looking to get some upgrades for my m4 to get as much range/accuracy as possible. want to get it shooting about 380-400.

Get your velocity up, and a prometheus barrel. Then use .27's.

im already going at 380 and i got a systema m16 barrel thats completely flush with the end my m4. im rocking a standard 14.5 inch barrel and a silencer.

Did you install an M16 cylinder at the same time? What brand barrel are you using? What weight and brand BB's? Cleaned your barrel in a while?

no i didnt install a cylinder. and i had someone chek my gun out and they said i might have a gg gearbox instled. i bought it used. im rocking a ca outer barrel and systema inner barrel. bbs i use toytec .25 usually.

KM TN inner barrel + Guarder Hop Bucking (clear) + M4 cylinder + good seal on/in piston head assembly. gtg.

yeah. well externally my rifle is pretty much done im keepeing it the way it is. but like you said the g.box is not the best of quality and im perfectly fine with swapping out for better parts. ill definently look into dropping the fps to around 350-370 as u guys reccomended.

cylinder maybe, but the compression is good in there, prehaps a stock TM one would be sufficent, piston nah still has at least 9k rounds left on it, playing hard that is, i mean 1k bb burst LOL. gears, and bushings more than likely get it running a little more smoothly as well.

ok. well cylinder i figured i would need to replace. ill look into changing out the gears/bushings soon.
