This is something I've been thinking of doing for the last couple of weeks. Most everyone I know has extra parts laying around for their AR that they bought in the past and either didn't like it or found something better. What I'm wanting to do is a swap meet where people bring their extras stuff like stocks, vertical grips, grips and other stuff like that and swap parts if they find something they like. They can either swap or buy it. This is something I was wanting to do locally. Has anyone every heard or done anything like this in the past?
