uhh ya i have no idea wat happened. I was playing on saturday and i grab my m733 by the handguards and the gun just slides off... everything from the handguards up came off with the exception of the barrel. And when i say barrel i mean the bare barrel, the black sheathing that normally covers the barrel came off too. I tried putting it back together and everything fits, but the problem is that the second i pick it up it slides off again. Anyone know how to fix this i don't want to pay someone to open my gun up again...
In the picture what is circled in red is what came off
