The Tactical Carbine, Enhanced


The Eclipse features all of Cobalt’s technical advancements, with a familiar and utilitarian shape. The receivers are machined in-house from 7075 aluminum to maintain quality and fit. They are anodized in a type III hard coat before the entire gun gets a protective and cosmetic application of Cerakote. Fifteen-inch M-Lok handguard features a full-length Picatinny top rail.


Cobalt’s patented DUAL DROP adds new functionality to the AR-15 platform. The system allows the shooter to trip the bolt release with a thumb after a mag change while keeping the weapon on target. The magazine, selector controls, and charge handle are fully ambidextrous. The trigger is an enhanced single stage unit which offers light, crisp performance.

Operating System

A premium M-16 bolt group is treated with a lithium-iron surface conversion to deliver long-term reliable operation. The ECLIPSE is constructed with a fixed gas block to ensure full power gas delivery to the bolt group in adverse conditions. An H2 buffer improves reliability and recoil impulse.


4150 CMV steel is treated with a lithium-iron surface conversion to add strength, rigidity, and resistance to heat and erosion. The barrel’s contour has been carefully designed to increase inherent long term accuracy and overall balance. Standard chambering is 223 Wylde and features a 1-8″ twist 5-R rifling profile.


The “S” package replaces the 16″ standard barrel with a 14.5”, permanently attached to Cobalt’s linear device. This upgrade is effective at directing blast pressure away from the shooter and makes the rifle an effective striking weapon.
