US12638256 - Breaching tool
A receiver assembly for a breaching tool has an upper receiver with female fittings in the form of side flanges at the front and back that connect to the lower receiver's male fittings in the form of a front center post and back sidewalls. The post fits between the front side flanges and the back sidewalls fit between the back side flanges. Apertures in the front side flanges are aligned with an aperture in the center post, and apertures in the back sidewalls align with the back side flanges, and takedown pins extend through the aligned apertures. The flanges can include cutback angles which engage with a front riser in the lower receiver's sidewalls and with rear bosses extending outward from the lower receivers sidewalls. A protrusion in the upper receiver's magazine well only allows a magazine with a notch at its top, front end to engage with the well.
