Famas Feeding Problem

Sadiztix · July 25th, 2005, 22:34

ok
i'm currently using 20's in this famas
wich has
tons of upgrades in the mechbox

but it is jamming and misfeeding in the tightbore
i think it's a hopup problem
but i'm not that knowledgeable with the hopup bucking and all that jazz
the gun turns over the bb shoots out at a low velocity and sometimes more than one on semi
before it jams

any help would be much appreciated

Be more precise; what upgrades?

590mm 6.03mm prometheus tightbore
PDI 140%
polycarb piston
aluminum piston head
new loading nozzle
bushings
aluminum cylinder

I think that's all of it...

Best guess; badly installed (or used) hopup. Bad gear timing (not too likely). Barrel is too tight or dirty.

I bet on the hopup being badly installed or adjusted.

actually i didn't set the tappet plate right
and that was the issue

Curious, since i have the same mechbox setup... how much improvement did the tightbore deliver? Cuz I was getting pretty bad dispersion stock, and it cleaned up a lot when I got some extra power in the mechbox so I never bothered with a tightbore, but always wondered if I should hehe

the tightbore is awesomeness actually the length of this one is the psg1 wich we used a k2 1 piece solid steel cylinder from den trinity, it kicks out currently average of 360-367fps with a pdi140% (weakend up from previous use in a g3) the shot grouping is redicoulously accurate aswell it's the prometheus 6.03 tightbore stainless steel model 590mm in length
