Now if things go to plan it will undergo a big change between now and Fulda Gap.

Now, as you may know this gun shoots like 400+ fps out of the box. Im ok with that but am slightly downgrading to increase reliablity. Ive already added a 393mm barrel that is run through the GemTech Halo.

Internally ive got coming:

Metal Hop Unit (need this for realiability as for the body change)
ARS Sorbo Pads- These things are supposed to be amazing. Dampens the impact, quiets down the mechbox noise, and according to all the reviews they claim you can run a 150 spring on stock gears and stock mech box shell.
Downgrading from the stock M120 spring to a M110
Switched to Deans Connectors
Rewiring it to the rear
G&P Explosive Piston Head
Replacing the piston head o-ring with a Viton X-Ring
Ball Bearing Spring Guide
Guarder PolyCarb Piston
Reinforced steel gears- only for realiability not upgrading for speed or power
Sector Gear Chip
Replacing stock shims and bushings with CA shims and Element 6mm bearing bushings.

There are a few more mods to come as well, but ill post them once ive either completed them or at least ordered the parts.
