@Mightyjebus - Sadly it is not - you'd have to make a custom one to fit and even then I am quite sure that the 'walls' of the grip would be far too thin and fragile. A fair few people opt to sand and paint the pistol-grip to look like wood - some do it very well. I feared I'd fluff it up so I left it as is! @dFrog - the chestrig is a reproduction of a Rhodesian Bush War Fereday and Sons chest rig - I got it from Varusteleka, Better Pictures:
