minimag won't fire... with video.

[Boltaction]

Hey guys. my mini is having some issues. I bought it back in 02', and could'nt get the level 10 working at all. pretty much put it away until a few weeks ago. was'nt working (just like i left it) so i took it apart, lubed it up and messed with the level 10 some more, still would'nt work. someone on PBN said it was the old regulator piston was'nt working with the new level 10. So i ordered up a new piston and parts kit from AGD. installed new piston and the gun is at least fully pressurizing the trigger now, but will not fire. It seems to me the the trigger rod needs adjusting or the on/off has issues. all the on/off o-rings are present and accounted for, and in perfect shape. I've tried 3 different trigger frames (including the stock one) 2 different body rails and 2 different main bodies. nothing works. Any help would be greatly appreciated.

Have you tried the shorter springs that come with the lvl10? Too long/strong of a spring can keep your gun from firing.

[Boltaction]

yeah i tried evry spring in the kit and the stock one.

[reckid1986]

it fires fine with the lvl 7 in it?

try turning up the velocity...

[Boltaction]

just tried the level 7 and it almost works. leaks pretty bad down the barrel and im getting the sprinkler effect (i think thats the on/off right?) heres the vid with the L7.

thanks for lookin!

from that video there is a leak in the on/off, probably the teflon oring. Change it and oil it good. It still seems like the velocity is too low, maybe something could be blocking air flow so check the hoses and fittings make sure nothing is blocking it in them. Try screwing the tank directly into the vert asa.

It sounds like its low on air or low pressure input.Even though its leaking it should still fire with a loud pop. Since your useing a CO2 tank. I would try to check the pressure input to the valve. I see your useing a simple screw in ASA that pushs the pin in on the tank valve. It might not be openeing the pin valve in the tank enough. Maybe try removing the Expansion chamber and screwiing the tank into the vertical ASA to see if it works with that one.

[Boltaction]

well i just got my HP tanks back from hydro so ill hopefully get em filled tommarow and try with that.

with the CO2 going directly into the vert, it leaks instantly, stops and sprinkles with trigger held. no fire.

ill update this thread tommarow.

thanks for the input. really appreciated.

all right heres the deal. replaced on/off teflon o-ring and tefloned the steel braid from the vert. adaptor to the valve. no leaks now! the CO2 tank was pretty much dead empty from use last weekend and all the swapping on and off the gun. still was'nt shooting but when i took it off the gun and depressed the pin it leaked out in about 3 seconds. so who knows, maybe a full tank will get this thing going before the weekend games.

I was looking inside the powertube with my light and noticed there was some dirt/residue in there. anychance this could be hampering the operation of the gun? its obviously a newer valve so i cant take the top off to clean it out. what are my options?

thanks again.

pipe cleaners work good for cleaning out the powertube. chances are it was just because you were low on air, once you get it working with the lvl 7 it should be easy to get your lvl 10 working on there.

[Boltaction]

OK full C02 tank. hooked it up and it shot twice and started leaking real bad down the barrel. I unhooked it and replaced the power tube tip o-ring. then i hooked it up and it instantly leaks out the front, i pull the trigger, it shoots once and stops leaking but doesent recharge. trigger is about half charged.

[BigTrucker]

Are you using the right powertube o-ring for the level 7?? The level 10 powertube o-ring is flat. Also make sure you didn't put the on/off pin back in up side down, that is if you are using the stock on/off.

yes it is the right o-ring. id be happy with a level 7 mag right now. ive replaced every o-ring in the power tube and it somehow still leaks down the barrel when the velocity is turned up enough to pressurize the gun. it will shoot once and the trigger goes limp and it stops leaking. when i take the valve out, the bolt never seems to come with it (wierd) and the on/off assembley is coming out wierd. the main stainless piece comes out by itself (without the on/off pin) then the brass, then i need needlenose to get the pin out.

I've tried everything i can think of and everything anyones told me to try and its just so frustrating cause the whole time im just thinking "WTF! its a friggin mag, its not supposed to be this difficult!" know what i mean?

[Boltaction]

Somthing has to be blocking somthing, somewhere. Tomarrow im taking every fitting off this gun and probably just bypass the vert adaptor. I got some extra steel braided stuff layin around so ill just go straight from the valve to the ASA.

BTW does anyone know the exact size of the screws to hold the ASA or drop to the grip frame on the mags? I have the benchmark in the video and a double trigger (i think its a benchmark) but they should be all the same right?

thanks,

SW

It sounds like your new problem is bolt stick. What size of powertube spacer are you using? You mentioned replacing the powertube tip oring. Don't worry about it. It only holds the tip from turning while the gun is shooting. The only oring in the level 7 powertube that matters is the one behind the powertube spacer. Make sure you are using the level 7 bolt spring and not one of the stiffer level 10 springs (although they should work with a higher velocity setting). Turn up the velocity setting.
