ABSTRACT:
A retro-fit gas system for controlling the firing rate of the Colt M16 automatic carbine that involves removing the original short gas tube that has a predermined length and which has a longitudinal axis extending from its front end to its rear end and replacing it with a novel twin gas tube assembly. The gas tube assembly has a first gas tube whose front portion passes through a longitudinally extending lower bore hole in a junction block. A second gas tube has its front end removably inserted in a longitudinally extending upper bore hole in the junction block. A vertically extending cross passage bore hole in the junction block connects with gas ports in the respective first and second gas tubes thereby providing an extended length of gas travel passage distance for reducing the cyclic rate of fire of the Colt M16 carbine.
