CA Compliance:
California compliance
- Status: Legal to own in California.
- Configuration: Featureless, built by WBT: grip fin in place of the pistol grip, stock pinned in a fixed position, flash hider removed and replaced with a thread protector (a muzzle brake is an optional upgrade). The magazine release works normally, so reloads are the same as anywhere else.
- Magazine: Standard detachable, 10-round.
- Your options: If this page shows a compliance selector, choose the build you prefer and we configure it that way. If not, this is the configuration we offer by default; on AR-pattern rifles and some AKs a different build is often possible, so ask us before you order.
- Upgrades: Prefer a more comfortable featureless grip (Sparrow Dynamics, Juggernaut Tactical, Strike MegaFin)? See California Compliance Upgrades. Want a muzzle brake in place of the thread protector? Add either to this order and they ship installed.

A note on accuracy. We work hard to keep every listing correct, but specifications, images and compliance details come from many sources and can contain errors or change without notice. Images may show a configuration that is not California-legal. If a detail on this page matters to your decision, call us and we will confirm it against the actual firearm before you order. The compliance information here is general in nature and is not legal advice; California and local laws change, and the configuration described is confirmed at the time of sale. All sales are subject to applicable federal, state and local law and to the buyer's eligibility to purchase.
