Hello to all. I'm a retired Marine Gunny living in the Socialist Republik of Illinois. Been interested in the 6.8mm SPC since I read about it when it was developed. Decided to get a AR lower and put one together in this caliber before Our fine Governor, Comrade Mayor Daley and Comrade Sen Durbin have their way this year. They've been trying to ram threw legislation to ban ALL semi-autos and anything that holds more than 10 rounds. Guess 5 rounds will be next.
