California Rifle
Compliance Guide

Cut through the confusion. Two paths, clearly explained - so you can build legally and confidently.

Step 01 - Choose Your Path

Two Ways to Stay Legal

California law requires your rifle to either remove prohibited features OR lock the magazine in place. Click each option to learn more.

01
Featureless Build
Remove the features, keep the magazine release
✓Standard magazine release - fast reloads
✓Run detachable mags legally
✓Works with standard capacity magazines
✗Different grip ergonomics
✗Fixed stock position
✗No flash hider
02
Maglock System
Keep your features, fix the magazine
✓Keep your pistol grip
✓Keep your collapsible stock
✓Keep your flash hider
✗Magazine changes require opening the action
✗10 round magazine limit
✗Slower reloads

Featureless Build - What Changes

3 Parts to Replace
Replace
Pistol Grip
Swap to a featureless grip. The web of your trigger hand cannot rest below the top of the exposed trigger - that's the legal line. Our grips are specifically designed to stay on the right side of it.
Fix
Collapsible Stock
A collapsible stock is prohibited. A fixed stock is not. Our stock stop locks your adjustable stock in place - you keep your existing stock, it just can't collapse. Simple and reversible.
Replace
Flash Hider
Flash suppressors are prohibited. Muzzle brakes are not. The difference is function - brakes reduce recoil and muzzle rise, suppressors reduce visible flash. Our kits include a compliant muzzle brake.
The Payoff
With all three changes made your rifle can legally use a standard detachable magazine with a normal magazine release in California. Faster reloads, no opening the action, and you can run any magazine you legally own.

Maglock System - How It Works

Keep All Your Features
A maglock replaces your rear takedown pin and bolt catch with modified parts that lock your magazine in place while your receivers are closed. Here's the reload sequence:
👍
01
Press the takedown pin button with your thumb
↕️
02
Upper and lower slightly separate - action opens
📤
03
Magazine release is now functional - swap mag
🔒
04
Close receivers - maglock re-engages automatically
Which Maglock System Should You Choose?
Most Popular
ARMaglock Gen 4

Which Path Is Right For You?

Answer one question and we'll point you to the right kit.

Quick Recommender

What matters most to you?

→ Featureless Kit Is Your Move

You want speed and simplicity. A featureless build lets you run your magazines exactly like you would in a free state - standard release, normal reloads. Our kits come in three tiers for AR-15, AR-10, and AR-9.

→ Maglock System Is Your Move

You've already got a rifle set up exactly how you like it and don't want to change the feel. A maglock keeps everything intact - just adds a step to the reload. Our ARMaglock Gen 4 is the best choice for most builds.

→ Start With Featureless

If you're new to California compliance, featureless is the easier path to understand and install. Our Budget Kit is a great starting point - everything included, clear instructions, and you're legal in under an hour.
