Grinding the on/off pin ?'s

[om3n]

So I am going to try grinding down my on/off pin a bit to help me RT better... I already have a 1100 psi input into my gun, but it's still not RT'ing like I'd like it too.

My question is what side do I grind down? The longer thinner side, or the shorter fatter side?

Thanks guys

If you grind it you do so at your own risk.


Now that that is out of the way, you grind down the thin side. The fat side seals air, so to throw off the sealing surface would be a problem.


Remember that metal is easier to remove than add. Check often, cut half of what you measure, measure twice.

Some more questions


1. What is the danger of grinding it, other than ruining an $8 part?

2. Also, would I be better off pushing more air out of my air tank's regulator, to say, 1200 psi?

3. What I want is I want my mag to RT like my Tippmann 98. Will that ever happen? Right now I cannot RT my mag in combat while I can if I concentrate off the field, but I can RT my Tippmann whenever I want. The Tippmann is second nature to me... the mag is no where near as easy. So will I ever get my mag as easy to RT as my 98?

You can run the risk of premature bolt wear if you take too much off the pin.

Yes, you'd be better off just upping the pressure (search for Zak Vetter and you'll see what I mean).

You might get yours to RT like your Tippmann, but then again all mags are different and the LVL10 can adversely effect your marker's performance as far as speed goes.


For example, my RT Pro would easily sweetspot in the teens and would top 20bps if I concentrated, and this is off of a 850psi output Crossfire reg!

Now that I have a lvl10 bolt installed, I can barely get a 2 shot burst off of the RT effect.
Does it suck not having the firepower? Not really, but that isn't how I play.
Does it suck not being able to show off an RT's true potential? Yes, it totally sucks.
Am I willing to part with the lvl10 to have the speed again? Not in a million years!

I'd be cool to get it to RT again, and I'm willing to tune it as much as I can and up the pressure a lot to try. But if it never happens again I'll still be happy enough just to know that it once did.


Sometimes you just have to play the cards you are dealt.

Unless you have digital verniers I would not do this yourself. Go to the AGD Store and buy a quad o-ring and the emag pin (.712). For $12 plus shipping you will have your original as a backup if you want to change it back.

as long as you measure it it will not matter. I grind them down all the time to put in e/xmags (from .750 to .712)

But pick up one of these if you are going to do it yourself

It only takes me 30-40 strokes on a flat file to bring a .750 down to .721 and unless you measure every 10 strokes or so you will have no idea how long your pin is.

While you are there you might as well pick up a set of these for changing out regulators in tanks.

BTW, Are you anywhere near Muskegon, MI? I used to work for a Paper Company that had a Mill in Muskegon. I've been other there a few times doing ESX Server work, nice area.

edit: Never mind... SE not W... Muskegon is on the West side...

Thanks for all the replies guys. So what would I need the o-rings for? I'm probably gonna go this route... I think that there is too much risk with whole filing idea :/

So what is the purpose of the o-rings?


And no sorry, I'm not near Muskegon

Yeah I know what you mean- I have been playing alot with my mag purely on semi-auto and I've been doing excellently, but the last time I played I was pinned down by a couple of guys with automatic guns and man it would've been nice to have an automatic gun to combat them with. But I agree, I will never get rid of the lvl 10. The lack of chop is amazing

[om3n]

Yeah man!!!

Again if you guys could let me know why I need the quad o-rings that would be great

[Coralis]

Quad orings have two sealing surfaces instead of one so they do not have to sit as tight on the on/off pin to provide a seal thus making the on/off pin slide up and down easier which in theory make the gun a bit more reactive.

Hmm ok that's interesting. Where does this particular o-ring go? Is it the o-ring that goes directly on the on/off pin, or is the the o-ring that the o-ring that goes on top of the on/off pin fits into, if that makes sense

[Coralis]

it goes in the channel/hole that the on/off assembly slides into, it replaces the two orings that would normally be there

oh, it replaces both of the o-rings that go on top of the on/off assembly? Ok cool Thanks I'll let you guys know how this works!

No, it only replaces the small white top oring. If you have the two oring on-off top, then you still need two orings. The black quad oring fits inside the larger urethane oring.
