California Rifle Compliance — Complete Methods Guide

WBT has configured rifles for California since 2012. The work is done at our own warehouse in Yuma, Arizona, and the rifles are picked up or transferred through our La Mesa store or the California gun store you choose. This guide is written for buyers, not lawyers. It is not legal advice, and California firearm law changes; when it matters, our staff will walk you through the specifics for your purchase.

The three ways a rifle can be California-legal

1. Factory compliant

Some rifles are legal in California exactly as the manufacturer builds them. Bolt-action, lever-action and pump rifles fall here, along with many rimfire and traditional-style semi-autos (a Mini-14 with a standard stock, for example). Nothing is changed. We still inspect each one before it ships.

2. Fixed magazine

A "fixed-magazine" rifle keeps the features California restricts, such as a pistol grip, an adjustable stock and a flash hider, because the magazine cannot be removed while the action is closed. In practice the magazine release is replaced with a device that only lets the magazine out when the rifle is opened.

• AR MagLock Gen 2 is our standard fixed-magazine conversion for AR-pattern rifles. To reload you pop the rear takedown pin, tilt the upper open, swap the 10-round magazine, and close it. The optional KingPin upgrade makes opening the rifle faster. We install the Gen 2 rather than the newer Gen 4 MagLock on mil-spec lowers on purpose: the Gen 4 attaches to the rifle differently, and in our experience it has not stayed adjusted as reliably over time. The Gen 2 has held up across years of builds, so that is the one we stand behind. On lowers that are not mil-spec and will not accept the Gen 2, we may use the Gen 4 instead.
• CompMag is a fixed 10-round magazine that stays in the rifle. You load it from the side through a loading port, one round at a time, so the rifle is never opened to reload. It fits most rifles that take a standard AR-15, AR-10 or AK-47 magazine (bullpups excluded).
• Juggernaut Tactical Hellfighter is an alternative fixed-magazine kit for AR-pattern rifles that works differently from the MagLock. It replaces the bolt catch with a mechanism that locks the magazine in place, and includes quick-release takedown hardware, so it covers what the AR MagLock and KingPin do together in one kit. Reloading is the same idea: open the action, swap the 10-round magazine, close it.

What it feels like to shoot: the rifle looks and handles exactly like it does everywhere else. With MagLock or Hellfighter, reloads are slower and done in two steps instead of one. With CompMag, you top up the magazine in place instead of swapping it.

3. Featureless

A "featureless" rifle takes the opposite approach. It keeps a normal detachable magazine (10 rounds or fewer) and a normal magazine release, and instead removes every restricted feature:

• No pistol grip. The standard build uses a grip fin (a wedge behind the grip) or a Kydex grip wrap. Your thumb rides on top rather than wrapping around. On AR-pattern rifles, if you want something more comfortable than a fin, purpose-built featureless grips such as the Sparrow Dynamics grip, the Juggernaut Tactical grip, or the Strike Industries MegaFin can be added to your order. These AR grips do not fit AK-pattern rifles; AKs use an AK-specific grip fin.
• No adjustable stock. Collapsible stocks are pinned in one position. Folding stocks are a separate issue: they are almost never allowed in California with either method, because a folded rifle drops under the 30-inch minimum overall length, so a folding stock is pinned open or replaced no matter how the rifle is built.
• No flash hider. We remove it and install a thread protector. Muzzle brakes and compensators are allowed, so you can upgrade to one if you like; our muzzle brakes category has over 500 to choose from, and we install it with the build.
• No vertical foregrip. Angled foregrips and hand stops are fine.

What it feels like to shoot: reloads are fast and familiar, and you can drop the magazine with the button like anywhere else. The trade-off is the grip, which takes most people a range session to get used to.

Why some rifles can only be built one way

This is the question we get most often, and it's the reason you'll see a choice of configurations on some product pages and a single configuration on others. The method is dictated by the rifle's hardware, not by preference.

