Called the LE901-16S, Colt's 7.62x51 mm NATO is an "out-of-the-box" concept that's a marriage of the AR-10 and AR-15 platforms. An adaptive rifle that uses a highly modified and upgraded AR-15 lower receiver with an equally unique AR-10 magazine well, the LE901-16S quickly converts to an M4-type carbine in 5.56x45 mm NATO. Conversions for the AR platform aren't a new innovation, but Colt's LE901-16S is a unique adaptation.
