AR parts are plentiful and cheap for now. It's been I think a year and half since we did this? Maybe 2 1/2? I dunno... So, if only a couple guys want to bring parts and have someone help guide them through putting them together, we can do that at my place in Bartlesville, or if there are a larger number who want to do things to their rifles, we can probably arrange somewhere in Tulsa, or I might even drive to OKC if there is enough interest. I've got tons of spare small parts in a box that were all mostly all donated from Fat Boy Tactical. If there's not a lot of interest, that's cool, no biggie. I just put a rifle together today for a friend to give to his dad out of mostly spare parts I had laying around and it put me in mind of the class/get together we did a couple of times. I hadn't built one in a while, probably a year or so. But it's fun tinkering. Post here in this thread if you're interested and what you'd like to have done to your rifle, or if it's a ground-up build.
