  1. Would be better if the other guy would stop chiming in. Annoying voice too, All he did was help lose my train of thought watching you do the assembly/ disassembly. One question : Should the bolt be forward sticking out of the carrier or pushed into the carrier when inserting the firing pin and pin retainer?

  2. I use Krytox grease on mine. Light coat of that stuff goes a long way. Tube I have retails at 1800 bucks luckily I worked for Dupont and knew a guy who worked at the Krytox unit. Shit is amazing wheel bearing NEVER ware out any metal to metal contact becomes nonexistent.

  3. Unload your rifle of all ammo, and Magazine…TRIPLE CHECK to make certain,if ..the carrier group is not going into the receiver ..make sure to twist the (cam pin) forward ..which will extend your bolt out to about an inch..then re-insert the (BCG) into the receiver..should have no issues..then function check safety, and fire, ..just like the video is showing here…

  4. Why doesn't anyone say which way the inner bolt should be turned when you put it back in? Since you can spin it around there are two possibilities that allow you to push the pin in. The little ejector sits at a completely different angle though.
