Bullet Button For CA Compliant Lowers

  • Drop-in replacement for factory magazine release button retains the magazine in the lower receiver to conform with California Code of Regulations 978.20(a). Prevents rapid magazine removal, so your gun can meet the requirement for a permanent, non-detachable magazine. Installs in minutes.
  • NOTE: If you are buying a complete lower from us to be sent to an FFL in CA, we will automatically install this on your lower when you add this item to the same shopping cart so that the lower is CA compliant when it arrives.


Federal law requires that you be 21 years or age or older to purchase a stripped receiver or frame. If a frame or receiver can only be made into a long gun (rifle or shotgun), it is still a frame or receiver not a handgun or long gun. However, they still are "firearms" by definition, and subject to the same GCA limitations as any other firearms. See Section 921(a)(3)(b). 18 U.S.C. Section 922(b)(1) makes it unlawful for a licensee to sell any firearm other than a shotgun or rifle to any person under the age of 21.

Its ok to put your personal shipping address on your order. We are fully aware that we need to ship your firearm to a licensed firearms dealer and cannot send it to your personal address.

WE DO NOT CONTACT YOUR FFL ON YOU BEHALF. To expedite your order, please have your dealer fax or email a valid copy of their FFL license to us. They will need to reference your first and last name as well as the order number so we can match the it to your order. Legally, we cannot ship your order unless we have this information on file.

FAQ:

QUESTION: What type of magazines will fit in this lower?

ANSWER: The lower was designed to fit and drop free factory Glock small frame pistol magazines. It has also been thoroughly tested with Magpul GL17 9mm pistol magazines to fit and drop free. Although it accepts and shoots other aftermarket magazines (Promag, KCI, Kahn, etc) some slight modification may be needed to get them to drop free from this lower because of the varying width measurement we have seen when checking these magazines to Glock factory specifications.

QUESTION: Do you offer a reliable last round / empty magazine bolt hold open (LRBHO) System for this lower?

ANSWER: YES – After watching several companies try and fail to incorporate a RELIABLE last round bolt hold open (LRBHO) system into their lower receivers we decided to take a different approach and will be incorporating our LRBHO technology (PATENT PENDING) in our matching upper receivers. After rigorous testing and hundreds of hours of research and development we feel that this is the best option for LRBHO on a Glock magazine AR style firearm. Our upper will be compatible with other manufacturers lower receiver that either don’t have a LRBHO or you can scrap the non-working LRBHO out of your existing AR-9 Glock Mag lower and solve the issue of not having a 100% functioning LRBHO.

QUESTION: What bolt carrier group will work with a Glock magazine fed AR-9?

ANSWER: You will need an AR-9 Bolt Carrier Group that has relief cuts to clear the Glock style magazines. Both AR-9 BCG’s that we sell (CLICK HERE for AR-9 BCG’s) will work in both Glock style AR-9′s as well as traditional Colt style AR-9′s. We can also modify your Colt style AR-9 BCG for you to work properly with both systems. CLICK HERE for more details on that service (coming soon)

QUESTION: It seems as though my BCG may be hitting or rubbing the ejector on the lower, how can I fix that?

ANSWER: Loosen the two screws holding the ejector in to where its a friction fit. Ensure the ejector is seated all the way to the rear and all the way down in the pocket. Close your upper onto the lower with the bolt all the way forward. SLOWLY cycle the bolt in and out about 1/4 of the way back a few times then let the bolt close all the way and tighten the ejector screws. They are cupped to get a good grab on the SS ejector, so only hand tight or you risk the chance of bending the ejector over. Any slight rubbing at this point will wear in the ejector after a few magazines are cycled through the gun. If you see excessive rubbing you can also file down the top corner on the left side of the ejector (shooters left)

QUESTION: Do I need to use a special buffer when I build my AR-9?

ANSWER: Although its not technically required, it is advised that you either use a 9mm buffer (longer and heavier than carbine) or a spacer in your buffer tube before you place your spring in. The reason for this is to limit the BCG travel to the rear so it doesn’t come back forward and smash the bolt catch hard enough to break it. The 9mm BCG is shorter than a standard BCG. You can use a carbine buffer with a spacer (WHICH YOU CAN PURCHASE BY CLICKING HERE) or simply stack between $1.25 – $1.75 of quarters in your buffer tube.
