ABSTRACT:
A two-piece dovetail mount for a firearm formed with a vertical centerline split. The mount includes first and second members that are fastened together by threaded fasteners. The upper region of the mount forms an industry standard dovetail mount for a sight. The lower region of the mount provides a clamping region for holding the mount onto the firearm. The two members of the mount contact the firearm at the lower region and contact each other at the upper region when being fastened together by the threaded fasteners to define a downwardly opening gap therebetween. When the mount is tightly clamped onto the firearm, the gap remains between the two members at the bottom region, just above the firearm. The gap ensures that an adequate clamping force is applied to hold the mount onto the firearm and permits the mount to be further tightened after the firearm has been fired a number of times. The gap also provides an airflow channel to promote cooling of the mount and firearm, and accommodates differences in the coefficients of thermal expansion between the firearm and the mount. The mount includes an integral recoil absorbing mass abutting a rearward portion of the receiver of the firearm to transfer the recoil force into the mount.
