M16A4 + ACOG to 500yds: Practical Accuracy (BCM upper)
This review tests the practical accuracy of an M16A4 build with a BCM upper and Trijicon ACOG at distances up to 500 yards. The 20-inch barrel proved advantageous over the M4 at longer ranges, aided by the ACOG's clarity and BDC reticle. The test utilized IMI 55gr M193 ammunition and demonstrated a high hit rate once hold-overs were mastered.
