Availability: In stock




The Prometheus SC consists of the Dolos take-down system as well as our SC, carbine length 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.


The kit includes:

  • Pantheon Arms Dolos Standard Lock Collar
  • Pantheon Arms Dolos Tri-Lug Assembly
  • Pantheon Arms SC 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.  


SC Handguard: 

This Pantheon Arms designed SC handguard for the AR15 provides a smooth 6.5", vented handguard for snag-free deployment of your Dolos equipped rifle or pistol. 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".

Note: The holes machined into this handguard are purely for air flow to slow heating from sustained fire, not attaching accessories.
