I've been noticing that some load outs have an Anti-cant attachment to them to help combat the lean and I'm having some issues with trying to find one myself. I can't use one that attaches to the scope as I'm using a NcStar Gen III Mark III Tactical 3-9X40mm. I also don't like the ones that hang off far to the side (neon liquid doesn't hide that well). So I'm looking for a rail attachment Bubble Level that can sit under my scope. However the closest thing I can find is the Knight Armament Anti-Cant for $70. RAIL MOUNT ANTI-CANT DEVICE It seems like the price for something like that is a bit steep. Short of Macgyvering it, I was wondering if any of you have a suggestion for what I'm looking for?
