CA249 Trigger assembly

[Spa]

MY friend wanted mte to do research on MOSFETS and how they increase ROF, but after reading a review it looks like the application of a MOSFET increases ROF by 10%. (source: http://www.airsoftmechanics.com/home...iew/23/30/1/0/ )

So what i am wondering is if the trigger assembly switch in a CA249 is just a metal switch or does it have some special parts in it that somehow act as a MOSFET. And would a 249 be applicable for the MOSFET modification such as styandard v2's/V3's

The CA M249 trigger switching design is one of the worse desgined out there. Pull the trigger, the set screw rises and presses on the metal lever, which the end of it is dangerously close to the spinning sector gear. Truly fucking retarded design. Unless it's bent and shaped right, it'll get caught in the gear easy. Active Electronics sells the 'almost' exact same switch but it's under rated and welds the contacts together first burst. I've used the switch levers to rebuild the CA provided one and has worked.

As far as putting a MOSFET in, I'm not sure exactly how it'd go with that design, but I can't see it being much of a problem, but a better and more reliable triggering system is required in that gun, so a MOSFET would be a good start to doing so.

To get an increased rate of fire over the 10% the MOSFET provides, upgrade all plugs to Deans connectors, they have a lower resistance than the Tamiya connectors, so your 10% increase might go to 15-20%.

So modding a M249 with a MOSFET is out of the question since you cant really open a trigger assembly unless theres another way around it.

It's a completely different trigger system than any other gun. The trigger doesn't push a "conductive block" in between two contacts (one goes to the battery +, the other goes to the motor +) as most AEGs use, you'd literally have to mount one contact on the trigger and the other on the mechbox to get it to work similarly to other AEGs.

Basically, a complete redesign of the electrical system.

sounds like more trouble then its worth. thanks for the tips stalker.

No problem, I've been frustrated with Apoc's CA M249 the past while and it's constantly fatiguing trigger switch and metal arm, and seriously don't wish it upon anyone to deal with. Last time I dealt with it, the plastic housing of the switch had the plastic around where the metal arm's tabs sit degrade and open up, so the arm falls out. I'd have to use another switch body, move the internal contacts over to it just to make it work again. Like I said, worst design ever for a way to trigger an AEG.

Is there a difference between the stock CA249 swtich and the "Advanved Trigger Assembly" switch that CA sells seperatly other then the black and red colour?

Never heard of the "Advanced Trigger Assembly". Do you have a link?

3rd one down: http://www.classicarmy.com/search.js...49&pg=2&rpp=10

but its black..and not red (I have seen red ones in the packaging labeled as the advanced ones, never black)

but on the next page for a brand new gearbox they had the red ones:

http://www.classicarmy.com/search.js...49&pg=3&rpp=10

I checked the numebrs on both of the switches for the black andthe red "advanced" one and they are the same but a different color. Is CA just calling it advanced because its just a little box and not some big mess of contacts and small parts like a M14?

The advanced trigger assembly switch is almost a required upgrade for the 249. it was one of the first things i put into mine.

That issue you guys were talkin bout, with the bent metal lever and hitting the gears.. this solves that issue perfectly. the metal lever becomes MUCH more sturdy and wont bend as easily. its a higher quality design and its very apparent, even to someone who would have next to 0 experience with fixing these things.

So zekk, its the same trigger with the information written on it, but stronger internals for the switch?

I recall we had this chat a long time ago, but just i wann know why its that more advanced:P

[Zekk05]

come over sometiem this week and you can disect my 249. i guarantee youll see shit in there youd never imagined youd see in a 249 :P

Trip and I pulled out enough fur to coat a small squirrel after KS2.5

[jerryliang2k]

my gears ate the metal arm recently. Where would I be able to get one of these advanced trigger switches? The major retailers don't seem to carry them outside of a gearbox package.

WGC does carry one for the STAR M249. But that one isn't compatible with CA right?

thanks
