tightbore barrel fps increase...?

[FireShark03]

hi everyone,

i have recently bought a new gun which i wanted to be around 340-345 fps which it does. But i forgot to take into account i wanted a tightbore aswell.
I was wondering what sort of increase in fps would say a 6.03/6.04 barrel from a G&P standard barrel (think its a 6.08, but no proof)

any info would be most appreciated.

regards,
Aaron

Approx 10/15 fps.

Your mileage may vary.

Find out what bore it is first.
I didn't notice any fps change but grouping was better.

Usually 0-10.

on a m100 with a 300ish mm 6.01 madbull python barrel with very good airseal i was pushing 550FPS. with a insane ROF, without trying.

all chinese parts with element hop, and a G&P m120, and a m100 :P and ofc the barrel.

its 450 sorry. typeo ..oh i forgot to mention i also sealed the hop-up to the gearbox and ptfe taped any possible air leeks.. might have gone a little OCD. either way it can be done, but its a pain in the ass, as you got to go back and start removing bits to let air out... and hows this for f*&^ up... 100fps on a m170, 2 days work .. i want to cry, anyway im off to bed ;(

I changed the barrel on a stock TM P90 to a 6.03, and the fps went up by about 8.
