other thing is that my barrel (Rainier Arms match) fits really (really) tight into my upper receiver (Mega billet). Extension gets about half way in on it's own before some bit of force is needed to get it the rest of the way. Not sure how much force as I've not wanted to not be able to get it back out should anti-seize be recommended.
Thanks in advance for the feedback.
