LaRue introduces a large-frame evolution of the proven Match Grade Upper (MGU) platform delivering the same precision consistency and reliability our rifles are known for in a ready-to-run upper receiver configuration. Designed to drop directly onto LaRue-pattern lower receivers these uppers allow you to build a true precision rifle system without compromise. Add a quality optic feed it match-grade ammunition or your own handloads and sub-MOA performance at 100 yards is easily achievable.
