    I've purchased multiple 16" 5.56 barrels from WLA. They were all great quality and shot Sub-MOA. I was skeptical about the new 16" 416R barrels, but purchased one to see if it was worth the money. The answer is YES! I'm consistently getting Sub-MOA groups at 100 yards with 75 grain match grade ammo. WHAT MORE CAN YOU ASK FOR? Great job WLA!
