Petra Adjustable Buffer Weight System


This adjustable buffer system was designed for the Petra 300wm, and allows additional weight adjustment for shooting suppressed or unsuppressed depending on the weight combination. The buffer comes with 3 sets of weights, aluminum, steel, and tungsten that can all be interchanged in small or large increments of weight to slow or speed up the buffers travel. This system can be used by itself or in addition to an adjustable gas key. (this will work on all Petra models, past and present.)
