Default Pellet gun will not pump

I have a Crossman 2100 Classic Pellet/BB Repeater gun that is only 10 months old and has been used maybe 5 times. When i went to use it the other day, there was no compression to pump it. I know it was never over pumped as i was always there when it was being used. I don't believe it has a cartridge, does it?

Drip some veggie oil down the pump assembly and work the pump in and out. Chances are that the pump cup got dry and won't hold compression.

The pump area looked lubricated already. I did try a couple drops of oil like you said, still no compression. I did find out one thing though, somehow, when i opened the chamber, there were three or four BB's that came out. I am not sure how this happened, but, could an overload of BB's like that cause the problem to lose the compression?

I don't know the specifics on your BB gun, but generally, when a pump like that fails to function, it's due to a dry cup.

Do you still have your owner's manual?

Awnser is NO.

The problem is, the compression cup is rotted and will no longer hold pressure.

The gun is less than a year old and has been stored indoors. Is it normal for the cup to dry out that fast?

How long was it sitting in the store before you bought it though?

I'd try calling Crossman's customer service and see what they say.
