The B5 Systems Bravo Fixed Stock is a mil-spec carbine buttstock engineered for AR-15 and LR-308 platforms where a solid, non-adjustable design fits your shooting style. Built in the USA from mil-spec materials and finishes, the Bravo combines proven ergonomics with practical sling attachment options—making it a go-to choice for precision rifle builds, duty setups, and shooters who value simplicity over adjustability.
What sets this fixed stock apart is its attention to detail. The integrated cheek weld geometry promotes a consistent firing position, while the over-molded steel anti-rotational quick-disconnect sling mount keeps your sling exactly where you want it—no twisting, no drift. Fixed sling attachment points and a no-slip cushioned buttpad round out a design that's equally at home on a range carbine or a purpose-built rifle. Steel hardware is color-matched to your chosen finish for a clean, finished appearance.
Installation is straightforward: the stock mounts via setscrew to any mil-spec carbine receiver extension on AR-pattern rifles. Its compact footprint and modest weight make it ideal for shooters who need a durable, reliable rear assembly without the complexity of an adjustable system. Whether you're building a lightweight hunting rifle, a precision target gun, or a duty carbine, the Bravo Fixed Stock delivers American-made quality without compromise.

Yes, the Bravo Fixed Stock is designed for both AR-15 and LR-308 platforms. It mounts via setscrew to any mil-spec carbine receiver extension, which is standard on both rifle types. If your receiver extension is mil-spec diameter, the stock will fit.
This is a fixed-length stock with no adjustment capability. It's lighter, simpler, and offers fewer failure points—ideal for shooters who've dialed in their preferred length of pull or who prioritize durability and reliability over configuration flexibility. The integrated cheek weld and sling mounts are optimized for a fixed design.
The stock includes the over-molded steel anti-rotational QD mount point and fixed sling attachment points. A sling is not included with the stock and must be purchased separately.
Installation is done via setscrew onto your carbine receiver extension. No special tools beyond a hex key are required. Ensure your receiver extension is mil-spec diameter before purchasing.
