Some topics addressed include: the history of the arms trade in Syria; countries of origin for weapons and ammunition listed for sale; type, sub-type, make, and model of those weapons; notable sales, including rare or uncommon weapons; average prices for models of SALW; and the prominence of blank-firing pistols. Also discussed is craft production and modification of weapons. The authors documented a wide range of locally made or modified firearms and accessories, from craft-produced suppressors to the modification of AK-pattern rifles into bullpup configuration.
