WE G39 RAS - minus Matasz

[halifax1977]

Hi all,

I can't figure this out for the life of me.

I have a WE G39RAS.

I can zero to point of aim with a reddot or other scope but notwith the iron sights.
It shoots about two feet high of the target at 30 feet with no hopup using .25's I not sure of the the FPS but it is a we fror the candian markets box says 430fps.


Any suggestions?


Thanks

can you see your bb arching up?

Like Ross said, make sure the BBs aren't arcing upwards. If they are, and the hop isn't the issue, then you might have to put in an NPAS to lower the velocity.

There's also the chance that your sights are off-center. Check those.

Gentlemen we has RasMtazzzz. I found the hopup not assembled correctly, it eould spin but not change. On reassembly hopup is adjustable and lowered rear sight to lowest and it accurate on battle sights and a tack driver on the target 1.5 inch group of 5 at 45 feet.i.

Thanks All

This ones is solved

Speaking of the 39, I recently installed an npas in mine, found that it jams up alot at lower fps and the rate of fire drops quite a bit. Is that normal?

Hi,

Its a guess but lower fps might need a weaker recoil spring if you now prroviding less recoil on a spring meant to recoil at about440 fps to 350 I could see cycling problems arising. However its just an opion iy would begreat to hear from someone with more build repair experence :-)

Lower FPS = less gas = lower cycling speed.

Thanks for the help guys. Where would I look for a weaker recoil spring?
