For sale. Lightly, barely used. 2015 model. 

Dual tube, 7 + 7 + 1

Older model that is a titanium stainless color and was advertised for maritime use. Gen 2 which is what they are still making today, just not in this color scheme. The silver one they sell is similar but not completely the same color scheme. 

Comes with add ons: bottom grip rail panels, forward stop/grip (for safety), and flip up sights.
