As I'm saving for a bullpup now, seeing there is some interest, but not enough I've decided to bump it up a bit.

So now You get and ultimate combo of M4 and M203!

Both ICS

M203 comes with shell that will cover Your opponent with around 90 bb's!

Has new o'rnig and spring

M4 is a split gearbox, full metal, Proline ICS 22 RIS with functional forward assist! (Releases spring tension prolonging its lifespan)

Really easy to work on

Rewired- 16awg silver coated silicone wire on Deans

Front rail cussioned with abs shims to eliminate wobble

Upgraded top;

-TM piston

-Lonex tappet plate

-Lonex 8port piston head 

-TM polished cylinder

-SHS double o'ring cnc head

-Lonex o'ring nozzle

Mildly upgraded bottom;

-Rewired

-Lonex delayer chip

Mildly upgraded front;

-Element hop chamber (had to be filled down to fit)

-Guarder bucking

-Guarder nub

Shoots nice, around 345 on 0.20g, good rate of fire, doesn't like high caps (tend to miss feed on high caps) I recon its down to hop unit as original (£15) fell apart , so cheap and easy fix.

Collection can be arranged via courier on buyers responsibility, so if You loose it outside my driveway don't come back crying.

Also I recommend collecting in person, so You can test it, see old parts that have been replaced and have a cuppa with fellow airsofter.
