Why cant you pick up that AR at the start of keyes?

dunno for sure but i would speculate that it is empty... In the MAW right after you fight the 5 or so sentinels in the bridge when your walking back through the armoury type area there are tons of AR's and Shottys on the ground but you can't get any mmo out of em cuz its all depleted... if you didn't have an AR then you could swap your current waepon for it but you would have no ammo...
I think that AR in Keyes is a glitch. I've never been able to pick it up, either. And sometimes it isn't there.
its only there if you skip the cutsence
