My new m4 build

[gezer]

Hi guys, I was thinking of building up a new m4.

And I've decided to give it a go.

I will sell a few things and should get around £500 to spend in all

I want to achieve around 26-30rps with either 7.4v or 11.1v (not sure)

So here's what I was thinking

Internals

BTC spectre/chimera

Prowin split mechbox (with the hop built in)

Siegtek 14:1 ratio

Terminusx bushings

Lonex a2 Titan motor (siegetek pinion)

Shims of some brand (is there any difference between brands)

Lonex blue/red piston (not sure)

Not really sure on cylinder, cylinder head, piston head, spring guide or spring (I now it'll be roughly m90-100)

R hop and m nub

Prommy barrel

Externals

G&p body with crane stock

Madbull ris

Magpull trigger guard and grip

Pmags

What changes would you do to this set up?

And advice on the things I'm not sure on would be great

save yourself a load of time and hassle with internals and just buy a Marui CRW High Cycle, stick a 7.4v LiPo in it and you've got your ROF sorted. They're pretty economical too!

Cant go wrong with a TM high cycle mate

Also get a mosfet! when using lipo 11.1 then you will have burns on the triggers !!! So get a mosfet af priority one! Don't have to be a fancy programable one, a simple mosfet swithc can do the job just fine
