The SCAR 20S is built around an extended monolithic aluminum upper receiver with a continuous MIL-STD-1913 top rail featuring T-markings for repeatable setup. The quad-rail forend adds mounting space on all sides, and the stock includes an accessory rail under the toe for stability aids.
Its 20-inch heavy-profile barrel and 1:12 RH twist are matched to a reliable short-stroke gas piston action for consistent performance with 7.62x51 NATO. The side charging handle keeps manipulation intuitive while maintaining a stable shooting position.
A factory Geissele Super SCAR two-stage trigger provides a clean, predictable break. The rifle uses SCAR-H/17S pattern detachable steel magazines and has a 20+1 capacity, with both 20-round and 10-round mags included.
The fixed precision stock offers an adjustable cheekpiece, length of pull, and buttpad on twin guide rods, allowing fine-tuned fit. A rubberized finger-groove pistol grip supports a solid hold, and the Flat Dark Earth finish ties the package together. Made in the United States.
