“CA” Compliance Option/Magazine Restrictions

Rooftop Arms DOES ship to California as well as other states/jurisdictions with detachable magazine laws. If you would like a Rooftop Arms rifle to be made “CA” Compliant, we will install a 4th Generation AR Maglock Kit with a silver Kingpin. There is a $150 fee for this change. Select the “CA” Compliant option in the drop-down menu on the firearm you are purchasing. We cannot offer substitutions as we have partnered with AR Maglock directly and we feel they offer a great product. You can change the type of compliance device if you like once you take possession of the firearm from your local FFL. If you live in a state with magazine capacity restrictions, we cannot ship our typical magazines that are included with our firearms. In this case we will substitute Lancer L5AWM 10/30 round magazines for AR15 models, Lancer L7AWN 10 round magazines for AR10 models, and Glock OEM 10 round magazines for AR9 models for your order.

AR Maglock Gen 4 Information

AR MAGLOCK Gen 4 – AR-15 (.223 / 5.56) Fixed Magazine Lock and Release Solution (AR MAGLOCK in anodized black components, KingPin in silver).

The Gen 4 and KingPin combo allows for minimal separation (action disassembly) of the upper and lower receivers. The KingPin holds the upper receiver from flying open when disassembling the action.

Just a simple push on the pin with your thumb opens the action for mag changes, then automatically re-locks when you push the receivers together.

The Gen 4 benefits:

– New set screw on locking arm, allowing for adjustment to ANY receiver width including billet, composite, or 80% non-mil-spec receivers.
– Allows for “free state” adjustment when traveling outside California. Just reset the set screw to the end of the post and the locking arm will work just like an OEM magazine release button.

The KingPin benefits:

– Retain your critically important bolt catch
– Seamless double feed clearing
– Bolt hold back on last round
– Fast magazine changes (as fast as OEM mag release button)
– Clear access to your safety selector
– Easy removal from the receiver to fully open the action
