B5 Systems Collapsible Precision Stock Long – AR-15/M16 Mil-Spec

The B5 Systems Collapsible Precision Stock delivers a repeatable cheek weld and enhanced stability for precision shooting applications. Designed for shooters who demand consistent eye relief and a solid cheek-to-stock interface, this extended-length stock improves accuracy from supported positions while maintaining collapsibility for transport and storage.

Constructed from reinforced polymer with a rubberized buttpad, this stock fits mil-spec carbine receiver extensions and installs with standard takedown pins. The extended length provides additional cheek contact area compared to standard carbine stocks, making it well-suited for optic-equipped rifles where a higher sight plane requires proper cheek support. QD sling swivel compatible.
