A field experiment was conducted to determine the effectiveness of a circular bracketing sight in improving the hit capability of the M16A1 rifle at low-light levels at short range in quick- reaction situations. Eight riflemen fired at four pop-up targets that appeared for 2. 5 seconds at ranges of 20 and 40 meters. The subjects used weapons fitted with the standard sight (control) and a circular bracket sight. Testing was conducted on the Live Fire Instrumented Range at Fort Hunter-Liggett, Ca. , at a low-light level of 0.25 footcandles. Results showed that the bracket sight was 42% better than the standard sight over the entire experiment.
