AR22 Bolt Catch Reduced Power Spring (for Left Handed Uppers on RH lowers)

If running a LH upper on a RH lower, the standard bolt catches will interfere.  This catch has been modified to make left handed uppers work on right handed lowers. The AR22 bolt catch enables last round bolt hold open when used with 15-22, Kriss, or CMMG Gen 2 Mags (with our upgraded springs – click here).  Manual bolt catch activation will work regardless of mag type (or even without a mag installed). Compatible with the following bolts/uppers: BoreBuddy, CMMG, PSA, RTB, Rock River Arms LAR-22, and BoreBuddy/CMMG conversion kits. Compatible with the following magazines: Kriss AR22, 15-22 (with magwell adapter or stick on magazine spacer), or CMMG Gen 2 (with our upgraded springs – click here) May be incompatible with the Magpul B.A.D. lever – official determination coming soon.
