While many weapons experts consider slugthrowers to be
completely out of date, and there are still a few manufacturers
that still produce high quality anti-personnel firearms. TRK Ltd.,
a very high end manufacturer, saw an niche to be filled, and began
work on their S line. The S-90 was the first of those weapons to
be offered for sale. Designed to fire rounds of just about any
caliber (by fluid modulated contraction or expansion of the barrel,
and other mechanical innovations), and any type, the S-90's barrel
contains superconductor rings of alternating polarity that add
electromagnetic thrust to the shells own propulsion mechanisms
(usually chemical). As with all TRK weapons, the S-90 meets very
high exposure and durability standards. It comes equipped with a
gel cushioned shoulder stock, single action and chain loading
options, a fold out bipod, and a telescopic sight.
