  • Information
This Noveske Shooting Team (NST) Complete AR-15 Upper Assembly is designed to excel in Multi-Gun and 3-Gun Competition, with each component being selected specifically to enhance the rifle's performance, balance and reliability under demanding conditions. The NST upper comes equipped with one of Noveske's legendary stainless steel match barrels featuring their exclusive 5.56 Match Mod 0 chamber for outstanding accuracy with both 5.56x45mm NATO and 223 Remington ammunition. This barrel is turned down to a lightweight contour for faster handling, and comes with improved polygonal 1 in 7" twist rifling, M4 feed ramps and a non-glare, bead-blasted finish. The upper's mid length gas system and highly effective SJC Titan Compensator work together symbiotically to significantly reduce perceived recoil and muzzle rise, allowing for the rapid, accurate shooting style employed by today's top 3-Gun competitors. Additional features include a forged charging handle, a pinned low profile gas block and a shot peened, MP-tested bolt housed within a Mil-Spec bolt carrier.

This NST upper includes a 13.5" long Noveske NSR-13.5 handguard with the proprietary KeyMod rail system and, with an outside diameter of only 1.48" (without accessories attached), is one of the slimmest, lightest, customizable handguards available for the AR-15 platform. The NSR free floats the barrel for greater accuracy potential and provides a full length, continuous top rail for the addition of optics and/or accessories (additional add-on rail sections sold separately). KeyMod accessories are quick and easy to install along the handguard's length, and don't require that the NSR be removed from the upper in order to attach or detach them. All KeyMod system accessories use captured backing plates that are inserted into an unused key-slot hole and then tightened into place via an allen wrench, eliminating the tedious and frustrating procedure of fishing separate backer plates down the interior of a handguard and securing them with loose fasteners as required by most competing modular forearm designs.
