The shoulder mounted machine gun is similar to the minigun, but with a slower rate of fire and the bulk of the weapon resting on the user's shoulder like the missile launcher. Due to its high damage per shot and good rate of fire, it is the most effective 10mm weapon in the game, if the player does not need the lower Strength requirement and silence of Gun Runners' Arsenal's Sleepytyme (or if the Gun Runners' Arsenaladd-on is not installed). However, it can be difficult to maintain, as only other SMMGs can repair it even with Jury Rigging, and it is extremely expensive to repair unless the player has a ready supply of weapon repair kits. Alternatively, if the first rank of ED-E's upgrades was found, repairing this gun will not be a problem.
The shoulder mounted machine gun can fire a total of about 3,995 standard rounds, the equivalent of 67 reloads, or 54 reloads when modified with the extended magazine, from full condition before breaking. When modified with the mechanical upgrade, it can fire a total of about 4,995 standard rounds, the equivalent of 84 reloads, or 67 reloads when modified with both the mechanical upgrade and the extended magazine.

The shoulder mounted machine gun is considered a unique class of weapon, and therefore cannot benefit from the Jury Rigging perk.
xbox360 Picking up one in lesser condition than the one in your inventory may replace the one you already had with the more damaged copy. An easy way to prevent losing the SMMG in better condition is to equip it before picking up the more damaged one. Keep it equipped until you give it to ED-E or use it for something else.[verified]
pc Installing the mod SMMG mechanical upgrade will reduce the actual durability of a SMMG in full conditiondown to 25%, a 50~ upto nearly 75%. (v140525). [verification overdue]
