EXTREMELY RARE GoRuck R+D Research & Development Bullet Ruck 15L v1.1 Two Pocket Extremely rare 15L bullet ruck built during a research and development phase in 2013. This model has some unique features that were not included in later bullet models including an extra row of MOLLE and a second compartment for a hydration bladder. Very unique piece for a GoRuck collector. The backpack is in good condition overall and GoRuck maintains one of the best warranties in the game with the SCARs lifetime guarantee. There are signs of regular use and some flaking of the lamination at the bottom interior of the pack as shown in the last photo. Reasonable offers accepted.
