The Springfield Armory Saint Edge is a competition or tactical shooter straight out of the box. Premier components for quick-handling, improved accuracy, and performance comparable to custom AR builds costing much more.  At just over 6 lbs. the Edge is one of the lightest AR-15s on the market, featuring a patent-pending free float handguard and billet receiver with lightening cuts for effortless operation.  An SA proprietary muzzle brake virtually eliminates recoil, while the Melonite-treated trigger allows for a crisp trigger press with no creep. The Accu-Tite tension system ensures a tight fit with no rattle between the upper and lower receivers, paired with a premium M16 BCG that has been shot peened and MPI tested for reliability.  Adjustable pinned gas block, 1:8 twist, flared mag well, metal flip-up sights and Bravo Company furniture.
