:cry: :cry:


I just shot it off for a bit of fun, it was working fine, until the bb's shot out only about 15 20 feet before they hit the grass, then they basically just poured out of the tube, I have only a basic upgrade on it, tightbore, bushings, m120 spring, spring guide. that is it, it doesnt sound like the gears are stripped, I dont know, I will take it in when I get my AK back though.

Sorry man that sucks, I JUST got my M733 working tonite too if it makes you feel any better. Hope it's nothing too expensive like mine was.

Oh gee, thanks nick, now I will be extra careful with my AK, ****, I might as well leave most of my **** stock, unless it was just a flaw in the one I got or something.

Hmm, I thought it could be jammed, I never thought of that, so I put the hop up all the way off, and when I proceeded to do so, it seemed very loose, could I be onto something? I jammed the rod down there and nothing.

ever pull it apart? If the hopup feels loose, it could be that the bucking got shredded.

what does it sound like when you pull the trigger? does anything happen?

if the is shreded it will still shoot more than 20ft, I would guess that the piston head probably removed it'self. This happened once on RTO's PDW withe the stock piston and head and a systema m100.

Same symptoms and all.

air nozzle. if the piston head let loose it would jam up and lock.

If the what shreaded?

The piston head on my gun.. oh boy, yes. That was glorious, BUT it did not shoot, it locked up. It went from shooting out normall one shot to the next shot... NOTHING! ha ha ha...

Sorry to hear Vig.

if the hopup bucking shredded. Its the rubber grommet that is on the hopup that makes it do the voodoo it...uh..do.

Yeah I had the same thing Happen with my TM M733, I had a M100 in there as well. I used thread lock and SNAP! instant jam. I didn't touch my gun for a week after that (I was too mad) >:( .

ALso, when it did shoot that 25 feet, it shot out 2 or 3 bbs at once.

i love when people that have no idea post. its an airnozzle/tappet plate problem.

It sounds like you blew the welds on the battery transfer manifold. ;)

22 Nov 05, 02:53 PM
Ha ha ha, yea, how much will it cost for the air nozzle, like 10 or 12 bucks? Should I just like replace most of the stock stuff then, or just the air nozzle and tappet plate?

Timmay
22 Nov 05, 03:06 PM
i can tell you when i look at it. its either the nozzle, plate, both, or it came off the plate.

I believe that the problem is in your fuel pump. Or it might be a problem with the hard drive.

Don't listen to timmay he's full of ****, everyone know that when that happens in Nov. it's the barrel. I KNOW you bent your barrel, you need to clamp it in a vise (Hard) so as to straighten it.That or you lost your airseal in your cylinder, to fix it I sugjest a good 2 part epoxy to get a tight seal around the edges of the piston, and then also plug the gaps between your gear shafts and the bearings, alot of FPS is lost due to sloppy air management.

Um, putting the barrel in there made it worse, now its flat, and the only thing that can go through is water. I guess I can use it as a bug sprayer.

Did you try washing the interanls with soapy brine water and then letting it air dry? if not, give it a try and I am sure the gun will work much better.

Vigilante
22 Nov 05, 04:45 PM
Well, I thought if I threw it in the dirt, and put some water on it, so it turned into mud and took a bath with it, it might feel better..




but on a serious note, it probably is the air seal nozzle or w/e timmay said, I will bring it in soon.

You guys are all crazy its gotta be your Flux-Capacitor. Just walk outside during a thunderstorm and have it get struck by lightning, then traveling back in time you can go back to the nite before it broke steal all your batteries and prevent yourself from ever firing it.

Just make sure you don't run into your "other" self. ;)

This pertains to me as well, but don't post useless crap that has nothing to do with the topic unless it deals with you.


With that said, I am going to listen to my own advice.
