Ran into the semi lock up problem for the first time this past weekend. Now that I think about it, I think I remember it happening occasionally to my CA36. Must be a v3 thing.
The little plastic square cap thing on top of the gun came off. Some super glue later, good as new. My only real complaint is that the stock has a little wobble to it due to imperfect match between the plate and the rear of the gun; the stock bolt return spring is also on the weak side and can rattle.
Other than that, boy am I smitten with this thing. I originally traded for it so I can sell it and fund a 4.3, but instead I'm finding myself buying a new battery for it and everything.
