This particular nasty weapon system is built for the borgs who hunt borgs (the canned meat canners if you prefer). It uses a not quite standard ammo hopper as part of the weapon system. The ammohopper holds 2 reloads for a HLAW (note HLAW) which is fired from a retractable over-the-shoulder HLAW mount (which holds a third HLAW round).
There is no way on earth (or in orbit) that anyone who isn't Military, Corporate-Military, or C-SWAT will be able to get one of these legally (and impossible illegaly). In fact many of those who have seen it in action suggest it be only used in military actions (which makes it perfect for use in Shockwave, or so I'm told) and the worst combat zones. But it's nothing if not deadly accurate (WA +2, smartlinked).
