The Colt LE901-16SE is a semi-automatic AR-10 pattern rifle built on Colt's proprietary upper receiver with a 16.1-inch cold-hammer-forged barrel and a distinctive lower receiver that accepts standard AR-15 lower parts while using a Colt-specific upper. The LE901 was designed for law enforcement agencies transitioning from .308 designated marksman rifle platforms to AR-style controls. Colt's manufacturing heritage and mil-spec controls make the LE901 a trusted law enforcement .308 platform.
