Need Help! upgrading M4A1 CQBR

    hey guys,
    I am currently trying to decide on what exactly to do with my CyberGun Colt M4A1 CQBR. its about 2 years old only been used at airsoft days twice and other than that just used to shoot cans etc in back yard.
    Its basically brand new no scratches marks of problems etc...

    One thing i am sure on is the MagPul MOE kit in Dark earth of Foliage green.

    BUT

    the main part and this is really the most important i guess is what to do with the internals. i have very limited experience with this and my rational behind upgrading this gun stems from wanting to guy another gun but then realising that I can just upgrade my existing one.
    she is currently shooting 290FPS fully greased up which i am happy with but would like to bring alot closer to 328~
    I also noticed that it was drilled to reduced FPS and suprisingly enough the shop that i bought it from is a really really well known shop with an amzing rep so i wont name any names on the fact that it was 2 years ago etc...

    Any ideas for me guys?:confused:

    thanks.

    i know the shop and they still doing that.
    anyway first upgrade the inner barrel and hopup unit, go for the madbull ones they are the dogs man vegatables, this will increase the FPS by about 20 which is as close to the limit as u may get.

    also checkout my facebook page for info on upgrading

    "I also noticed that it was drilled to reduced FPS"


    try cover the hole, i used a clear bit of strong plastic, i roughed it up a bit with sandpaper and super glued it over the hole, plus if its to high just remove it.

    keep in mind that the change in weather also affects the performance of the AEG, just a thought.

    hi, i am also upgrading an m4cqbr. if i was in your shoes i would replace the cylinder get a tightbore madbull barrel and hop up also open up the gun and check it is well shimmed if you wanted you could do what i did and changed the internals all to ultimate ones she fires unreal and very crisp. I also rewired to the front and fitted an magpul conversionkit in dark earth
