@Mr.Hitman: my slide is from airsoft surgeon.its pretty good actually.the problem is more from my lack of experience and poor selection of parts.

@ILLusion:guarder outer barrel really is one piece of crap.im ordering a SD shamber.but in the mean time im gonna use tm plastic outer,will it be okay? and since it need quite some force to insert the hopup to the chamber,any suggetion on how to remove my hopup&inner from the guarder chamber safely?thanks

the sd grips fits just fine,and you're right,i have to file the hole for mag catch,grip safety and trigger too for all the parts to fit
