firing problem for upgraded m4

[chinese_gunman]

ok..so here's the problem...i have a systema complete mech box (m120), guarder metal body, one piece guarder plastic hopup, madbull innerbarrel, madbull hopup rubber, and a G&P m4 CQB/R complete front end.

when i fire a .2 bb from the gun...it jams..now when i open up the m4, the end of my aluminum innerbarrel got bent....and the end of the hopup rubber - where the mech box air nozzel is suppose to hit - rips...

i thought maybe the plastic hopup was crap and put in a metal one...same problem

then i thought maybe the air nozzel was hitting the hopup and innerbarrel cauzing it to bend but after inspecting the mech box...there wasn't any signs of damage...the bb would be jamed inside the hopup - visible in the magwell-

i don't know if the hopup and innerbarrel are too close to the mech box or the barrel is out of line...eitherway..i need help to solve this problem...after spending at least a grand on this gun...i don't want it to be ruined. Has anyone experienced this problem?

*update: so i put the an original tm barrel in..and just the outer barrel...it fired perfectly...but as soon as i put the RAS unit on..the same problem happened

It sounds like there's an issue with the way the RAS mounts to the body, throwing the hopup unit out of alignment.

yea i figured that much...maybe i put the ras unit too far and its causing the hopup and innerbarrel to move weird.....but...i've got new rubbers on the way and hopefully it'll work
