ASG Olsztyn gives his take on the SRU Precision SR-BUP-AR which is available for some time now. This SRU bullpup kit transforms your standard Tokyo Marui M4 into a highly customizable Tavor-inspired assault rifle. While retaining the Tavor's iconic look, it enhances ergonomics, expandability, and versatility. The kit boasts user-friendly features like a flat trigger, enlarged magazine release, and side cocking handle, all improved for gloved use.
