I've had some of Ground Zero Games' snipers kicking around for ages. I've followed my usual colour scheme for them - grey fatigues with green camp splodges, brown armour with green and grey drybrushed camo patches.
It makes a change to have a sniper with a weapon that's something other than along-barrelled version of their normal rifle. In this case it's a laser system as you can see by the power cable and the stubby shape. If you really wanted a long barrel (perhaps to make it easier to tell the sniper apart on the battlefield), the chunky nature of the weapon would make it easy to drill a hole and pop a bit of brass rod in.
I've done a couple of weapon teams with the prone sniper figures, will post them in the next few days when I've had a chance to download the photographs.
