Got my Mag, nice but shootdown?

[michbich]

Clean the Regulator Piston and Spring Pack,Oil and Use HPA.Should get NO SHOOTDOWN,CO2(no matter the expansion area)will have shootdown on a mag(unless its 90* outside ),Borrow an airtank from a buddy just to see,

If i'm not mistaken, the reg piston must be greased...not just cleaned and oiled.

Only the spring pack uses grease, and that's just to prevent rust and corrosion. All other moving parts that hold air require oil.

Short stoking on a mag is done when you don't fully release the trigger following each shot before pulling the trigger for the next shot. The limited opening of the on-off pin combined with the shortened charge time for the front chamber means there is less air available for the shot which leads to a misfire. This is magnified with CO2 because the air passages may become restricted at higher rates of fire due to freezing.

what I noticed, is if I pull the trigger inconsistantly, or pull a little before I am ready to fire, it vents the valve and I get drop off..

It sounds like you need to remove a level 10 shim or 2. I am assuming you have a level 10 installed based on the vent comment. It also sounds like you may be getting a bit of bolt stick. Remove the shims and go to the next larger carrier size using the same white oring.

sorry no lvl 10.

My mag is normal correct? I never shot a mag so I guessed they all did this..

It doesn't bother me too much as I never shoot fast anyways.. Im a pump player..

Change the bolt spring. A weak bolt spring slows the cycle time of the bolt and causes bolt stick and reduces the front chamber charge time. This leads to short stroking as well.

If you are getting a bit of leaking when starting to pull the trigger, it is a sign that you need a shorter powertube spacer. A worn sear causes the bolt to be farther forward than normal. The shorter powertube spacer corrects this.
