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

The B5 Systems Precision Stock Collapsible Long extends length-of-pull for taller shooters or those wearing heavier gear, improving cheek weld consistency and shoulder pocket alignment. The extended length reduces felt recoil and provides a more stable shooting platform for precision rifle setups while maintaining the adjustability of a collapsible design.

Constructed from reinforced polymer with an anti-slip rubber buttpad, this stock installs on any mil-spec carbine buffer tube. The longer length adds approximately 0.8 inches compared to standard collapsible stocks, making it ideal for larger-frame shooters or those running optics that require proper eye relief. Six-position adjustment allows fine-tuning for different shooting positions and clothing layers.
