Screw in pin for bolt catch?

[joemama]

I picked up an 80%er that was pretty cheap and it has a screw in pin for the bolt catch. Anyone know where I can get an lpk with that pin or somewhere that just sell that pin? I'm not sure on the brand of the lower since I just bought it off a guy at the range. Was to cheap to turn down but I'm not sure where I can get this part.

I'm a determined sorta guy & have a Quentin defense lower with the screw in bolt release. Trying to help here, I'd call them & ask if they sell the part?

Do you guys think that set screw will fit an ar-15 lower? I looked up Quentin defense and it does look like that might be the brand lower it is.
