Upgrading G&G top techs.
 

Hey, so at the end of the year I'm thinking about possibly upgrading my G&G top tech mp5. What would you guys recommend? Do the G&G top techs need upgrading? They come standard with
-6.03mm tightbore barrel

-High-Torque motor

-Silver wiring

-8mm ball bearing, pneumatic blowback gearbox

-Metal internals

Currently it shoots at about 320 FPS. I'd like to bump it upto 375ish (however I CAN'T go over 400), what would need to be done for that and what parts do you recommend?

The top tech Mp5s are one of the easier ones to work on. The AR series is a pain.

Do you want to keep the blowback? If not, then you'll have to modify a standard cylinder a little bit to fit the gearbox... it seems to be a bit short to fit a regular cylinder.

an M100 or 110 spring will put you in the FPS margin you want.


I would recommend not touching it till it breaks... unless there's an area of performance that you're really not happy with.

Definitely want to keep the blowback.

So would you wait to upgrade the spring until something breaks? Do I need to upgrade anything else to handle the spring? Will I notice any decrease in accuracy?

So from what I gather, the top techs are pretty good right out of the box?

My top tech mp5 shot 400 right out of the box. 320 seems a bit low. Is this gun brand new?

Yeah pretty new.

Though G&Gs website states these guns shoot 90-100 m/sec... So
Roughly 330 FPS max.

Did you get it brand new in Canada? None of them should be shooting that low... the ones I sell shoot ~380-390 out of the box.

Are you the first owner? Did you chrono with 0.20g?

I got mine from the USA 3 years ago.

So spring aside, what upgrades would you guys recommend?

None, they're great guns stock, with quality internals.

Great thanks!
