How to make your 98c FULL AUTO

[Villhime98c]

This mod is pretty sweet and it worked for my gun. Its also very cheap. First open up your gun
-Push the sear forward just as if the rear bolt was pressing down in it.
-You should see a little space to the left of the black sear pivot pin.
- I took a shish-kabob stick (or a big toothpick) and grinded it down so it would stick in that little space. You can probably use a variety of other materials too, thats just what I used. Make sure the object that you fill the gap with is flush and snug with the sear or else you won't be able to fit the two frames of your gun back together.

It should go full auto when you press down the trigger and stop when you release it.

I think it fires around 13-14 shots per second, but thats just an estimate.

wow I just tried it and it works
The only problem is it cycles at about 1500rpm and the blowback blows the paint out of the elbow, I was only able to do single shots with it since the bolt moved so fast that no ball could get chambered.
its pretty neat though :)

[Villhime98c]

I had the same problem with the cycle rate so high balls could not be chambered. I took one of those mini orek XL vaccums and put it one the setting where instead of sucking air in it blows it back out. I aslo made a little feed tube out of a toliet paper roll so it would fit snugly in the detachable elbow. It only holds like 10 rounds. Anyways, I took the vaccum end and put it on the top of the feed tube so the air from the vaccum would force the balls into the bolt chamber. It looked like a generic warp feed almost. I test fired it in my backyard to my surprise my "vaccum feed" kept up with the high rate of fire on my 98c. Of couse it was all over in less than a second because I only had 10 rounds. ( you could probably stuff a whole bunch of balls in the hose that connects to the vaccum) You could never really play with it because you would have to haul around a vaccum and have a power supply. Its really cool just to fool around in your backard with.

nice experimenting!

[Villhime98c]

If anybody does this full-auto mod., I would like to hear your results.

[in trauma]

i tired that about a year ago!

it isnt worth the stress to the gun

it is impossible to feed ablls as fast as the gun cycles that way

i shot about 5 balls then chopped like crazy not a single ball mad it out hte barrel
and then they stoped feeding because it was cycling so fast that balls wouldnt drop

[S|\|!P0R|)]

You should be able to fix the cycle rate pretty easily. All you would need to do is make the bolt heavier. I don't really know how this would effect valve working, the bolt may move to slow and not open the valve far enough, but that's what they do on real guns. This would be so much cheaper than an electo!!!

[Scullyvan]

Hmm yes indeed
But how do we add weight to the bolt.. Or perhaps put something in that slows it down by creating friction I was thinking maybe a rubber coat or something like that but it would probably wear out the internals.
Or perhaps a warp-feed would fix the problem I’ve read they can feed up to 20bps

[S|\|!P0R|)]

If we slowed down the bolt to much the valve wouldn't open enough and we wouldn't get enough pressure... :| hm... It'd be cool if someone could manufacture an inner bolt out of tungstun or something to increase the weight. To bad none of the company's would ever do this, why make a $20 dollar solution when you can sell one for $300 and make everyone buy that. :pissed:

Mabey we could make it so it would only slow down on the way back somehow. :idea: Mabey an o-ring that has a flap on it that faces towards the back of the gun. It would still be really hard to get it down to like 600 rpm.

[Villhime98c]

Or you could get a really fast feeding system like the warp feed, but there around $150. Thats expensive (for me at least) My makeshift vaccum feed worked good, but you could not play with for obvious reasons. I'm gonna try to make a more compact version out of an old vaccum . Any ideas?

[S|\|!P0R|)]

I don't think you could really use it effectively that way. I bet your torturing your gun, and if you could even get a continuously loading system it would really waste paint and gas. There is no real use for 1500 rpm on a paintball field unless you get a bipod and stick in your bunker with a case full of paintballs sprayin the whole field.

[Villhime98c]

Yeah, I guess your right. There really is no point to fire at 1500 rpm. (Thats faster than most submachine guns) I'm gonna try to slow the cycle rate down. Maybe you could put pressure on the cocking handle to slow it down, maybe a spring or rubber band or somthing. I can't test that idea right now because I'm out of air.

[S|\|!P0R|)]

1500 rpm isn't just faster than most submachine guns, it's faster than any single barrel machine gun of any type ever made except for the German MG42. The average smg fires 500-800 rpm, and almost none fire faster than that. I know my guns :D

[Villhime98c]

I thought the German MG42 fired at 1200 rpm

[S|\|!P0R|)]

I'm pretty sure it was 1400 rpm, but Tom Clancey said 1200 in his books. They said 1400 on the history channel, but that's beside the point. You could probably slow down the bolt with a long rubber band. It would have to be long enough so it wouldn't pull the barrel back the whole length of the gun or you would have an adverse effect and very tense so that it won't just move with the bolt.

