"The FN stamp looks pretty clear to me. Looks more like something we left the Iraqi army that they dropped while running away."
Looks exactly like that, actually. My understanding was that we were not providing any M4/M16 type guns to rebel groups/etc. as support materiel in the middle east until quite recently (like, several months back, and in small numbers), so FNH-made M4s likely date to US ground-deployment in the region, or some covert gun-running operation (aka soon to be scandal). Entirely possible that some Cartel is selling guns over there; God knows they are buying up everything that throws lead in that part of the world. Not sure how it's a civilian problem, though; given the configuration of the weapon, it would have likely been sold/given to the Mexican federales as a DEA aid thing, with the full knowledge it would eventually 'seep' into the cartels infiltrating/controlling them (or simply be used to murder autodefensas.)
"Well my actual point is that if CNN has incorrectly labeled this as an AR-15 semi-automatic they need to be trounced for continuing the AR as an "assault weapon" lie. And I guess at that point this conversation goes to activism forum for a request for a mass mailing."
Yes; CNN conflating a select fire rifle our military stupidly left to the traitorous Iraqi Army unit that defected to ISIS, with semi-auto variants produced and sold domestically for law-abiding sport and self defense is something they should be trounced for. Many of these guns were subsequently taken off dead Daesh goons --shrapnel damage and all-- and jerry-rigged back into operating condition by Kurdish shade-tree gunsmiths working to fight our battles without military aid.
