Frequently Asked Questions
Will the B5 Systems SOPMOD Stock fit my AR-15 lower receiver?
Yes — this stock is designed specifically for mil-spec carbine receiver extensions (buffer tubes). It will not fit commercial-spec buffer tubes, which have a slightly larger diameter and different taper. If you're unsure which spec your lower uses, check your receiver extension diameter: mil-spec measures approximately 1.148" outer diameter at the rear.
What can I store in the compartments, and are they truly waterproof?
The dual storage compartments are water-resistant (not fully waterproof) and sized to hold small items like CR123A batteries, a folded cleaning patch, a spare bolt firing pin, or a memory card. They're a great spot for mission-critical backup gear you want close at hand without adding bulk to your kit.
How does the B5 Systems SOPMOD compare to a standard mil-spec stock?
The SOPMOD builds on the basic mil-spec collapsible stock with several meaningful upgrades: the anti-rotational QD sling mounts eliminate the spin common on sling swivel cups, the SureGrip latch significantly reduces buffer tube rattle, and the cushioned no-slip buttpad improves shoulder comfort during extended range sessions. It's a direct drop-in upgrade with no additional tools or modification required.
