Thats true. If anyone has the HK pack, try firing the OICW with it's normal mags then try it with the ingame M16 mags.
Also why wouldn't you guys use OTWs SAW pack. It's got everythingin it, the Minimi version, the US M249 version, the PARA Version, Special Forces Version, and the M240 MG aswell. Most with scopes also attached.
But your SAW is slightly wrong, what you've done is crossed it the Minimi and M249. You've used the foregrip of the Minimi and the stock of the M249. The version which youv'e used is incorrect. The same incorrect version is in Ghost Recon.
