Installed quick and fit perfect - Juggernaut Tactical California Compliant AR-10 Magazine Locking Kit

The package came quick. I used this to make a ca legal rifle. The kit installed in just a few minutes with the right tools. The kit does not allow the bolt to lock open to the rear after last round. A mag change is quick without learning any special techniques. The rear take down is locked in place and can’t be opened up more than a 1/4” once installed.
