The F-29 S.C.R. Spetsnaz is a customized version of F-28 S.C.R. Spetsnaz forces prefer to make manual customizations to their weapons, which, while making for a slipshod appearance, improves the base functionality of the arm. This model sports a modified firing chamber and improved barrel, resulting in higher bullet velocity, stopping power and accuracy, at a small cost of increased recoil and capped firing rate. A slightly smaller magazine (fitted to make space for other improvements) has been countered by an upgraded reload mechanism.
