Airsoft Canada - View Single Post - C9A1 project

Hello !

My latest custom, the canadian minimi, aka the C9A1

The base is the M249 A&K mod 1, that is with european furnitures, skeleton stock, fixed barrel handle et top cover without rail

My first task was to take the beast totally apart to spot the rust on the steel parts (A&K quality being what it is...)

I kept nothing from the stock gearbox except the shell and the tapet plate. You need to reuse that tappet plate since it is shaped to give clearance to the nozzle. A standard M4 nozzle can then be used. If you wish to change the tappet plate, then you'll need a delayer on the gear to give sufficient rear movement to the nozzle when loading BBs.

Once degreased, the gearbox has been painted gloss deep blue. Totally unecessary, therefore mandatory...

I did not keep the A&K internals since:
1) gears were crooked
2) cylinder, cylinder head & nozzle are Bore-up and shitty
3) piston body and piston head were plastic with no compression
4) microswitch isn't the best around

I did some shopping

1) fast G&P motor

2) SHS gears (these are gorgeous and affordables)

3) Pneumatic set from Army Action (the best parts i ever used) and the piston body Deepfire with full metal teeth

4) Selfmade wiring with Mosfet (active breaking) and top quality Swiss made microswitch

The idea behind the set is to give a decent RoF without having parts breaking under stress

All parts are assembled then it is time to make the C9A1

First task was to create the rail with the tombstone backup sight :

Then rework the gas block by
1) creating the parts housed inside the block
2) repaint the block to create the illusion of the anodised grey found on the RS

Then the C9A1 does not have the US style take down pin. I created a new pin and lock then parkerized the pin :

I created a battery compartiment in the ammobox. A cut out in the feed ramp allows the mains to enter discretly the gun. The dean connectors fits nicely in front of the gearbox.

Other improvments are

1) painting the fireselector's red ring

2) buying the steel parts set from Classic Army and the Classic Army Hop-up block

Here's the final result with the Elcan sight and the deactivated 5.56mm rounds

Is it ready ?

Not totally. Missing still are :

1) C9 sling
2) C9 front sight (eared)
3) C9 skeleton stock handle
4) US style outer barrel with M4 flash hider (ordered)

If anyone knows a source for the RS sling, sight and handle, please PM me !

Thanks !
