I don't own one, nor have I seen this problem. But I would suggest to check the sear. Maybe it's got a problem resetting itself, or maybe there's something preventing it from resetting?

That's NOT a problem.  It's actually the same behavior on the REAL Vector because the firing mechanism is working like a CAM system.  Sometime when switching to 2 round burst the rotation has to turn by firing ONE round first then it will engaged.

I'm going to Pin this because I expect people to ask this question.  Please spread the info.

No no no..the gun cycles and fires 2 rounds..but when i release the trigger..it fires a third round..ill do a vid later...i understand that the cam maybe in the position that when switched from semi or full auto to 2rd..that it maybe in the position of half the 2rd cylce..and when the next shot is taken it will fire one round, completing that half cycle, then when next shot is taken, it fires a complete, 2rd cycle..what im refering to is completely different..ill post a video later if you dont get what im trying to explain.

The problem i am having is somewhat of a potential safety issue..that the gun fires when releasing the trigger..

So two round burst is actually becoming a three round burst (2+1)? This might sound trivial but have you actually counted / seen the quantity of BBs discharged to confirm the 2+1 behavior?  Due to it's high ROF I wouldn't be surprised if its actually 1+1, which would allow the burst mode to act like full auto.

Yes yes yes I understand that, what I am saying is have you actually counted the amount of BBs fired when using the 2 round burst from pulling AND releasing. Even though it seems like it might be firing 3, in fact might by 2; the trigger release fire would be the second BB. I know there is a firearm that has that mechanic with their burst mode, I just can't remember if it is the Kriss. The mechanic is actually a safety feature in the firearm because it prevents accidental discharges with a round still in the chamber and the mag out; think
of it as an auto clear. Additionally, the mechanic allows for a faster ROF than standard semi.

you can see the third shot being cycled after the two rounds and the triger released. that is odd? like to here what becomes of this and how it gets resolved.

Yes! You see what im talking about! Yea..i will try to figure out why the sear is not engaging long enough for the trigger sear to engage

I can see it too. It is indeed chambering a 3rd round and firing it after the release of the trigger! Don't know about you guys but that's a potentially big saftey issue there. I don't know what to tell you Boobie maybe try disassembling and reassembling the auto sear? Or even the whole trigger mechanism? You could have some fine dust or debree stuck in your trigger or sear causing it to slip another shot through. What mods have you done to it? something involving the trigger?

Worst case being you have a lemon because I haven't heard of this issue pop up anywhere and I know some guys that have skirmished with 2 round burst like 24/7 since December 20th and still runs smoothly.

Okay folks..after 2 nights of taking this damn kriss aparti found what the problem was. Part #27(trigger bar) was bent at the end where it engages the hammer. If i recall correctly i tried to pull the trigger with the hammer cocked back and the upper/lower was separated..because the full/2rd sear was engaged with the hammer, when i pulled the trigger it of course did not release the hammer and therefore bent the end of it as i pulled pretty firmly..so i heated the trigger bar with a torch and bent it back..the problem with it bent out of shape was there was too much clearance and the trigger bar would not engage hammer as part # 35 was disengaging. The timing was off with the bar bent. Now it works perfectly..so this thread should warn folks:
WHILE HAVING THE UPPER/LOWER APART, DO NOT ATTEMPT TO PULL THE TRIGGER,  UNLESS YOU HOLD DOWN FULL AUTO SEAR (part#27), THEN PULLING TRIGGER, TO RELEASE HAMMER!

Hey guys, need some help with the Kriss. After I shot a few mags, the gas started to run out, I charged the magazine again and when I switched to semi-auto, the gun would shoot all the rounds in the magazine. I have taken apart the gun and I am thinking that the problem has to do something with the primary sear (27) and/or selector cam (28). Can anyone help. Thanks

Hi shangeric, if you are shooting full auto, the magazine gets cold fast. If you are shooting in cold temps, the magazine will get cold fast as well... when the magazine gets cold, the gas gun loses performance and gas efficiency. How long are you charging the magazine for? Try charging it for longer to see if it helps with gas efficiency.
