Ar Catch22 LIGHTENED BOLT CATCH SPRING LIGHTENED-SPRING

Less catch resistance for use with softer sprung mags

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 CMMG Gen2, and 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 these magazines with the Catch22. There aren't any adverse effects from switching to the lighter spring.
