**NOTE – Please read the FAQ below regarding adjustment of your ejector before use and ensure you re-assemble with Loctite or similar threadlocker to prevent screws from backing out over time.


**Internal factory installed feature forces the upper to be opened slightly to allow the magazine release to function.  No need for aftermarket mag locks, etc.  We recommend using the BAD Quick Release Rear takedown pin on our California Compliant pistol caliber lowers.  You can read more about them here: BAD Quick Release Rear Takedown Pin
