    I have installed 3 UBRs. All 3 were tightened by hand via a large flat bladed screw driver. I have not experienced any issues with the receiver tube screw working it's way loose. The most recent UBR stock came from MagPul with quite a large amount of dried blue loctite pre applied on the receiver tube screw.

    Mine came like this as well. I used a large screwdriver with some pliers for extra leverage.

    I was referring to putting Loc-tite on the threads of the actual receiver extension. I used it on my screws.

    If you have ever had to break a lower receiver extension loose that has been Loc-tited you'll understand what I mean.

    I wasn't talking about putting loctite on the extension, just the screw.

    I would hazard a guess that gas-key screws and receiver extension nuts are staked in place because when you are in the middle of a 72-hour or longer mission, having your rifle go tango uniform isn't going to be an acceptable excuse. In civilian life, you can notice the nut becoming loose and you can get it fixed that day, or at most the next morning. That doesn't happen often during conflicts. Nuts and screws are staked in anticipation of a worst case scenario.

    Most of us probably have a set of hex wrenches, screwdrivers, maybe some punches, an extension nut wrench within either an arms reach or at home. That's maintenance prohibited at the user level in the military.
