The AR2 mag pickups dont match the one in the weapon model so some mods out there correct it, the first one that comes to mind is this one [gamebanana.com] but I personally would love to see a standalone version of this one [gamebanana.com] without the weapon model, it resembles HL:Alyx pulse pickups and make more sense than the mags since we dont really change it in the AR2 reload, tho the ammo crate will be innacurate.

What AR2 magazine?

any chance you can also port the AR2 magazine?
