reload duration 3:14 - 3:38, jammed, unjamming from 3:40 - 4:06
LOL typicall murricans , im shootin , what de fuck ... that afghan boy got more nutz than these guys lel they dont even know where the enym is even get out of roundz hahahaha and then that shooting god dam he was lucky that he didnt received a shot . also lol at their shooting technique over the wall , they probably played too much playstation while they werent in a firefight hahaha , i could understand that if they wud shoot around a corner but they pointing the guns into the air most the time , just lel ... but nuthing suprises me
thinking that nato 5.56 is the shit is hilarious in itself , its some deadly close range weapon in real life but some 7.62 calibre wud have been better to blast that guys out of the area in the first video ... but well trend is going to smaller calibres anyway ... and the weapon industry should be happy sseing all dat ammowasting kek , from what i see its very easy to reload that gun , i bet some special trained soldier can reload that thing in some sec without packing the used mag back into the ammobag lel
it seems very easy , just put out old mag get a new one out adjust the first case with the belt and cock ...
