I am a old school traditionalist but that is a pretty clean application of new school on old school .
I myself am about ten years past much of any use of standard lever gun irons but have been reasonably effective with aperture sights.
I don't really hunt so we are talking range work when the light is fairly bright . Not real sure the apeature sights would work at dawn and dusk with my eyes .
One has to pick his battles as one gets older
The one thing that makes me bonkers is when I see some older fellow decide it is time to scope his lever gun and he somehow ends up with one of those "see thru" scope mounts that puts the center of the scope about 4" above the barrel . the idea is supposed to be that you can see the scope or you can peek under it and see the factory irons . The reality is neither the irons or the scope is more than 20% useable and the whole rifle is top heavy and clumsy as all get out
