A decent workaround - Juggernaut Tactical California Compliant AR-15 Magazine Locking Kit

Putting aside the fact this device should have never needed to be invented, it does its job very well. It is easy to install and seems pretty durable, at least for moderate use. It can become a bit cumbersome when removing for maintenance and cleaning but is not impossible. My one gripe with this device has to be the tolerances for varying magazine types. When switching magazine manufacturers and material, this device seems to need very minor adjusting to engage the magazine catch properly. Without adjustments the magazines either need a firm slap to seat properly or even not seat at all. This is not a deal breaker when you adjust it properly for whichever magazine type you prefer and let's face it - who doesn't need more magazines? For anyone contemplating purchasing this magazine locking kit I offer this tidbit of information: The last round bolt hold open (LRBHO) is lost when this device is installed.
