hi capa 4.3 blow back

i had my hi capa checked and he said that the blow back mechanism or somthing is busted..anyone noe how to fix it??

Get more details, explain (in as best detail) what is going on that makes him say it's busted. That's like saying "My mechanic say's my car is fucked (engine, brakes, body, suspension???????????), anyone know how to fix it?".

Just outline your expereince with it, what it does, what it doesn't do, everything you can suggest. You are askig us to mindread, and we can't do that unless you do your part and inform us. I guess it's kinda like going to the doctor to say you dont' feel good, he asks where does it not feel good, you say you don't know cuz you never went to medical school, so HE should know just by looking around................. ONLINE!

k so far what i noe is..
1. when i fire the gun the slide doesnt go back all the way
2. when i load bb's the piston (i think..well the thing were the piston head is in) will go back slowly
3. in order to fire i have to push the slide forward
4.the piston gets retarded when the mag is in

You need a new o-ring/piston head.

Whoa, I thought the new hicapa 4.3's dont have the O-ring problem anymore?

Yea, judging by what you said, harleyb is right, you o-ring is blown out. Either get a new one at canadian tire, Tania Koba piston cup set, or the various other aftermarket parts directed to fix this problem.

Sounds like a severe lack of maintenance, too. Do you ever lubricate that gun?

i just got the gun, only like 3rd time playing with it
