Thanks for watching! I appreciate your feedback. As far as "parts falling out" I have not had this issue, nor do I see how it could happen without sloppy installation. I would sooner blame the technician than the airsoft gun in this case.
As for "wobbliness" of the stock, it is true that the pistol grip can become a weak point in the MB05. To mitigate the problem I drilled a small hole in the grip & have filled the internal empty space with Great Stuff Big Gap Filler (

I have used Great Stuff within other empty parts of the plastic stock to this effect. There may be similar products that will work just as well.
Whatever you choose I'm sure you'll have a great time, dude. Buy it before 4/18 & join us at OP: DOW!
