I am looking to get rid of the factory rear sight on my CZ to increase my sight radius (also, they're not great) and was wondering if others have had experience with Tech Sights or the Skinner Sight systems? I like the look of the Skinner sight but I have seen some really good reviews on the Tech sights. I am not willing to drill holes in the receiver or do any additional work; just want to plug and play, per se. Are there any other sight systems for CZs that exist out there that would be better than the two I have listed above? Ultimately, I would love to shoot long range with it.
