Daisy I was gifted 2 air pistols, a Beeman 800 and a Daisy 717. I need some help please.

Hello, this is my first post so i hope it's ok to ask some questions.

A very dear friend gifted me 2 air pistols to keep me busy and active during my cancer therapy. It's hard to do a lot of stuff we usually do together.

I dry fired the Daisy 717 a few times and it sounded fine... so i then tested it with a few projectiles.

The 717 shot very weak....and i could hear a little bit of rattling which didn't sound right.

I reviewed a video to learn how to disassemble the pistol but its very dark, tough to see fine details.

What i could find is that the wide bushing had disintegrated, almost to dust.

More worrisome is a little piece of plastic that looks like it broke off the rear sight....there is a tab that makes a right angle heading back up the rear sight base.

I guess i need new rings/bushings and a rear sight...are these available?

Also, where is there someplace to download a manual for the pistol. I found one for the 717 but it doesn't show assembly/disasemby and i can't find any for the Beeman 800.

Appreciate any leads and information as to how best to care for them and anything else i should purchase. I would very much like to use them.

thank you.

i had the same thing happen one pump and several firing why i have no idea
the only change was using a 006 valve stem Oring where a 005 is the right size and when the 005 Oring came in it stopped that problem also the problem only happen after the pistol had been charge and set aside for a leak down test like over night
when the trigger is pulled the cocking link pulls the valve open and holds it open

easy to work on until they are not
