"David" Light Gauss Rifle
From BattleTechWiki
The "David" Light Gauss Rifle is an infantry-class adaptation of the Free Worlds League's light gauss technology. It possesses considerable range and stopping power, much less than the vehicle versions but still enough to threaten such units. A conventional infantryman can wield the weapon, but it is exceedingly heavy and requires a harness to properly handle it's bulk. A power backpack is also often included to meet the gun's high energy demand, further increasing the burden on the gunner. Battle armor such as the Longinus can also make use of the "David", but the weapon requires additional modification and cooling systems to fit it onto the armor.
