My friends Stag was purchased new. The castle nut was unstaked. About 500 rounds in, at the range, the castle nut came loose. The extention backed out and the bcg became stuck halfway into the tube after the detent decided to pop out as the bcg was cycling out of battery.
Toom me about 15 mins to figure out the problem. Another 45 mins of asking for help and scrounging for tools. Not fun. Annoying as hell. If that happened in class id be embarassed and pissed.
All my boys are staked. Blue loctitie too if I even had to change the extension.
