Sig’s New Toy- THE MINI REGULATOR
This video reviews a Sig Sauer MCX Cane Brake upper paired with a Regulator lower, chambered in 300 Blackout. The presenter conducts practical testing, including shooting at 60, 150, and 250 yards, and tests its effectiveness on watermelons with both subsonic and supersonic ammunition. The setup is noted for its non-traditional AR-15 buffer system.
