When you recieve a NIB AR, whats he deal with cosmoline, i seen a few threads about it a while back but i cant find em. When i get mine is it gonna caked in cosmoline? How do you remove it? What all parts of the gun is it gonna be on?
Hold on while i put my flame resistant suit on
yes i am new so take it easy on me, please
A new AR will not have any cosmoline on it. They use cosmoline on mil surp weapons that have been or will be in storage for a long period of time, getting that shit off is a pain in the ass though
Send it to me. I'll clean all the "cosmoline" and cob webs out of it for you.
Seriously, a patch or two down the barrel with your bore cleaner of choice followed by a dry patch and you should be good to go. A through visual and function check would be a good idea too.
Note: Do not let the hammer fall on bare metal. Use your finger or a hammer block to avoid beating hell out of things
Verify that hammer locks to the rear when pushed back.
Verify that hammer pivots forward when trigger is pressed.
Without releasing the trigger, push the hammer back again and verify that it locks (caught by disconnector).
Releasing the trigger should not cause the hammer to pivot fully forward (caught by trigger).
Hammer will fall when trigger is pressed.
