What should I do to my classic army M15A4.

Hey I have this horrible range and sounding M15A4 but it shoots. Dose anybody have any upgrades I should get.

List
tight boar barrel
New hop up Don't know witch one i should buy.
m130 spring

Yea thats all i have. Have any other parts I should get.The gearbox is a Classic Army gearbox no upgrades.

Get a Madbull blue hop up bucking. Ask Rhino about the other stuff. he knows

Okay cool I will.

There is some controversy as to whether Tight bore barrels actually do anything. Maybe you should put that upgrade on hold for right now and focus on some other things?

Maybe you dont need a new hop up as much as you need just a bucking? It will save you some money. Try a madbull blue bucking.

If your gun is making a weird noise might i suggest getting a better motor (A magnum motor maybe?) and some new gears? A new piston probably couldnt hurt either.

Make sure you gearbox is properly shimmed and you have good bushings.

Any suggestions for the gears and piston. Yea i Think i did the shimming right.

The CA motor with the M130 probably won't do so hot. I'd get a Matrix Magnum.

I decided to hook it up to a lipo not a good idea. 4 teeth broke off the spur gear and 2 teeth broke off the Bevel Gear. I am thinking of getting Airdog elite piston with Systema Steel Piston Head, For gears Guarder Infinite Torque-Up Gear Set.Bearings Bushings,Guarder 6mm Super Bearing Metal Bushing.Spring Prometheus Non-Liner Irragular Pitch. Should i get m150 or m135 you vote.

neither CA GB's are junk! stick with a m120 or better yet i would recomend selling your ca and getting a kwa or G&G.

I would like to sell it but i think im going to upgrade it first and see how it goes this is my second gun I have a G&P magpul zombie killer m4. This is just a project to turn it into a sniper. I don't think i would have any luck selling just the body of the gun.

The G&G I bought from Blaze runs with a Matrix Magnum and a 11.1 Lipo with a stock G&G piston. I'm surprised that it still not broken or looked like it chipped a tooth.

Never mind close this subject I am just going to fuse both my guns together. You know use some parts from one and some parts from the other.Thanks for the help anyways.

I got the same gun as you. The first thing I did to it was add a new hop up and bucking, along with a TBB since the stock CA hop up was poor in performance. With a new spring, you also have to have a new motor and probably a higher voltage battery to pull it, among many parts in the gearbox.
