Short stroking and chuffing. What/how?

[WetPaint]

As a prospective Mag owner, I keep seeing references to these fault conditions, and have been searching for clearer definitions of them.
As best as I can tell, "Chuff" is a partial firing, which leaves a ball partway down the barrel. The only way I can think of this happening though is low pressure in the chamber at time of sear release. Is this the case? If so, how does the pressure end up being low in the first place.

Short stroking? Not pulling the trigger far enough? or not releasing it fully?
What happens inside when it's done? On-off not clsing fully? Not opening long enough to recharge? Not allowing the sear to catch the bolt?
I just can't see how mishandling the trigger could cause a partial gas discharge in a properly-adjusted marker.
Anyone care to provide a correct explanation of these terms, or point to an existing thread that does please?

Welcom to AO first of all

definitions are close enough

if the lvlX isnt setup properly it can cause chuffing

if u short stroke it or doen allow the valve to fully recharge then it wil also/may also chuff usualy chuffing happens less and less as teh valve is worn in and you learn the feel of the trigger, shortstroking/chuffing is also more likely to happen with the ult and lvlX

Just got to say I did not relize you can shrot stroke a mag. I had one for about 8 mounths and did not relize this could happen.

"Chuff" is the sound made when a mag fires before the bolt is all the way forward or if the bolt returns too soon. Both are symptoms of too low of an operating pressure in the front chamber at the time of the operation.

Recharging the front chamber after a shot depends on the flow rate of gas through the on/off assembly. If you don't release the trigger far enough and/or pull it again too quickly, you limit that flow rate and shut it off too soon. If the front chamber doesn't have enough pressure to properly push the bolt and ball forward, the mag will "chuff". This is a "short stroke".

If you pull the trigger and fully release it before the next pull, you will never experience a chuff (malfunctions don't count). The mag charges faster than the time taken for a human to fully release and pull the next pull.

As mentioned before, as the mag gets broken in, it will chuff less and less. This is because the broken in o-rings allow the parts to move more freely so there are no limiting factors on the rate of recharge caused by the regulator or on/off.

Thank you.. This means a mod I had in mind might help. The idea is to disconnect the trigger from the sear as soon as the bolt starts forward. The bolt's rim will hold the sear down through the firing cycle, and recharge begins as soon as the sear hooks up again.
Recharge would be complete even before the shooter eases off trigger pressure. The only trigger action required is to pull it far enough to release the sear. Actually, if it was pulled too soon after firing, nothing would happen, since the trigger-sear link would not be re-established yet.
I have some ideas on how to accomplish this, but I'll have to get a Mag in hand to see if it'll work.

Actually, I don't think it's worth it. Shortstroking is not a big deal on a mag. Once youve shot it a couple of games, you practically never shortstroke, and the few times that you shortstroke, very seldom anything bad happens. You might shoot two balls, but then it's ready to fire again.

wetpaint- i second joni's opinion about your mod being a non factor.... and althought i do not know the design of your mod fully, i would have to think that it is mechnical in nature, you probably dont have anything pneumatic planned, this in mind, you'd be taking away what makes a mech mag so damn sexy.... that trigger pull. you would nto be able to have a reactive trigger, or one that offered any return force for that matter , if you were to make a system like the one that you described it would be a finite system of mechanical positions....not an infinite pneumatic response, thus you would lose the trigger feel.... without too many words.... just learn your mag's trigger, that muscle memory is hard to lose once you get it right...
