Hello everyone I need help to upgrade the fps on my weapon g&g CM16, this are the upgrades the weapon already have:

-Mad bull Black Python tight bore inner barrel 6.03mm (407mm)
-Prometheus Neo strike Hop up Chamber
-Prometheus Soft Bucking
-Lonex A-1 motor
-AOE Corrected
-Prometheus ms120
-SHS cylinder type 0

Right now with the prometheus m120 spring my gun is around 380 fps and I want a little bit more, after reading this guide (http://www.airsoftforum.com/board/topic/97249-aeg-upgrading-guide/) (awesome guide) this is the list of the upgrades I'm thinking to buy:

-SHS 8mm bushings (http://www.evike.com/products/46930)
-Prometheus m135 (http://www.evike.com/products/32454)
-Lonex Bearing Spring guide (http://www.evike.com/products/35848)

-Lonex Red Piston (http://www.evike.com/products/37851)

-Guarder Cylinder Head (http://www.evike.com/products/26505)
-Lonex Polycarbonate pistonhead (http://www.evike.com/products/44787)
-Guarder infinite torque gears (http://www.evike.com/products/27212)
(not sure if my stock g&g gears can handle that spring)

I'm open to suggestions, I'm not sure if the gears, piston or piston head are the best choice or if I need to upgrade something else in the gearbox to handle a prometheus m135 spring

thanks in advance!

You are going about it wrong...what is your target FPS with 20g bbs?

 

From there we can assist. Over 70% of the items you listed will not help you get higher FPS. Durability yes...higher fps...no

Hey thats great hahaha I guess im saving 70% of the budget, my target is 450 fps with 0.2 bbs, what do I need to upgrade master?

If you do it right the stock components will be fine for awhile.

 

But, if you are in there any ways.

 

Get a M130 and use the Lonex red piston. You are also using a double bearing system which is not smart, for it will stress your system unnecessarily.

 

Ditch the spring guide with BEARINGs and piston head with BEARINGs. You are fine with the stock one if the posts are metal and a non-bearing piston head is fine, stock.

Add these tweeks in and you should have a 450fps with .20g AEG.

Unless my conversion skills are rusty, M130 comes out to 426fps. Even with good compression, it would be a challenge to hit 450fps.

 

M140 comes out to 459fps, which after the spring settles should end up right at 450fps.

 

The CM gearbox shell probably wont stand up to that for long, even with radiusing and sorbothane.

I need help on figuring out what is necessary if I'm going for a M140 spring, I don't want my gun to be destroyed after a few games with it, so far I would only have to change the gearbox shell, piston and stay with the rest stock parts?

 

or is it just a bad idea to increase that much the fps on a CM platform and leave it with the M120 spring?

my advice, compression, m120, new bucking by maple leaf. all coming to (without tech work) $38.50. parts are widely available everywhere but I buy mine on ebay due to cheap prices on shs parts with free shipping. that will get you about 400-420 fps. not 450. you don't need that much fps unless you are doing a dmr role. which is ridiculous IMO because you can get near same results with a nice flathop, a 400 fps gun, and .28g bbs

I think ill follow your input, I don't actually play in the us, I play in panama (central america) most of the games are mislim jungle style, but between the maple leaf or flathop which one you guys recommend? I WANT to go with .28g bb's thats my goal! because of the game style, vegetation, etc

for now, maple leaf. then when you get more experienced, flathop. and that's great. I live in florida and it's pretty woodsy over here too!
