I recently bought this awesome little beast : the G&P Baby Monster
http://shop.ehobbyasia.com/gandp-baby-monster.html
The hop-up does not seem to be very good so I would like to change the rubber and check everything.
I am wondering where should I start to open this thing and reach the hop-up. I want to disassemble it as little as possible.
Do I look for videos for a regular M4 (since it'a basically a short M4) or should I do it differently?
Thanks!
