Avanti 747 not discharging all air

[targetceasefire]

I noticed one of my Daisy Avanti 747 club guns does not discharge all air when the trigger is pulled, with velocity noticeably less. I have insured the pump handle is within tolerances as per the manual and everything is properly lubricated. Does anyone know of any easy adjustment, or is it best to send to Daisy?

Maybe the seal(s) need to be replaced, there is gunk in the exhaust valve, the valve or hammer spring is weak. The only way to find out is to disassemble the pistol and see for yourself. Here is a link for the disassembly and reseal:

Thank you. I am sorry it has taken me so long to get back on here. I have been very satisfied with the accuracy of our 747's, and the responsiveness of Daisy's customer service, but have been disappointed with the build quality of our pistols. The valves have had to be replaced on all 4 pistols, and one needed a reseal too. I have completely torn down and cleaned them along with changing the valves, and they are all working now...
