Overview

This replacement spring is intended for setups that need reduced bolt catch resistance to help softer sprung magazines engage the catch more consistently after the last round. It is described as a direct substitute for the stock bolt catch spring and is meant to work with the Catch22 in compatible applications. The product notes cite magazines such as the CMMG Gen2 and KRISS Defiance DMK22 as examples where a lighter spring may be useful. It is a simple, purpose-built part for shooters tuning their rimfire setup for reliable bolt catch function without changing the rest of the system.
