I have a serialized Polymer80 frame that I want to build a 17 or 34 from. I was looking at the ZEV slides (the ones with no holes) and one of the features I really liked is that the RMR cut is so deep that you can co-witness with regular height sights.

I also looked at the Brownells slides and they mention:

Includes patented optic cut technology pioneered by ZEV Technologies. Patent No. RE47335

So do the Brownells slides work the same way? They would definitely be cheaper even though they could have bothered ramming in a channel liner like everyone else.
