I have a light with 1" tube I'm wanting to put on the railed gas block of my 450 Bushmaster upper. The light came with a mount but it doesn't have enough of a rise to allow the light to clear the hand guard and barrel. I have found a couple scope rings with a rise, but they are over $100. I know cheap isn't good, but I don't need to spend that much on the mount. Does anyone know of a cheaper option. Thanks.
