S.F. mentioned this from Milspecmonkey.com: Videos from the recent SHOT show, demonstrating the Lula magazine loaders [2], and MagPul’s fully ambidextrous gas piston-operated lightweight .223 with quick-change barrels [3].

Oh, and in related news, the U.S. Army won’t be replacing the M4–or even retrofitting with HK-416 uppers. [5]
