California compliant ar-10 magazine locking kit - Juggernaut Tactical California Compliant AR-10 Magazine Locking Kit

Easy to install same as the AR-15 kit, but does not work the same on my .308. The takedown pin works fine to create the needed separation to release the magazine, but I have to close the separation of upper and lower and manually push the pin back in place to secure everything. My AR-15 kits are spring assisted and only need to push down the upper and "click" work as described. Not sure if I need to make adjustments to any joining surfaces or detent spring tension to allow to function as designed.
