These go for about $5 on Ali Express. But then for the 30 bucks extra (plus shipping too...) you get the nice Vortex logo on it. Of course that makes it much better than the (same) chinese no name.
I never knew how valuable a scope level was until I started shooting LRT out to 1000 yards with my 6.5 Creedmoor,I have a few rail levels now for my airguns and I like them also,put one on my 500 Royale and my Texan .45 and HMx .357 will both get picatinny rail levels."rrdstarr"If you shoot more then 50 yds a bubble level is necessary.
