Springfield Armory Echelon COA 9mm 4" Bbl Black Handgun w/ Aimpoint COA Optic, 2x10rd Mags EC9409BFCLC-COA

The Springfield Armory Echelon 4.0FC COA Low-Capacity brings enclosed-emitter precision and modular performance together in a factory configuration custom-built for capacity-restricted jurisdictions. This "crossover" hybrid configuration matches a fast-handling compact 4-inch slide assembly with the uncompromised recoil leverage and hand purchase of a full-size frame. Built entirely around the serialized, modular stainless steel Central Operating Group (COG) chassis, the defining hallmark of the EC9409BFCLC-COA setup is its Aimpoint® A-CUT factory slide profile. This specialized direct-mount interface allows the pre-installed Aimpoint® COA closed-emitter red dot sight to sit incredibly deep inside the slide without using intermediate adapter plates. By removing traditional mounting adapters, the system lowers the optical height-over-bore measurement, mitigates shear strain on the screws, and ensures absolute co-witnessing with the tactile iron sights. Shipping with two compliant 10-round steel magazines, it delivers hard-use environmental protection against water submersion, rain, and debris.
