This mod takes advantage of SMOD's robust customization capabilities to offer players realistic, tactical gameplay with real-world equipment and firearms in the style of games and mods like Rainbow 6, Operation Flashpoint, Red Orchestra, and Infiltration.
That looks more like a SR-25 SPR
looks like a M16 with a scope on it
its a ar 15 acuclly
AR-15 is the "CIVILIAN" version of the M16, it uses a smaller caliber
actually the civilian version uses the same round as the military version, and that is actually a SR-25 BTW
Thats the marksmen version of an m16. or also known as DMR. Of course I dont know who's his long range fire is covering if he's all by him self?
This is an SR-25, Razor is right.
