Noveske SPR Match Barrel and Headspaced Bolt AR-15 5.56x45mm NATO Medium Contour 1 in 7" Twist 18" Stainless Steel with Low Profile Gas Block
All Noveske match barrels have a medium contour, bead-blasted satin finish, M4 extended feed ramps, and are threaded at the muzzle for the addition of flash hiders, muzzle brakes and/or sound suppressors. This barrel is shipped with a pinned, low profile gas block, gas tube, barrel extension and a factory-headspaced bolt to guarantee proper fit and lockup. This SPR 18" barrel has an intermediate length gas system, which is 1.5" shorter than a rifle length gas system. The intermediate position is optimal for an 18" barrel since it maintains reliability while also keeping the gas port pressure lower than shorter systems for a smoother recoil impulse.
