A gang name, short for Mara Salvatrucha 13.
Also known as the "Vulcan" Minigun. The m134 is somewhat of a portable version of the Gatling gun, hence the "Mini" prefix. It shoots around 50 rounds per second through a rotary barrel system. Comparable to a washing machine in that, while it takes a bit of build-up (about 1.5 seconds) once its going, it will clean up quickly (and argueably efficiantly.)
A beautiful, powerful rifle, based on the classic M1 .30-06 "Garand." In its standard form, it has wooden furnishings, peep hole sights, a 22" barrel, a .308 Winchester (7.62x51mm) bore, and 20-round magazines. It uses a gas-diversion system, with a rotating bolt, which has two locking lugs. While it featured a fully-automatic function, this was generally not used, due to the muzzle deviation produced by the recoil, which lent to user inaccuracies. In its semi-automatic fire mode, however, it is a very accurate weapon, even without an accurized barrel. Modern variants include the M21, M25, and M14 DMR (Designated Marksmans' Rifle), all of which are still in use by the United States' Army and Marine Corps. All of the above are strictly semi-automatic, outfitted with scopes, accurized barrels, match-grade sights, improved triggers, and generally include synthetic furnishings. Some even have picatinny and fore grip rails. There are also civilian versions, called the M1A, by the privately-owned Springfield Armory, which has no connections to the government-run firearms maker, which was shutdown in 1968, by the DoD.
The M145 MGO is a 4 power optic used by the US Military for the M240 family of weapons and the M249 SAW. Inside the optic are lines and numbers showing different ranges to shoot.
