Hardened Arms is a growing company based in Washington State.  It makes sense that folks living and working in a land that sees limited sunshine would create a way to fight the dark and what lurks within it.  Boasting dual 1150-lumen illumination built into the hand guard the LumaShark is available both as a complete rifle in one of three calibers or separately as just a hand guard.

We recently spent some time with the complete rifle and found it to be a solid setup.  If you’re thinking what I was; YES, there is ample room inside the LumaShark for s suppressor.  Build specs for the completed rifle meet or exceed what most AR consumers are looking for these days.

Hardened Arms Forged Lower:

• Mil-Spec Dimensions
• Mil-Spec Lower Parts Kit Installed
• M4 Collaspible Stock Installed
• Works with all standard AR15 magazines

• A purpose-built rifle with integrated lamination seems destined to be a close-quarters-only type of rifle, but groupings at 100 yards show it’s a rifle ready for many roles.  As you can see from the shooting impressions video there is no doubt that the LumaShark accomplishes its mission as a stand-alone hand guard and as a complete rifle from Hardened Arms.
