BCM AR15 - 8600 Rounds NO OIL & NO CLEANING
This BCM AR-15 endured 8,600 rounds without any oil or cleaning, demonstrating remarkable reliability. The test highlighted increasing sluggishness due to carbon buildup and heat, culminating in a failure to fire when the bolt didn't fully close. Gas port erosion was noted as a factor contributing to increased gas flow over time.
