Hello, could someone help me identify this cool pump?

Bought this at a swap meet but I don't know what it is. I need to clean it up and test it sometime next week.

MAC-1 Annihilator. Very cool. Avengers were built from PMI-1 bodies.

Yep, this is built on an E series (.20 Cal). I really like, that it has not been side-tapped.

Awesome and Thanks for your help, paid $30 for it this morning from a Grandma who used to play woods ball.

You flat out robbed that woman!

Didn't mean too, not sure what I will do with it. Maybe clean it up and take it out for a day, then maybe sell it??

She is a cool grandma to have played woodball with this gun!
Nice setup, worth more than $30 hope you did not negociate at that price
Would pay more than $30 just for the stock with tank holder

If I sell it I will keep it the way it is, don't want to part it out.
