A Moving Vehicle Field Experiment to Determine the Effectiveness of Circular Bracketing Sights on the M16A1 Rifle
A field experiment was conducted to determine whether a circular bracketing sight, framing the front sight on a standard rifle, could enhance the effectiveness of the rifle system in short range, stationary target engagements from a moving vehicle (5-10 mph). Two bracket sights (1.32 and 2.64 inches in diameter) were mounted on M16A1 rifles. 'Type E' personnel targets, at ranges of 25 and 50 yards, were exposed individually in random sequence for 4.5 seconds. Ten enlisted subjects each fired 20 (3-round) bursts at the targets using each bracket sight and an unmodified control sight. Results showed that there was no significant difference between sights nor were there any significant interactions. Hit probability per burst was low (20.3%) due to vehicle bounce. (Author).
