Our comp bag is the product of countless redesigns and a realization that compact and simple can be very effective when executed correctly. With two extra grippy sides and our unique fill, this bag will literally bring as much stability as an obstacle has to offer. Your rifle effectively becomes attached to the obstacle by friction. The straps aid in stability when looped over the rifle but their main function is allowing you to move without carrying the bag between obstacles. The unstrapped version will feature carry handles on either end. We can do an arca clamp on the bag but have not tested that configuration yet. We suspect it may reduce the contact surface between the rifle and the bag, reducing the effectiveness of the grippy surface.
