G&G TGM Q6 (MP5 SD6) Upgrade Question

[ash3751]

Good Morning all,

As the title says I have a G&G TGM Q6 which is the top tech MP5 SD6 variant. Im looking to upgrade this as its currently shooting around 295-300 fps mark. I was thinking just replacing the piston, piston head, cylinder head with sorbo pad to correct AOE and then get an O ring air nozzle upgrade.

Keeping the stock gears and motor hoping these upgrades above will be enough to up the fps to around the 340 mark?

I was also thinking about flat hop with a prommy purple bucking and firefly flat nub?

I use .25's but obviously want it close to the 350 mark on the .20's so its chrono safe if a site uses .20's for chrono testing.

Cheers,
