Finally a solution for your .22lr AR-15 bolt catch
Please note: The Black Dog Gen 3 magazines WILL NOT WORK with the Catch22. The two pieces can be used together but the magazine will not engage the bolt catch after the last round is fired.
Right now, in order to get a true last round hold open, you'll need to use the 15-22 magazines and adapters.

Here's the latest review of the Catch22 and adapters. Thanks brassburnz for the review!
