The MP BSL Arm Brace HK94/MP5 is a durable, lightweight, collapsible arm brace designed to aid the single-handed employment of HK94/MP5-pattern pistols. The MP BSL incorporates Magpul design and engineering to enhance brace functionality and provide a robust feature set for MP5-pattern pistols, all while maintaining the iconic aesthetic of the platform. Constructed of our proprietary polymer and featuring a tool-less adjustment system that makes it easier to deploy and collapse the brace, the MP BSL is extremely durable with enhanced ergonomics. The integrated QD sling attachment, combined with ample surface area for lateral forearm contact, dramatically increases stability while firing. An M-LOK slot is included on the MP BSL for added sling mounting options. Not compatible with HK91/G3 pattern firearms. Made in the U.S.A.
