BSA BSA lightning, magnum information

I acquired a BSA, lightning magnum, 177 pellet gun. Serial number AR32094. It needs to be rebuilt, but finding any information on this is near impossible. I need a seal kit and manual on how to take it apart and put it back together. Are there better parts than the stock parts? I tried contacting BSA but have had no luck. Any help would be great. Thank you so much and looking forward to shooting this finally.
 
Air rifle headquarters has what you need. Have fun with the scope rail. It will be your most challenging task. It takes 2 things to get it off and back on. Skill and patience. Lots of both! The rail and rubber “gasket” are not available. Don’t mess them up. BTW you will not remove the piston without taking the rail off.
Not sure anymore if the trigger has to come off or apart.
Nice powerful little guns but challenging to work on.
 
Hello I am new to this forum my first and only Air rifle is a Benjamin bulldog .357. I am a fairly new to airguns. I am trying to locate a store or a person selling an AEA Terminator 2 .357 air rifle semi auto. It seems like they are very hard to find . Any suggestions would be appreciated. Thanks
