"[AR MAGLOCK allows California AR-15 owners to comply with existing fixed magazine laws, thus avoiding Department of Justice registration.
AR MAGLOCK engages the magazine so it stays “fixed” in the firearm until the action is disassembled, complying with California SB 880 & AB 1135, and Department of Justice regulations.
It is our reasonable belief the AR MAGLOCK complies with New York NY SAFE , Connecticut, Maryland, New Jersey and other states (and other local municipalities such as Cook County Illinois) detachable magazine laws based on our in depth analysis of these laws and regulations.
In an effort to address some consumers concerns related to our website statement “potentiality complaint”… “Potentially compliant” does NOT refer to California as it IS compliant within this state, but it does refer to other states and municipalities with detachable magazine restrictions. Locations such as Cook County IL have ordinances that make our product potentially compliant also, but we leave it to the end consumer to make that judgment based on their knowledge of their local laws and regulations. We can’t be expected to know all of the regulations in every place that the AR MAGLOCK can be used.
With few exceptions, competing products to the AR MAGLOCK have an inherent and critical safety issue!
MOST other systems DO NOT allow for the fixed magazine kit to be removed during a double feed firing malfunction in which a live cartridge is jammed in the firing chamber. This is because the bolt carrier group is locked back into the butt stock buffer tube, which then doesn’t allow for the receivers to be separated (open the action), nor can the magazine be removed (because it’s locked), thus not allowing the user to clear the malfunction / live round. This is VERY dangerous.
This is a HUGE safety issue and a critical liability for any entity selling or installing these fixed magazine locking systems, including the OEM’s, retailers and manufacturers.
Many of the OEM’s at the 2017 Shot Show mentioned this concern, and it’s one of the primary reasons most have chosen the AR MAGLOCK system as their solution for California.
The AR MAGLOCK allows you to use the hex wrench to remove the lock kit thus removing the magazine so you can safely clear the loaded rounds from the chamber.
Available for AR-15 and AR-10
There is no denying that AR MAGLOCK is the perfect solution for your
AR-15 and AR-10 firearms.
With registration looming, our product will help you to avoid sending every piece of personal information to the CA DOJ for registration. Registration shall contain a description of the firearm that identifies it uniquely, including all identification marks, the full name, address, date of birth, and thumbprint of the owner, and any other information that the department may deem appropriate.
The AR MAGLOCK is covered by U.S. Patent No. 8,756,845. AR MAGLOCK is THE ONLY licensed device under this patent. Manufacturing, selling, and/or installing ANY other device utilizing an arm contacting the upper receiver which prevents the magazine from being removed until the upper receiver is separated from the lower receiver, is in violation of U.S. patent laws, which will be vehemently pursued and prosecuted as such.]" No returns will be accepted unless we make an error so please specify in comments to seller "AR-15 or AR-10"
