I received the Para Viper along with a Firefly and they are both great figures with lots of nifty, useful accessories.
In fact, the Joes are growing on me, thanks to Spudafett for getting me infected.
The Para Viper's long rifle is a WW2 German 1st model FG42, the only German personal weapon specifically made for the paratroops. The only difference is that Hasbro gave the FG a folding stock which the real thing didn't have. It sported a reversable needle bajonet and a folding stock as it was thought to double as a light machinegun and in combination with a scope, as a sniper rifle.
Needless to say, it wasn't really any of that. Could have been great, had it been constructed for the short cartridge...okay, I'm stopping here before I bore you guys to death with all this historical trivia.
Still, a cool weapon for an action figure.
I've cut the mag pouches away from the Viper's parachute harness and they will look very good as pouches on a Clone trooper, Mandalorian, Rebel Commando, etc. The parachute helmet has a certain Star Wars look to it so I think it will be great for any civilian, Rebel or even Republic or Imperial pilot.
On mine, I'm probably going to re-sculpt the back of the lower legs so the figure can be used without the fins attached and sand off the collar of his shirt so armor will fit more snugly over him.
