I don't believe you will find any scope base that will let you remove just the scope and still use the iron sights with the bases in place. The OEM rear sight extends to about .2" of the forward most screw hole for the front base, then you have the step elevator which will extend back even further to cover that screw hole or interfere with any base that would be mounted there. So I doubt you could have a scope base and the iron sights on at the same time.

Even if you used a replacement rear like a Williams folding leaf, with the profile of the barrel you need a tall front base to end up level with the base on the receiver so it would block the rear sight anyway. Even on the Talley one piece you'll see that the front part is much thicker top to bottom to meet the barrel.

Looks like you'll have to just pick one or the other and dismount the scope completely if you want to use the irons.



Gunnery, gunnery, gunnery.
Hit the target, all else is twaddle!
