However, it was also found that at the ranges being considered for this weapon, the standard shotgun shells had too much power. This led to the development of a shorter round, 60 mm long (2.36 inch as opposed to 2.75) with both the desired power and size. The use of the MAG-7 with these cartridges yields an effective range of 45 yards (41.1 m), although they have a proven lethality to 90 yards (82 m). The MAG-7 also has a detachable, top-folding sheet metal stock.
