I would also invite those that have been not adopting ARMA 3 based on the future equipment to come and join us at SimHQ this weekend. We have a lot of addons, which include the M-4, M-15, AKs and such. So, you might have fun with that.
Where is there a list of mods for this? I might be vary game for this.
To bad its not OLD school gear LOL. Like those forgotten things like FN49, bm59 or mas 49. Ok I am weird. I keep playing with the idea of whipping up a wonky old school battle rifle mod. But I do not think there would be much interest. Last time I modded for BIS was OFP way way way back when. But that is something else.
Where to get mods and what time?
The arma 3 single player has gotten some love a few updates back. I was replaying the single campaign and there where some marked improvements. On sale and on the fence, you really should give it a go. Despite the annoying sci fi crap there is some fun in the default.
