Mounted an old 4X weaver to my MP15-22, used redfield 1" high rings. I need the scope to be about 1/4" higher. Anyone know of any accessory to raise the scope or do I need to look for a different type of mounting system? Thanks.
Use a picatinny riser. Pretty common item. They even have them at amazon.com
They come in various hights and lengths. So just get whatever length that both rings will sit on and 1/4 inch or more rise.
