Catch22 .22lr AR-15 bolt catch

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. 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.

AR-15 Catch22 S&W 15-22 magazine adapter (clip-on)

The AR Catch22 clip-on magazine shim can clip right onto your lower for a quick and easy way to shim the magazine and take up the slack in the mag well. The clip is easy to install and remove and it allows you to use your standard 15-22 magazines in your AR without any modification. With the 15-22 magazine adapters, the S&W 15-22 magazine will work great with the Catch22 to provide true last-round-hold-open functionality.  If you are using a Kriss Defiance DMK22 which already comes with a bolt catch, you can use these adapters to use the 15-22 magazines instead of the Kriss magazines. This can be helpful as the 15-22 magazines are more consistent for bolt-hold-open and they come in higher capacity than the Kriss magazines.  One adapter is needed per lower.   For international orders, please visit our partner's page at https://riflemags.co.uk/

AR-15 lightened bolt catch spring

Magazines like the S&W 15-22 have a strong enough spring to solidly engage the bolt catch after the last round is fired. Some magazines like the KRISS Defiance DMK22 need a bit of help to consistently engage the bolt catch.   This spring is a direct replacement for the stock bolt catch spring and will allow you to use the DMK22 magazines with the Catch22. There aren't any adverse effects from switching to the lighter spring.  For international orders, please visit our partner's page at https://riflemags.co.uk/
