Guest Posted March 27, 2019 Posted March 27, 2019 Like I said, primary sear and/or hammer. You need to clean and lube your frames and bolt, not sure how the recoil buffer is returning to full height if the bolt isn’t returning properly, the two are inter-dependant.
Jayshhli Posted June 6, 2019 Posted June 6, 2019 I have the exact same problem. Has as anyone figured it out?

Jayshhli Posted June 6, 2019 Posted June 6, 2019 Hey guys... really need some help. My guns trigger, after a few shots in semi will stop working and I’ll have to spam the trigger for it to reset before I can shoot again. I can feel the trigger ‘click’ back then I can fire again. 2 round burst and full auto are totally fine. Anyone else have this issue? ive checked my trigger bar, Sears, cleaned and lubed... what else can it be? Issue is only in semi. Has anyone figured it out? I have the same issue!
Schultz Posted June 7, 2019 Author Posted June 7, 2019 Mine is not fixed yet. Next step for me is sanding the sear but did not had the time to do it yet.
Schultz Posted July 30, 2019 Author Posted July 30, 2019 So i did sand the sear. Problem is still there. What i noticed is that when it stops firing and i open here i must push the trigger bar to the top of the gun to reset the trigger. When resetting also the full-auto sear moved a bit. Any ideas on this @rocketdogbert?

Any ideas on this @rocketdogbert? Im not sure I understand, the trigger bar doesn’t really go up? The return spring on the bar pushes it back up to allow the hammer to reset, does it look correct inside, like this?
Schultz Posted August 9, 2019 Author Posted August 9, 2019 Sorry for mine late reply, was a couple days out of town. If it does not fire i have to push the trigger bar (red circle) to reset the trigger.

I’ve never had the issue, but it sounds like your trigger spring (the thin, U-shaped bar) is not returning, so it’s either bent or lost its springiness
Schultz Posted August 9, 2019 Author Posted August 9, 2019 Some time ago i disassembled it. Was also thinking of a bad return spring. But then again it is weird that a first few shots (or burst or full-auto) are fine. I will disassemble it again and make some photo’s. Can compare the spring with a spare one i have.
Schultz Posted August 10, 2019 Author Posted August 10, 2019 Return spring looks to be oke. The bottom one is the spare
Guest Posted August 10, 2019 Posted August 10, 2019 Work through it logically. If manually pushing the primary sear (trigger bar) up resets it, either:- Return spring isn’t working properly Primary Sear is sticking First, if you know the replacement spring is good, try that. If that doesn’t work, either the primary sear is sticking in its guide, or its sticking on the primary hammer
Schultz Posted August 21, 2019 Author Posted August 21, 2019 Replaced the spring but problem still occurs. Made a vid. of the problem. Here you can see that after i push the trigger bar it all resets. E6055E4D-33C2-4D5F-9961-1B5895AF244E.MOV
Guest Posted August 21, 2019 Posted August 21, 2019 Your semi sear looks really worn, but you have to hold the auto sear up or the hammer won’t reset properly without the full lower in place. You must let it go through a proper cycle or it won’t reset. You did sand the sear nub, not the sear face? Have you checked the condition of the sear cup springs? If they are damaged, the sears won’t reset. The three cup springs are two different lengths, are they in the right cups? Check the parts diagram to get them in the right place, off the top of my head (I think) , the fulll auto spring is shorter, but check it first. Have you checked the wear on the tip of the primary sear? (The trigger bar) Do you have a standard trigger installed? Is the recoil buffer standard, rod not bent, spring pushing sufficiently to raise the buffer fully? Bolt returning fully into the hop?
Schultz Posted August 23, 2019 Author Posted August 23, 2019 I think i was lacking some information on mine latest vid, sorry. I assembled the Vector and took some shots. When the trigger was not working i disassembled the Vector, started the vid, and then you see mee pushing the trigger bar. You see that when i push the trigger bar it resets properly. You did sand the sear nub, not the sear face? I sanded around the nub, not the nub itself. Have you checked the condition of the sear cup springs? If they are damaged, the sears won’t reset. The three cup springs are two different lengths, are they in the right cups? Check the parts diagram to get them in the right place, off the top of my head (I think) , the fulll auto spring is shorter, but check it first. Yes i did and the springs are in the right place. The full auto spring is indeed the short one. Have you checked the wear on the tip of the primary sear? (The trigger bar) Yes, look good enough Do you have a standard trigger installed?Yes, V1 Is the recoil buffer standard, rod not bent, spring pushing sufficiently to raise the buffer fully? Think so Bolt returning fully into the hop?Yes
Guest Posted August 23, 2019 Posted August 23, 2019 This is how the semi sear should look once you’ve done sanding, though maybe less removed, you have to go very carefully Part of the nub has been sanded/filed off
Schultz Posted September 4, 2019 Author Posted September 4, 2019 Didn’t work. Still think it has someting to do with the triggerbar.

Schultz Posted September 4, 2019 Author Posted September 4, 2019 A little bit. What would this accomplish, looks like it is not touching anything on that spot?
Guest Posted September 4, 2019 Posted September 4, 2019 5 minutes ago, Schultz said: A little bit. What would this accomplish, looks like it is not touching anything on that spot? Trust me, this is the fix for a worn semi or burst sear. @Dan1712 and I have done this on LOTS of KWA Vectors. Take the trigger group assembly out of the gun, manually cycle it, study it until you can see what the various parts do. If you think the bottom of the nub doesn’t do anything, you don’t understand how the trigger group works.
