The “Bravo” model retains all the features of the original SU-16, such as integrated bipod, Picatinny rail, and rotating stock with magazine storage.However, the “Bravo” has a lighter and shorter barrel, about 8 oz. and 2.3”.
The rear sight is hard coat anodized aluminum and adjustable for windage. The front sight, also aluminum, is removable and accepts standard M-16 posts.The SU-16B is not a replacement for the original SU-16 but a compliment for customers that put a premium on light weight and compactness. The “Bravo” type sights can be purchased as a retrofit for SU-16 owners preferring the M-16 system.
