The Dolos Tri-lug assembly with positive lock attaches to your upper receiver with a custom castle nut so it can be removed if you ever wish to move it to a new upper. It is included with all Dolos and Prometheus take-down kits. Installation hardware is included.
Note: Please do not remove any pre-installed screws or hardware from the tri-lug assembly, unless a Pantheon Arms employee is providing steps to do so, to avoid lost items and/or rendering your Dolos unusable until replacement parts can be acquired.