• Ambidextrous controls can rule out MagLock. Rifles with ambidextrous bolt releases or magazine releases often don't have room for the MagLock mechanism, so those rifles are built featureless.
• A pinned-and-welded flash hider usually means fixed magazine. If the manufacturer permanently attached a flash hider to reach legal barrel length, the rifle is normally built fixed-magazine so it can keep that flash hider. On a case-by-case basis we can remove the factory pin-and-weld and install a new muzzle device so the rifle can go featureless; the labor is $150 plus the cost of the muzzle device. Call us before you order if you want that done.
• Folding stocks are almost never allowed in California, even on a fixed-magazine rifle, because folding drops the rifle under 30 inches overall. They are pinned open or replaced. A collapsing stock is different: it stays adjustable on a fixed-magazine build and is pinned in one position for featureless.
• AK-pattern rifles have a one-piece receiver. The MagLock works by opening the rifle at the rear takedown pin to swap the magazine, and an AK has nothing to open, so the MagLock approach is off the table. That leaves two routes for an AK: featureless (grip fin, fixed or pinned stock, flash hider removed), which is how we build most of them, or a CompMag, which stays in the rifle and loads from the side so the rifle never needs to open.
• Bullpups (Tavor, X95, AUG, Hellion, PS90, Desert Tech MDR, Kel-Tec RDB and RFB) are short by design, so they get a pinned-and-welded muzzle extension to reach California's 30-inch minimum overall length, plus a grip wrap or fin. The extension is permanent, so the muzzle device on a bullpup cannot be changed.
• Pistol-caliber carbines vary widely; some take a standard fixed-magazine kit, others only work featureless.
• Other platforms are built one way. SCAR, PTR/G3-pattern, FAL, Kel-Tec, M1A, Thompson, Vector, Sub-2000 and similar rifles are built featureless in the one configuration that works for that design (grip fin or Kydex grip wrap, pinned stock, flash hider removed). They are not offered the other way and do not take the upgrade parts made for AR-pattern rifles.

On AR-15 and AR-10 pattern rifles, and some AKs, you can also add upgrade parts to your order (see the FAQ below). On the other platforms the configuration shown is the one we offer.

Which should I choose?

Both are legal to own in California when done correctly, and both are reversible by a gunsmith if you ever move. Shooters who compete or train a lot usually prefer featureless. Shooters who want the rifle to look the way it does in the catalog usually prefer fixed magazine.

Shotguns

Most semi-automatic and pump shotguns are legal in California as built. The exceptions are semi-auto shotguns with a detachable magazine or with both a pistol grip and an adjustable stock, which we configure or exclude as needed. Shotgun product pages state the configuration the same way rifle pages do.

• Pay in full, put 50% down and pay the balance in 14 days, or finance with Credova.

Frequently asked questions

Can I switch from fixed magazine to featureless later?

Usually yes, if the rifle's hardware allows it. Our gunsmiths can quote the change.

Is a "bullet button" still legal?

No. The bullet button was the old fixed-magazine method and has not been a compliant option for new configurations since 2017. Rifles sold today use MagLock, CompMag or similar devices that require opening the action.

Can I use my existing 30-round magazines in a fixed-magazine rifle?

No. California limits magazines to 10 rounds. Fixed-magazine rifles use a 10-round magazine, and so do featureless rifles.

Does a featureless rifle need a special magazine?

No. Any standard 10-round magazine for that rifle works.

Can WBT make a rifle I bought somewhere else California-legal?

Yes. Have it shipped to us, and we'll configure it and handle the transfer. Fees and shipping instructions are on our transfers page.

Do I need a Firearm Safety Certificate?

Yes, for most buyers. We can administer the test at our store. Details are on our FAQ.

Can I upgrade the compliance parts?

On AR-15 and AR-10 pattern rifles, yes. Our California Compliance Upgrades category lists the add-ons we install at the time of the build: featureless grips (Sparrow Dynamics, Juggernaut Tactical, Strike MegaFin), the KingPin quick-release for MagLock rifles, and more, and muzzle brakes to replace the thread protector are in their own category. Add them to the same order and the rifle ships with them installed. AK-pattern rifles take AK-specific parts only (the AR grips and MagLock do not fit). SCAR, PTR, FAL, Kel-Tec, bullpups and the other non-AR platforms are built one set way and cannot be upgraded.
