The Echelon Alpha 4.0C brings Springfield's Variable Interface System and Central Operating Group modularity to a compact, carry-ready package at an accessible price point. The 4" hammer forged steel barrel and billet machined slide-both Melonite finished-deliver durability and corrosion resistance in a recontoured profile with deep, aggressive serrations for positive manipulation under any conditions. U-Dot sights provide fast, intuitive alignment with a high-visibility white-dot front and tactical rack U-Notch rear, and the optics-ready slide accepts today's leading micro red dots via direct-mount VIS compatibility. The serialized Central Operating Group chassis anchors the platform and enables future configurability, while the captive recoil system simplifies maintenance. Ships with one flush-fitting 15-round stainless steel magazine. 4" hammer forged steel barrel with Melonite finish, 1:10 twist Billet machined slide with Melonite finish and deep aggressive serrations Variable Interface System for direct-mount optic compatibility Serialized Central Operating Group chassis White-dot front sight, Tactical Rack U-Dot rear Small grip module, black polymer frame Captive recoil system Includes (1) 15-round stainless steel magazine
