So I have a Razor 5-20 and 35mm Razor rings. It sits too low so I purchased a raiser from gg&g but its too short. Who makes one thats long enough to space the rings far enough apart? Also my upper and Yankee Hill handguard don't have the 1913 rail spacing right. I was unable to line up the slots. I tried to put the rail 3/4 on the upper and partly on the hand guard but the slots wont line up correctly. This blows!
