Mac 11 Edit Meaning

1.

Both MAC10 and MAC11 are compact and reliable guns, capable of delivering a good amount of firepower due to high rate of fire (1100 rpm for MAC11 and a striking 1600 rpm for MAC11 in .380). But the light weight and high rate of fire resulted in marginal accuracy and relatively short effective range, thus make the MACs the good choice for building sweeps and inside-the-vehicle operations

Israeli commandos used the MAC-11s in their Aircraft Hijack Resque missions, thank to its to great firepower and low probability of over-penetration ad ricochetes
