The Rearden 10021 FHD (HT) 0.375 1/2-28 Square Plan B flash hider is purpose built for shooters who want a compact, efficient muzzle device that integrates cleanly with modern suppressor systems. Machined from durable 17-4 PH H900 steel and finished in a heat-treated gold tone, it offers a refined look while maintaining the strength needed for repeated range sessions.

This model uses a 1/2x28 thread pitch with a square shoulder and a .375 bore, making it a strong option for compatible rifles that will host Atlas, Atlas XL, or Plan B mounting systems. Its pronged design helps disrupt muzzle flash while the precision machining supports consistent alignment when used with compatible accessories. Rearden is known for thoughtful engineering and solid manufacturing that appeals to shooters who value reliability and clean, functional design.
