Help needed on information on this rifle.

[LSUJon]

Hello, i joined to try to help my Marine Corps buddy whose father recently passed leaving him with a couple of air rifles. He is now looking to try to sell them and turned to me to help him with it as I’m pretty familiar with modern firearms. However, I am definitely out of my element when it comes to air rifles. From what I can gather, he has, what I believe to be a custom Gunwerks .50 cal air rifle. Any help with cost/ where we can find more information or best place to try to find a buyer would be greatly appreciated. I attached some photos of it. I’m waiting for him to find the order form it came with.

Thanks in advance.

I dont think thats an airgun. Looks like a muzzle loading powder gun to me

A Google search tells me they are very accurate and very expensive but thats all I got

Looked it up. MUZZLE LOADER, not airgun. We don't discuss those here per the rules.
