Hello!



I have a severe problem with JJ-Airsoft L96 trigger on Well MB01 I´m building.

All works fine with stock trigger but with JJ trigger the piston won´t lock. Yeah I know, dont buy cheap stuff but the customer wanted it...


The pistonsear seems to be about 1,5mm further back than on the stock trigger but I don´t believe this causes it. I´ve tried lowering it via AEG shims, but after 2mm of shims I give up. The piston makes contact with the sear as it has made visible marks on the front of the sear. Any ideas? Today I´ll try with another spring but I don´t believe it is the reason as the trigger works if I pull the rear of the trigger lower.


:shrug:

I had the same problem. It was down to spring binding because of the extra 1.5mm move back. I also had to grind off a small flat on the top of the sear.

Ok, so I´m at the right track. I´ll try that different spring first and then shave from the top of the sear. Did you shim the triggerbox lower?

Didn't need to, grinding the flat on the sear did the trick.

Thanks for this info. I am eyeing this trigger for use with the stock piston. Too bad these aftermarket manufacturers can't get something as simple as the correct dimensions right. Take a stock Well trigger and copy the location of sear and spring stopper. Why is that so difficult for them?

On a side note, I suppose you'll get a little more air volume when the piston is moved more rearward as long as the O ring doesn't move past the slot in the bottom of the cylinder.

So a shorter spring seems to be the fix. You may have to trim the metal rod that passes through the spring guide if that is still installed in your build which might be hitting the back of the piston head.

Well, shaving the top of the sear did the trick. About 1mm too long and because of that the piston did not catch. :doh:


Now working like charm. Funny how hard it is for the manufacturer to make correct dimensions...
