Only 1 left

Availability: In stock




The Prometheus MC consists of the Dolos take-down system as well as our MC 6.5 inch MLOK handguard. Installing this kit on an existing AR15 or new build will allow you to drastically decrease the footprint of your AR rifle or pistol for efficient storage or discreet transport, with a repeatable zero each time it is assembled. Once mounted on the lock collar, the handguard will be a total length of 7 inches from the face of the upper receiver.


The kit includes:

  • Pantheon Arms Dolos Standard Lock Collar
  • Pantheon Arms Dolos Tri-Lug Assembly
  • Pantheon Arms MC 6.5 inch handguard


Dolos Lock collar:

The Dolos Lock collar provides the ability to add additional barrels to your Dolos equipped AR15. This unit is compatible with most Anderson Manufacturing, Rock River Arms, and YHM (and may work with handguards from other manufacturors, as well as Pantheon Arms handguards). Threaded 1.850"-30TPI.


Dolos Tri-lug assembly:

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

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.  


MC Handguard: 

This Pantheon Arms designed MLOK handguard for the AR15 provides tremendous value for your money. It is 6.5 inches long, MLOK on 7 sides, with a full length Picatinny Rail was designed especially for the Dolos takedown system. When mounted on a Dolos lock collar, the handguard will extend 7 inches from the face of your upper receiver.  The inner diameter is 1.750".

The differentiator between our handguard and those made by others is that we combine the strength of lockup provided by a threaded barrel nut with the clamping power of a compression lock. There are no jamb nuts or set screws to loosen, even under the extreme torque applied to the handguard when attaching your barrel to your rifle.
