Hello fellow snipers.. I recently purchased a metal trigger box for my MK96... I was excited to say the least due to the fact the stock one was falling apart.. However, upon chrono check-ins yesterday before a scenario game, I realized the trigger had taken 125 fps away... Not to happy about it... So now what do I do next?? Is there any way to get the fps back I once had?? Or do i need to upgrade my spring?? Which I already have.. Is there a certain part in the trigger mechanism itself I need to replace and or adjust?? Any info or input will help.. Happy sniping

Sorry but if I understand correctly you have 125 fps difference because you changed the trigger??? ???

Thats impossible. Take the gun apart, clean, regrease and teflon tape it and you should be back to normal.

What did you buy for a trigger unit? Because if it came with a metal piston, and you has a plastic one, that cold explain your problem.

Yes I hate to say it but that seems impossible. I think I bought the same replacement trigger for my MK96 (was it $30?) and my FPS stayed exactly the same as it was.

Take it apart and put it back together again. Maybe you changed the spring and forgot about it?

Yes, the trigger box was around $30. I have an aluminum piston and an m170 spring. However I'm learning that it might possibly be the o-ring but I'm baffled by the fact such a small part could have a huge impact on performance. Mgunner, what part should I teflon tape? I have a PDI hopup and I've heard of guys taping their stock hopup units to decrease air leaks. Could my hop up be leaking possibly? I just bought it along with a repair kit for it. But like I said, most claim it to be the oring on the piston.

I took apart my bolt only to realize that my cylinder head has a groove cut out in from from one of the bolts on the hop up backing out. Would that be the cause of the loss of fps?? If so where can I find a replacement cylinder head for a utg mk 96??

You know the piece of the head that slides the bb into the hop up? On the MK96 it is made of bronze I believe. There was a screw backed out on my pdi hopup and everytime i pushed the bolt forward, it would rub on the screw thus leaving a groove carved into it. However, I filled it with epoxy and sanded it and it seems to have helped. Lesson learned: If you have a pdi hopup put some thread lock on the screws that adjust the arms. They tend to back out over time. Kind of aggrivating if you ask me. I feel like putting the stock one back in because it was a little more reliable. Not accuracy wise, but the fact I dont have to worry about it while Im in the field. -Happy Sniping
