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. A high-mounted rail accommodates various sights, while side and underside rails offer extensive accessory attachment options. Battery space in both handguard and stock caters to both front and rear wiring configurations, and the hollow barrel section allows for personalized front-end customization. Please note disassembly and potential adjustments are required during installation. Compatible with major electric gun standards, this kit elevates your M4 to a whole new level of performance and personalization.
