A reader sent in these photos allegedly taken of a Syrian arms bazaar in the rebel controlled city of Deir ez-Zor. The photos show a 12 year old boy, with a 1911 pistol in a shoulder holster that is to big for him, manning a stall selling loose 7.62x39mm ammunition, gun cleaning supplies, a RPG launcher SA7 anti-air missile/launcher, a variety of machine guns and a Mosin bolt action rifle.
Another reader tipped us off to this video showing a rebel manufactured single shot 12.7x108mm anti-material rifle manufactured from a DShK heavy machine gun barrel (although an expert told me it could have been made out of a Chinese HMG barrel). The approach they took to making it is very similar to the DIY .50 BMG rifles made in the USA by gun enthusiasts also using surplus machine gun barrels.
Thanks to our readers who sent us these tips.
