B5 Systems Collapsible Precision Stock, Black, Medium Length Cheek Riser

The B5 Systems AR-15 Collapsible Precision Buttstock brings a new level of refinement and versatility to MSR platforms. Building on the trusted cheek profile found in the SOPMOD and Bravo stocks, this design adds a fully adjustable cheekpiece and butt pad, offering a refined fit and greater shooter control. Precision dials fine-tune cheek weld and butt-pad height, supported by 10 internal tensioners that lock settings firmly in place. Even in a fully collapsed position, the cheekpiece clears the AR-15 charging handle, maintaining compatibility with compact configurations. Constructed with mil-spec materials and color-matched steel hardware, the stock blends durability with a clean, integrated appearance. A pull-down length-of-pull adjustment lever with a lockout feature allows for quick, secure changes in the field. Fixed sling mounts and steel anti-rotational QD points provide ambidextrous sling setup options, while the cushioned non-slip butt pad enhances comfort during extended use. M-LOK attachment points along the underside offer mounting options for monopods or other accessories, and slots along the top accept an additional cheekpiece if needed for further customization. Purpose-built for tactical rifles, precision builds, and competition carbines, the B5 Systems AR-15 Collapsible Precision Buttstock delivers compact adjustability, reliable performance, and a tailored shooting experience.
