The Scythe STM is a stainless steel version that maintains all of the quality features from the Scythe-Ti but uses different material construction. Its intended for harder use applications due to its durability. The Scythe STM is full-auto rated with no barrel restrictions. Its also modular at one baffle shorter than the Scythe-Ti in its short configuration and two baffles longer in its long configuration for maximum sound suppression. Includes a Bravo radial tool.
