Rifle - Cobra Officer (reproduction)

This is a New Sculpt-era figure done up in the correct ARAH format. The head of the original figure works just fine with the ARAH parts, and there are ARAH parts available that produce a pretty accurate reproduction of the Neo-Viper as you can see in the recipe below. The Neo-Viper had a variety of colour schemes; this one is based on the original figure's colourations since it has a nice blue uniform as Cobras are wont to do.
