I'm going to be primarily getting into Milsim, and as time goes on I'll obviously expand my arsenal of guns when my budget allows for it. Currently I'm looking at more outdoor play than indoor so I think the gun should be fine. it has a 15 inch barrel, and in the video review it seems like it's an appropriately sized weapon, plus I'm a pretty big guy, I'm 6'2 and have relatively long arms, my playstyle is more of a accuracy>rush type of style. Not necessarily sniper-like because I want to actually have some action instead of sitting around not shooting anybody. So on top of that, getting into Milsim now that the Gun is covered, should I be looking at a Plate Carrier, BDU's - Woodland, a Radio, Helmet, Goggles, and mask? Assuming there's a basic Milsim start reccomendation and I don't want to be substantially undergeared to where it's not as enjoyable as it should be. Trying to gather enough money to be able to be ready for Operation Irene in Detroit.

Yeah, I'm going to look into the AR that I have it's a BlackWater 15, can't even seem to find any trade marking on it so I'm likely going to just open it up look into it a little bit, and decide whether or not I want to go into an up-gradable platform, like a G&G, or just jump into a gun like a Are Amoeba Series. Either way I'm looking at about a budget of $400 so for the best optimal performance for a singular gun what should I do?
