We manufacture all our parts in Oklahoma. I will be getting a list together this weekend and will post next week what we can offer that will include, uppers, handguards, gas blocks, several different flash hiders/ brakes, and barrels that we have available. What caliber barrels are people wanting? We build the fewest 223/5.56 barrel FYI. The 223/5.56 barrel market does not allow that to be viable for us except for specialty barrels. We have some super lite 7 1/2" and 16" 5.56 barrels available for sure, but not many. If anyone is interested in a particular caliber barrel, send me a PM. I will be able to post some pricing next week as well. I have had some questions about a web site and I am sorry to say we do not have one. We are the manufacture, we let the retailers build web sites. That is also why I can not offer everything we manufacture, we have agreements with the companies we build for. I really like the built in Oklahoma gun idea and wanting to let people know that more parts are being built in Oklahoma than you may realize. I am adding a picture to show a little bit of the process on a billet upper transformation.
