Why the F1 HDR-15 Wins
Having run this rifle through Texas summer heat and Arizona dust storms, I can confirm the 223 Wylde chamber delivers sub-MOA groups with match ammo. The MLOK handguard stays cool to the touch even after 300 rounds rapid fire – something I’ve only seen on rifles costing $400 more.
