B5 Systems
The B5 Systems Modular Picatinny Stock in Olive Drab Green is a proven, ergonomic AR platform stock built for shooters who demand adjustability and durability in a single package. This isn't a budget stock that forces you into one position—it's engineered to adapt to your body, your gear, and your shooting style, whether you're running a 3-gun match, hunting, or training at your local range. The modular design pairs a solid composite body with steel hardware and a folding hinge, giving you the control over length of pull and cheekpiece height that makes the difference between a good shot and a great one.
What sets this stock apart is the combination of real adjustments that matter. The length-of-pull adjustment lets you dial in your ideal grip distance without buying multiple stocks or running shims. The spring-assist cheekpiece adds roughly half an inch of vertical adjustment—crucial if you're running variable optics, a red dot mounted high, or just need to shift your head position between prone and standing. The nonslip buttpad keeps the stock in place against your shoulder, and the ambidextrous quick-disconnect mounts mean left- or right-hand sling users aren't left out. The integrated left-side steel folding hinge is robust and doesn't rattle.
Built from durable composite materials with color-matched steel hardware, this stock is made to outlast trends. It attaches to any AR-pattern lower via standard 1913 Picatinny mounting and works with all common buffer tubes. Olive Drab Green blends naturally in the field while remaining practical in any tactical or sporting context.

Yes. The stock features a collapsible 2 1/4" length-of-pull adjustment so you can customize your grip reach. The spring-assist cheekpiece adds approximately 1/2" of height, giving you flexibility to clear optics or shift your sight picture without replacing the stock.
The integrated folding hinge is on the left side, and the ambidextrous quick-disconnect and fixed sling mounts work for both left- and right-hand shooters. You're covered regardless of your firing hand.
The cushioned, nonslip buttpad resists sliding against your shoulder during recoil and provides comfort during extended shooting sessions. The textured surface keeps the stock stable during shouldering.
