The Boonie Packer Better-Mag S&W .22 Rimfire Magazine Adaptor allows AR15 .22 conversion shooters to use S&W M&P 15-22 magazines. The ultra reliable last round hold open activation and easy to load thumb assist made the S&W magazines the obvious choice for this adaptor.

The adaptor is engineered to the same mil-spec requirements as the receiver that it will be sitting in to ensure a perfect fit.*This system will not work with Chiappa, DPMS and Tactical Solutions AR15s.
