The irons are the same as the Supernova tactical, much like a polymer version of LPA sights. The MR1 ships with both the same ghost ring aperture as the SN and a smaller aperture. The rifles are light, balanced and super reliable. Just don't buy one and expect to run it like an AR. Get an XCR, JRC/TD etc if you need non res ARness. Think of it more like an Italian Mini 14 that takes AR mags and shoots well.
