Bullboss hammer trouble

Seth0764 · May 31, 2018

Hi all, im hoping someone can help me get this fixed. I have a bullboss .22 tuned by bwalton. When i cock the gun the hammer does not stay cocked it springs forward and i have to pull the trigger and then i can try to cock it again. I've try adjusting the hammer spring and then it works for a few shots then it starts acting up again. Has anyone had this issue and how was it resolved? Thanks

I don't know about that gun in particular but sounds like the trigger sear isnt engaging. try adjusting the trigger if thats possible.

Not sure if it is the same but if I try to adjust my Gladius trigger to light, it does the same thing. Try backing off the trigger adjustments just a bit.

I agree with the trigger adjustment being out of whack.....

I agree on trigger adjustment,you can make them to light and simulate what your talking about.

Same thing with mine in .25. I had the #1 screw (trigger pull weight) too light, so I tightened it up a bit for a heavier trigger pull and it resolved the issue. With the previously light trigger that I personally adjusted I got about 100 rounds thru before it revealed itself to be too light, causing the hammer issue you mention, as well as firing all on its own with safety on!!!!

After adding some weight it seems to be ok.

i believe the owners manual has the direction of turn wrong - just do some dry fire testing to figure it out.

***The size wrench (Allen) for rear most trigger screw (#1) I think is a #3, which does not come with the gun

Well my bullboss is shooting once again. The trigger adjustment did the trick. Hatsan has the info backwards though from what screw to turn to which way to turn it. Unbelievable..... Thanks again guys

Maybe i should start a new topic. Well after a few hundred shots the problem came back and now no adjustment will help. Hatsan has left me out in the wind. I have called and emailed them all week with no reply what so ever.

I will no longer buy any Hatsan products. My last purchase was an Ataman.357 over the Hercules for this reason no support. but i need to fix the ones im stuck with. Can anyone help
