B-Square no-gunsmithing semi-auto pistol mounts integrate with the pistol's original components to assure optimum performance with every trigger pull, superior to any "grip" mounted system. The saddle mounts are a see-thru design and provide minimum slide clearance for a sleek look! Full-length ring rails allow maximum eye relief adjustment.
