WE F226 takedown lever stuck
 

so a few months back my stock takedown lever sheered. I bought a TM compatible steel take down lever (guarder I believe) and installed it. today I was plinking and noticed the bb's were just rolling out, which meant the screws in the hop up unit were loose. so I try to rotate the lever and it doesnt spin. I tried pushing the lever out and it's stuck as well. Tried a punch and hammer and it's not budging.

anyone have problems like this before? am I going to have to buy a new gun?

edit: I got the pin out with brute force...using an 11lb sledge. anyone know where to buy an OE takedown lever?
