This limited production Bone GTR has a machine finish with semi gloss anodizing giving it a unique ribbed texture and satin look. There were less than 50 of these produced. 
 
Ergonomically designed and 3D machined to create a comfortable, universal and purpose built trigger shoe. Everyone has their own preferred method for shooting fast but traditional trigger designs only give you a thin surface to work with.
 
 The Bone GTR was purposefully designed to provide three separate surface areas to comfortably accommodate the most popular shooting styles, with a weight of just 3 grams..
