Yeap....my red one has the right hand popping off problem, and its abit loose so it doesn't hold the gun properly. But i fixed that with a little dab of bluetak on the sides of the joint.
The Red on mine looks alright though.
Another potential problem which I'm not sure if its in all the Red BTs are, the hood doesn't go in all the way into the front. It pops out by a little and there's a little space in between the hood and the engine compartment. It bugs me just a little.
