Fortunately there is a wealth of information online, especially on the ar15.com forums.
On the other hand, I don’t imagine that I’ll finish this project for another few months, since I have barely begun to gather the pieces. I certainly won’t have it done before the Appleseed shoot in mid-April. I guess I’ll have to wait for the next one. That does give me a bit of time to make up my mind on the specifics of my build; after all, this is a big step. If I choose poorly, I could end up using my fancy smoke pole to bash in zombie heads instead of shooting them from a safe distance away.
My brother asked me the other day why I needed a gun. I didn’t have a snappy-yet-relevant comeback for him at the time, but I suppose I’m just doing my part to lower the crime rate.
