So, I have a 556 Classic with the rail-mount Diopter rear sight installed. It is an amazing shooter with iron sights, so I wanted to see what it would do with a scope. I bought a Primary Arms 1-6x with ACSS reticle. I'm looking for mounting options, preferably without removing the diopter. (Although, as I'm looking at it, I can't imagine how this could be accomplished without raising the scope waaaaaaay too high for a reasonable cheek weld.)

If I have to remove the diopter, I will, but wondering if others have discovered another solution??

I am using the American Defense Recon H for 30mm tube. The cheek riser is necessary to achieve a wield.

I had a scope on a low-mount and it worked fine. Scope is sub-optimal unless you get a flip down front sight though

Thanks guys. I will see what I have for rings, and test with and without the diopter sight.

Burris pepr.

I have a Vortex Strike Eagle with their mount. Nice set up nothing in the way of operations of the rifle. Chris

The true question remains..... What are you trying accomplish. Not here to rain on anyone's parade.

If the intent is to have a scope - mount the scope and remove the hard sights. In my years of instructing, competitions, and shooting, I've never had the thought of "dang, if I had my hard sights I could hit that target at 400yds".

One of the few places hard sights are useful is on a CQB rifle with a red dot. Then, we can open the can of worms with true co-witness or lower 1/3. Sidestepping this true life changing conundrum, folding sights will function best and keep the optic clear.

Configure the rifle how you intend to use it. Not for the hope of a zombie apocalypse or galloping hordes of invaders from far off lands. All these items are easily removable/replaceable with the simple turn of a driver.

Thanks for the suggestions.

As to the true purpose? I guess I don't have one. I got the 556 because I've always admired the 55X series rifles (which is why I chose the Classic), and getting one in the US relatively easily which also takes Stanag mags made it a no-brainer. Once I tried the trigger and shot it, I began wondering just how accurate it could be, taking a couple variables out (my eyesight and shooting positions), so, putting the glass on here is mostly a test to see what I do want to prioritize the rifle for. If it shoots bug-hole groups off the bench with a scope, it might permanently keep the scope and be used in our clubs military rifle match, for prairie dogs, and enjoyment at the range. If it does not, then I suppose the scope comes off and diopter goes back on and it's "just" a very nice modern battle rifle.

As you're going for accuracy, mount the scope low to get a proper cheek weld. Remove the diopter.

Your plan to revert to original condition is good if it doesn't perform.

Best of Luck.

Expect 2 to 3 inch groups at 100yds.

I'm already getting that with iron sights and my bifocal glasses... If it is that poor with the scope too, I'll definitely go back to the diopter.

This was my patrol swat. I had a 1x4 on it. Everything from 55grn to single loading 70, 75 grn bullets. It never got any better.

It was simply a battle capable rifle. Some would call that minute of man.

Just remove the diopter to scope as you wish. If you want versatility use QR scope mounts and keep the diopter handy.

Also wanted to mention that several of the models had receivers with a popsicle stick rear sight in the rail. They made quite a few sight and receiver changes w/o rhyme or reason, just look. If so equipped you have your back up ready.

You could also replace the front sight with a Samson or Midwest Industries front folding sight and a BUIS of same or different brand for the rear.

I have one of the Bushnell AR 3-9x in a Burris PEPR mount with a Samson folding front and a Troy folding rear.

Yep, mine has the popsicle stick folder. Mine is very difficult to access. My buddy's has a little tab which makes it easy to flip up...
