M4 Mws (Mk18) FPS Upgrade

[tommy turner]

hi all.... i have purchased the m4 mws (mk18 version) from a site called impulse in japan, -- i am constant player of CQB airsoft at my local bristol airsoft i usually go once a week

my pistols are 330-350 fps, my shotgun is 350 fps, unfortunately the MWS is only 280 fps - the difference in 70 fps is huge- especially outdoors it makes me not want to even try to take it outdoors but the gun is so damn nice and almost perfect..

i understand physics of gas rifles and believe that if i increase the barrel length of my rifle, and also reduce the barrel width to 6.01 mm i will get increased fps, am i correct?

if so have anybody got any idea where i can buy such a barrel?? thanks alot

You are correct, a longer inner barrel in a GBBR will increase fps / power . You may find that there is an alternative nozle available too, Japan has very strict power limits, there may ba a 'rest of the world ' option 

 

What length is the inner barrel now ?

Stop using duster gas and use Predator Ultra Gas
