Welcome to the Tactical Toolbox YouTube Channel. Today we're unboxing and testing the Blackout Defense Quantum Dual Taper Lock Version 2.0 aka Blackout Defense DTL 2.0, or Blackout Defense Quantum MK II DTL. It also has the new Blackout Defense ZERO Trigger which is one of the Best Drop-in Trigger Upgrades for the AR-15 that I've tested.
Could this be the best AR-15 Ever?
