We’ve hit the nail on the head many times, but here we go: CA passed a bunch of stupid laws concerning how assault weapons are defined, so the bullet button is no longer a qualifying way to keep your AR 15 CA-compliant. Now, your AR 15’s magazine is only considered “fixed” if it can only be removed by breaking open the upper and lower receivers to remove it. Poo-poo. But that’s okay because the new ARMagLock makes this a cinch! Let’s review the ARMagLock and how it works:
How The ARMagLock is Made
The ARMagLock is a simple but sturdy little piece of equipment. The actual magazine lock itself is a single piece of aircraft-grade aluminum and it includes two new takedown pins. The rear takedown pin comes with a finger loop for easy manipulation. The ARMagLock takes the place of the standard magazine release and it doesn’t interfere with any other parts in the lower receiver.
If you’re building a new AR 15 in CA, pick up the Classic Lower Parts Kit. It includes the ARMagLock and ensures your lower and rifle are 100% legal.
You can still use any standard drop-in trigger with the ARMagLock, too. We recommend looking at the new RA-140 Super Sport, just in case you wanted to upgrade your trigger while you’re in there installing the MagLock. Installing is a cinch, by the way, and we even provide video instructions here.
How the ARMagLock Works:
The bullet button did let you keep the upper and lower receivers intact – all you had to do was push a small, recessed button inside the magazine release (accomplished only with a tool and not your finger, a critical requirement of the old law). But now, with the ARMagLock, the magazine release only works once you break open the receivers. This is how CA now defines what a “fixed” magazine is.
- Pull the included rear takedown pin (makes break-open almost instant)
A key component of how the ARMagLock works lies in perhaps its simplest component: The quick-release rear takedown pin. It’s a nifty device for easy disassembly whether you buy the MagLock or go featureless. Instead of jamming a screwdriver, multi-tool, or the tip of a 5.56 round into your receiver, you just loop your finger and pull. It’s kind of like a grenade pin (sorry if that triggers any CA legislators).
- Once the pin is pulled and the receivers separate, the magazine release can be pressed
Simple as that! Technically, this reverts your bullet-button-affixed AR 15 back to a more regular function when considering the magazine release itself. No more fiddling with tools or finding a pointy thing to press that tiny, annoying bullet button. The ARMagLock’s over-sized magazine release makes pressing simple and intuitive, and you can even use a BAD lever to make it ambidextrous.
- Pressing the magazine release drops the magazine in regular fashion
Pretty self-explanatory, just drop your empty magazine! Once your magazine is dropped, close your AR 15’s receivers back together and push the takedown pin back in. This should only take you a second or two once you’ve mastered it.
- With the weapon closed, insert a new magazine
Again, super-simple! Your new magazine will be loaded and locked in (“fixed”) just as it would on any regular ole’ rifle – the only difference is you must break the receiver back open if you want to remove it.
The ARMagLock is compatible with all standard AR lowers, including our billet 80% lower with threaded rear takedown pin hole(and it comes in an AR-10 version).
Clearing a Malfunction with the ARMaglock
Clearing a malfunction with any fixed-magazine weapon can be a pain, but the process is simple for any AR 15 equipped with the ARMagLock. There are generally three ways to clear a double-feed, widely considered the most difficult and dangerous malfunction:
- Pull both takedown pins and remove the upper from the lower
- Remove the magazine base plate to empty the magazine
- Lock the bolt and use an Allen key to remove the ARMagLock
