Overview

Designed for AR-15 rifles converted to .22 LR, this bolt catch is intended to restore bolt-catch function that can be lost when using a conversion bolt or replacement upper. It serves as a direct replacement for the standard bolt catch and is described as working with most common .22 LR conversions. Installation is straightforward, requiring removal of the bolt catch roll pin and substitution of the original .223 catch with the Catch22. For shooters who want a more practical way to keep the rifle in a clear condition at the range, it offers a purpose-built solution without relying on an empty magazine.

Considerations & Trade-offs

  • Designed for AR-15 rifles converted to .22 LR, so it is not a general-purpose bolt catch for standard .223/5.56 setups.
  • Compatibility is stated as working with most common .22 LR conversions, which leaves some conversion bolts or replacement uppers unverified.
  • Installation requires punching out the bolt catch roll pin, so it is a parts-swap rather than a drop-in accessory.
  • It is intended to restore bolt-catch function in a converted rifle, but it does not change the underlying limitations of the .22 LR conversion itself.

How is the Catch22 V1 installed?

Why would a hunter or shooter want this instead of relying on a magazine that holds the bolt open?
