B5 MODULAR PICATINNY STOCK WOLF GREY

The B5 Systems Modular Picatinny stock brings adjustability and ergonomic control to your AR platform rifle. Built for shooters who want a collapsible stock that adapts to their body and shooting position without sacrificing durability or reliability, this Wolf Grey composite stock mounts directly to any Picatinny rail via standard 1913 pattern attachment. Whether you're running a short-barreled rifle that lives in a bag, a precision build that doubles for hunting and range work, or a carbine that needs to fit multiple shooters, the B5's modular design lets you dial in comfort and control.

What sets this stock apart from basic adjustable options is the spring-assisted cheekpiece. Instead of a fixed cheekrest, you get 1/2 inch of height adjustment to bring your eye exactly where it needs to be behind your optic—a real advantage when switching between magnified scopes, red dots, and different sight heights. The length of pull adjustment spans 2 1/4 inches, letting you tailor the stock to your arm length and shooting gear (lighter loads or heavy winter jackets both factor in). That range of adjustment makes one stock functional for multiple rifle setups or shooters.

The steel hardware and composite materials handle field use without complaint. An integral left-side folding hinge works for storage and transport, while dual sling mount options give you flexibility: fixed mounts for traditional two-point setups and steel quick-disconnect mounts with anti-rotation indexing so your sling stays where you put it. A cushioned, nonslip buttpad keeps the stock seated under recoil and won't slide on tactical gear or a shooting bag.

Frequently Asked Questions

What rifles does this stock fit?

Can I adjust the cheekpiece and length of pull independently?

Yes. The spring-assist cheekpiece is separate from the length of pull adjustment, so you can set cheekrest height and stock length to suit your build and shooting style independently.

Does this stock come with mounting hardware?

The stock attaches via 1913 Picatinny mount; ensure your receiver extension has a Picatinny rail. Sling mounts are integrated—both fixed and QD options are included.

The stock includes both fixed mounts for permanent two-point sling attachment and steel quick-disconnect mounts with anti-rotation indexing, giving you flexibility in how you rig your sling.
