Hey guys, I have a G&G M4 pneumatic blowback. I'm looking to ugrade my spring, (I'm not sure what it is I have that I'm going to put in, but it's most likely an M120) so to do that I have to also upgrade my internals. What my friend told me I need is the following;

New piston and piston head (he said piston would be better with metal teeth)
New metal cylinder head
Metal Hop-up
and new gears.

Can anyone direct me to the right parts to order? I don't have a huge budget, and I'd prefer if they were from airsoftparts.ca or airsoftdepot.ca.
Thanks!
