I recently picked up a used ICS M16 (Thanks again, Psycho). As I was fully aware at the time of purchase, the gun was non-functioning. The primary reason for this was a stripped spur gear. Due to this, I decided to make multiple inexpensive upgrades while replacing the gears. Unfortunately, after I had the rifle fully assembled, the tappet plate would not properly cycle. It appears as if the tappet plate will start in the forward position (fully seated into the hop-up unit), but after the first shot the nozzle will not return to this position. My first thought was that the tappet was binding between the sector gear and the gearbox shell; however, when i close the gearbox (before firing it) i'm able to easily push the nozzle in and the spring easily pushes it back out. Additionally, it seems like every time I open the rifle, the gears are facing up which is pulling back the tappet plate. My first thought was that I was dealing with over-spin; however, that seems highly unlikely on such a strong spring with a stock motor. I've scoured the internet and I have not been able to find this specific issue. My part list is below. Gears: ZCI 13:1 Motor: ICS 3000 Mosfet: Nukefet Battery: 3000mah 7.4V (20C) (also tried 1000 mah 11.1v 20C) Spring: Guarder M120 (also tried stock spring) Cut-Off Lever: Stock (I assume) ARL: ICS (stock) Tappet Plate: SHS V2 Nozzel: SHS AK (long) Cylinder Head: SHS V2

I was looking at upgrading my stock G&G combat machine for durability, I am looking for about 350-400 fps also (stock) and keep about the same rof For people that dont have an idea of the internals of the CM series, I will give you a brief rundown 1 peice GR-16 plastic hop-up with green bucking and 6.07 363mm barrel ( still pretty good range) 8mm bushings, m100 spring, metal spring guide, blue cylinder, poly piston and piston head, pretty strong tappet plate, I dont know much about the motor, it is not labeled, gearbox shell is reinforced, and the gears are pretty nice quality. Any ideas for durability upgrades shooting mostly semi-auto?

SOLD! Thanks for looking! RULES: I do not ship first. Do NOT make offers on these items. The prices are already reasonable. Prices include economy shipping. A surcharge will be added for Priority Mail, UPS Ground, or FedEx shipping. Payment can be made through PayPal or money order. I will consider all trades. If you have any questions at all, please feel free to ask. I got myself a pretty little G&P to house my P* and I don't have a need for these. I chronographed the gun with the stock barrel group at 415 FPS w/0.20g as soon as I got it so you may need to have it downgraded before you use it. It hasn't been opened at all; just test fired for 4 seconds and removed from the gun. I removed the baby Deans connectors that came with it and soldered on some real Deans connectors for real men. Asking $90 shipped for it. I can do the following things for an additional fee: Downgrade to <400 FPS: $15.00 Downgrade to <350 FPS: $15.00 Install Simplex Basic MOSFET Unit and lower-than-low-resistance wiring: $30.00 (MOSFET included in price) Re-shim, re-grease, adjust angle of engagement, install sorbothane pad, and round corners of cylinder windows to prevent fractures: $35.00 Thanks for looking!
