Sorry...I'm being very confusing, talking about two scopes at the same time. The tac30 is almost the same scope as the mtac. The major difference is the illumination. Mtac has a dial, the tac30 you have to push a button. I THINK the magnification ring is different too. I have the MTAC on my 3 gun rifle but I also have one of the primary arms PA14X scopes on my 22.
I just posted the link to the tac30 as that is the lowest price I have seen on that scope for awhile. The usually run just shy of 300. The PA has always been around 120.
