The Echelon employs a newly developed magazine for rugged durability, hard use and reliable operation. Blacked out in an all new scratch and wear resistant coating, the magazine features a capacity of 17+1 in its flush fit configuration and 20+1 with the extended base pad installed. The Echelon\'s Trigger harnesses the advantages of the Central Operating Group to deliver superior performance. Entirely contained within the chassis, critical components are machined from tool steel and highly polished for a clean take up, defined wall, crisp break and short, positive reset. The result is a trigger that redefines expectations. The Echelon comes standard with the tactical rack U-notch rear sight and a tritium front sight with luminescent ring. The hammer forged Echelon barrel is manufactured for elite performance. Long regarded as the gold standard in barrel making the hammer forging process produces a stronger barrel with a smoother surface for ultimate accuracy and service life. The 4.0\" barrel is Melonite coated for corrosion and wear resistance
