Michael Oxlong's Review of Proof Research PR15 6mm ARC Carbon Fiber Threaded Barrel

This is my 4th Proof Research carbon fiber barrel, and also my new favorite. Super super light, looks great, and is one of the main contributing reasons to my being able to build a .46moa AR-15. Combined with a Lancer carbon fiber handguard, the gun with a Vortex Razor gen II 4.5-27x56 and a fully loaded 15rd mag is less than 9lbs.
Pros:
  • Super Light
  • Sub-MOA capable
Cons:
  • None
Would Recommend: Yes
