Needs more description. - Aimtech Scope Mount For Remington 870 20 Gauge ASM220

This item is nice as it gives you that Red dot capability. However it doesn't tell you it's for a 12 gauge and you get two shims that work but make the process and little more complicated. It works so I'm giving it a 4 stars with 1 missing for the description. It is sturdy and I feel if I dropped it things wouldn't get bent out of shape.
