another route, is to either buy/construct a "blanket" or "tarp" type concealment
that's what me and my brother use, i carry the ranged weapon and he uses the SMG, between the two of us we can usually keep our bases covered. the tarp works well because you just throw it over you and your weapon and you have instant concealment. then when you are on the move again, just roll it up and throw it in your bag.
of course this is all dependent on your loadout, if you are a high-speed low-drag type guy then this wouldnt work for you since you would be spending alot of time on the ground.
another upside to a tarp type concealment is that if you need COMPLETE coverage, you can just pull it up over the end of the barrel and yourself, then you should be safe from quick glances.
of course this works best in environments that have alot of vegetation, supplementing real foliage like rogue fox suggested is a very good idea as well
