  1. Compact and accurate, very effective. Simple to work, fire and maintain. Adds 3 lbs to your rifle. Grenadiers then had to then carry additional ammo for the rifle. At least 7 mags of 5.56mm They already carried rounds for the M79 so no major difference in weight. A M203 gunners vest had spaces for 36 rounds at about 1 to 1 1/2 pounds apiece.
