Juggernaut Tactical Hellfighter AR-10 Mod Kit, Stainless

The Juggernaut Tactical Hellfighter AR-10 Mod Kit in stainless steel (part no. JT-HT-PK-CA-10-SS) brings the same California-compliant magazine lock solution built for the AR-15 to the larger AR-10 platform, from Juggernaut Tactical. A modified quick-release takedown pin doubles as a button: pressing it separates the upper from the lower just enough to disengage semi-automatic operation and automatically disable the magazine lock, so the magazine release becomes operable for a fast reload. A simple tap re-closes the upper and re-engages the spring-loaded pin to get back in the fight.

Frequently Asked Questions

Does this fit both back-fed and bottom-fed AR-10 lowers? Yes, the AR-10 kit is built to work with either a back-fed or bottom-fed takedown pin detent.

How does it make magazine changes legal in California? It replaces the standard takedown pin with a modified quick-release pin that, when pressed, disengages semi-automatic operation and disables the magazine lock, satisfying California’s fixed-magazine requirement until the upper is closed again.

Is this a permanent modification to my lower? No, it is a bolt-on solution built around the takedown pin rather than a destructive or machined modification.
