This is a firearm — here's how it works
- Order online. Pay in full; we ship it from our warehouse into the shop.
- We receive it. The firearm ships to us (or your chosen FFL) — never to your door.
- DROS & the 10-day wait. California background check and the mandatory 10-day waiting period begin at the counter.
- Pick up & transfer. Bring valid ID and required documents; we complete the compliant transfer.
Description
The Winchester Super X4 is built for the marsh with tough conditions in mind. The SX4 is based on the bullet proof Active Valve gas operating system that was the core foundation of both the SX3 and SX2. The Active Valve has been tested, tried, and tweaked to perfection to make it the most trusted autoloader in the marsh. Includes three Invector choke tubes- full, modified and improved cylinder and sling swivel studs.

California compliance
Every firearm sale runs through the standard California process: an in-person DROS background check, the mandatory 10-day waiting period, a valid Firearm Safety Certificate (FSC), and proof of California residency. The 11% AB 28 firearms excise tax is collected at checkout and shown as a separate, non-taxable line.
