Hatsan 95 vortex qe cocking force

Sorry for the late reply, Paul. I discovered that I don't have the correct punches to take the gun down. I did get the stock off and I see some rust around the nylon bushing, but most everything else looks to be lubed well. I will get some punches and take it down further as soon as I can. I don't have the spring in mine, I have the gas piston.

Ken,

I'm not having an issue with the spring piston portion of the gun, my issue is the spring loaded locking lug, for lack of the technical term.  Yesterday I eplaced the spring with a lighter, shorter spring.  That still did not seem to work.  I have polished both sides of the wedge that holds the barrel closes, as well as the pin it locks against.  I have also applied a silicone grease to all metal surfaces.  The lug moves freely enough, but it is still impossible to open without actually laying across my lap and hitting the barrel with my fist.  Which hurts, BTW...  I feel the lug sticks out to far and that's causing it to not move out of the way of the pin when adequate pressure is applied to the top of the barrel.  It's also difficult to close, but that has gotten a bit better.  Asked on the design of the lug, I'm at a loss as to how I can keep it from sticking out too far and still keep enough spring tension on it to retain the pin that holds it in place.

Also, if you compress the lug with a c-clamp enough to take pressure off the pin, it will probably fall out with a little encouragement from an end of a paper clip.  Thus my concern for not just shortening the spring enough to reduce the amount of the lug that sticks out.  Without some tension on the lug, I'm afraid the retaining pin will fall out.

Maybe your gas spring has too much pressure? Hatsan airguns straight from factory are very often overpowered and some people benefit from detuning. That gas spring has a option for pumping and releasing pressure maybe its worth to lower the pressure to see how it behave and find balance between reasonable cocking effort and energy produced.
