Catch22 V2 Bolt Catch$49.95
When a standard AR-15 is converted to .22lr through a conversion bolt or replacement upper, the bolt catch stops working. The Catch22 regains that bolt catch functionality when using a .22lr bolt.
When used with CMMG and Black Dog style magazines (with the follower that sticks up above the mag), they allow a the bolt catch to be manually engaged/disengaged.
When used with S&W 15-22 magazines (and a shim) they allow the bolt to be held back after the last shot which provides a true last-round-hold-open like a standard AR.
Please see the "Magazine Compatibility" and "Bolt and Upper Compatibility" sections on the main page for more information around making the Catch22 work with your rifle's setup.
The Catch22 V2 allows tool-less installation/removal and slides over a stock AR-15 bolt catch to work with the .22lr bolt and/or upper. This allows you to easily swap between calibers without the need for any tools.
When the upper receiver is raised from swapping over to your .22lr bolt, just slide the Catch22 V2 over the stock bolt catch and you're ready to go.
