This torque-sensitive rear sight widens the distance between sights for encouraging a steadier, more accurate hold. Magnum-sized rear aperture for a panoramic field of view. Solid, .187"-thick aluminum frame. Hard anodized with a shadow-black finish.
i replaced my peep sight with this,and found it to be excellent.it takes some time to adjust but well worth it in the end. stays in place like it should.