[want-a-bruise?]

yeah but how much is warp feed and were du i buy it? Or would power feed work? I hope power feed will work tell me if it will ok?:badboy:

dude power is just and angled tube that you attatch an elbow 2 it is supposed to help it feed be because it lets blow back gases out

powerfeed wont help

[NoNames]

I was reading this and I was thinking about it. You sear, first of all, gets the living hell pounded out of it. Second, you rear bolt, WILL, not maybe, WILL get rounded off. It happened with my RT and that used the blowback gases. What is happening here is you have and excessive amount of blowback inside of the gun. The valve seems to be cycling to fast for it's own good. Since I haven't checked WARPIG lately for any old Model 98's, I can't test this out. The other thing I am thinking about is that the valve could freeze up when cycling this fast. Another thing, if that little stick or whatever you put in falls out or breaks, the impact wouldn't be to good on the gun. I'd try it if i had an extra model 98, but not on my primary one. Also, if you weighted down the front bolt, you would have to re-design the gun. The front bolt is a certain weight for a reason. If it was heavier i wouldn't go forward quick enough, or not at the right time and it might chop a ball, or it would wear out the gun. Also, if it was too light, it would go forward too fast and might pinch a ball, and the same effects. This is just my opinion too. I'm hoping it's right. If you get it to work and i get another m98, i might try it out. Also, I'd get the warp feed at a shp, unless you know someone who can install them.

[Villhime98c]

That would suck if your rear bolt was rounded off. I'm aware of the stress this mod does to your gun, I'm experementing on different ways to relieve this stress by slowing down the cycle rate. So far nothin yet, I'll let you guys know if I find somthing that works.

[SpYdEr_RyDeR]

I tried it with a stinray (who cares about a stingray), it cycled so fats that when i fired it i couldnt let go of the trigger, its weird i thought i could just like hit the trigger a couple times to see if it would work, but every time it would just shoot the paint back through the feed, it was a ***** to clean.

But i thought of how funny it would be if it worked, be like, i'll play you with my stingray, i dont care if you have an autococker, and then light em up.

[Villhime98c]

lol, we did the same thing with my friends stingray. When we played we didn't even have to put paint in it to scare the crap out of the other team, we just dry fired it. It kept thier heads down really good.

[i like tictacs]

ahahhahhah, i am buying a stingray now!

[Squidboy]

I would have to do some serious experimentation with my friend's M98 to find out but, what would happen if you cut the kebab stick in half and sanded it so that it would give a tight fit on the top and bottom of the bolt, it would probably slow the bolt, If it is going too slow to open the valve you can just sand a minute bit off of the sticks. You could also cut the valve spring to lessen the ammount of force needed to open the valve fully.

[Villhime98c]

Hmmm, intresting, I'll have to try that. So your saying to place filed down halfs of the sticks above and below the rear bolt?

[Squidboy]

Yes, but I am not sure how it will work. Try and make the sticks as long as the bolt from the full-back position to the front of the bolt in the full-forward position, in other words make the stick so that it always makes full contact with the bolt through the whole cycle

[Keebler]

wouldnt the action of the bolt grind the sticks until they werent in contact nemore? i think ud need a stronger material, just my 14 yr old, lack of sleep, been inhaling jalepeno fumes all day cuz i left my nacho plate in my room idea tho.

[Squidboy]

I didn't say it would last very long, mybe a game or two if you were lucky.

[Villhime98c]

I'm responding to somthing Nonames said a while back. He said your sear would get the "living hell pounded out of it." Idon;t think thats true, I agree the gun does cycle ungodly fast and it causes pressure, but while the gun is firing in full auto, the sear is disengaged the whole time, thats the trick that makes it full auto in the first place.

The problem with this mod is that it cycles to damn fast for the balls to feed!! I put my 12 volt revvy on it and it could only fire the one that was chambered. There are two solutions, get/make somthing that will keep up with the insasne rate of fire, or slow down the cycle rate itself. Well I've tried to slow down the cycle rate by attaching rubber bands to the cocking handle to slow the rear bolt, that didn't work. Havn't tried squidboy's stick thingy, yet.

The only solution I can think of is to make somting that can keep up with the rate of fire. It needs to be somthing like the warp feed, that pushes and puts pressure on the balls to get into the chamber.

[Squidboy]

Anybody got a Warpfeed? Instead of attatching it to the gun like normal, just get some large diameter hose and use that to act as a tube extension. To test the warp feed idea though, you could just set the warp feed on a tabel and use it like that.
