Where to Buy

The Dolos Lock collar provides the ability to add additional barrels to your Dolos equipped AR15. This unit is compatible with handguards using a 47x1mm barrel nut thread pitch.

Note: This lock collar is not the standard thread pitch typically included with a Dolos/Prometheus. Imported rails found on eBay, at gun shows, and from other sales organizations who import or buy rails from importers, will likely fit this lock collar. We do not have a list of compatible handguards for this thread pitch.
