Cleaned up the understock with some guner we had on hand. Seemed to work pretty good. Took a lot of paper towels and scrubbing, not too much scrubbing though. There was a lot of dirt and grime built up in this thing. Really hard to get behind the release button buuuut finally got rid of the crunching sound when opening and closing it. Ran some alcohol thru it as well. Now I'm waiting for some Super Lube. Next... how the hell to get it attached.. Sent from my SM-J700T using Tapatalk
