--  Button rifled and stress relieved barrel turned to perfect concentricity with the bore for superior accuracy

--  Rifles fitted with this barrel feel lighter than they are because there is less weight out at the muzzle end

--  This contour barrel is more rigid at the chamber end than M4 profile

--  Chamber end is heavier to accomodate and dissipate the heat of rapid fire more rapidly than conventional

--  Mid-length gas system is improved over military specifications and has softer action cycling and recoil
     characteristics

--  Mid-length gas system means the front sight sits closer to the muzzle end, giving a longer sight radius
     for better iron sighting

A Note on .223 Wylde Chambering:

The .223 Wylde chambering was designed to fill in the gap between .223 Remington chambers and 5.56mm NATO chambers.  It was found that NATO chambers were inherently less accurate than .223 Remington chamberings with the same ammunition.  In order to attempt to fix this, the Wylde was developed to try to gain back some accuracy without compromizing the pressure issues created by firing full power NATO (and some overpowered foreign made NATO ammunition) in a .223 Remington chamber.  The Wylde's main difference is that the bullet does not jump as far before it contacts the rifling as it does in the NATO chamber.  This alleviates the pressure issue while gaining back some accuracy.

.223 Wylde can safely and accurately shoot all NATO ammunition and all .223 Remington ammunition.
