width of the risers 140 should be at most as wide as the rail of the low rail sight the height of each riser 140 can be such to that the rail 135 is level with the barrel 120 once installed that is if the low rail sight is sloped toward the front of the barrel 120 the risers 140 can increase in height toward the front of the barrel 120 to level the slope the riser 140 that will be nearest the buttstock 110 can be made into an elongated and tapered end 145 piece the tapered end 145 can provide additional stability to the high rail sight extension 130 and provide a visual gradient from the barrel 120 to the top of the rail 135 further the top surface of the tapered end 145 can continue the scalloping pattern of the rail 135 for additional glare reduction in another contemplated embodiment weighting elements can be added to the risers 140 to compensate for differences in barrel 120 weights to promote design unity the exterior surfaces of the risers 140 including the tapered end 145 can be worked to mirror any patterns already present on the risers of the low rail sight further.
