Question about co witness and Aimpoint.

Hi everyone. So I saw SWFA has an M2 Aimpoint deal going on combo get the flash kill and mount with spacer.

I was wonder with the mount and spacer does this give a 1/3rd cowitness or a absolute co witness?

Would I be better spending 544 bucks on a Larue combo? If its a 1/3rd Id be interested in buying this.

Spend the money on the larue combo. You won't be sorry. The larue is 1/3 cowitness and just about bulletproof.

I was thinking that too, but the SWFA combo is pretty good price.

Price isn't everything. I am not saying that the other mount is bad, I honestly don't have any experience with them. but I know for a fact that larue are about as good as you can get. Oh and Bobro but they are a bit more than the larue.
