I purchased this used FX Royale .22 walnut LNIB on 6-29-16 from AOA. The trigger pull is too light to hunt with. I called AOA and they were of no help. Then I tried to put air in the tank and the connector blew off. I changed the connector, same results. The connector clicks and I cannot pull it off, but it will blow off. Now I looked at the clearance around the male on the gun and there is no play in the stock to shift the port. I have a good picture but I am 73 yrs. old and not a forum regular. Thanks for the help.
