    I just picked up a 3x32 compact scope I plan on running on my AR style (stock is buffer tube in line with bore) PPC. Big selling point was being lightweight, so I don't want or need any super sturdy one piece mount, thinking about just some lightweight rings. What ring height works well on an AR, extra high?

    Will your scope mount properly with separate rings or will you need a cantilevered mount? What is the tube diameter?

    It's one inch and compact, so some one piece mounts will not work. Rings should work fine.

    Was in Academy a couple of days ago and they had this on clearance for $67. I don't care that the BDC is for 223, it's only a couple of unlabeled hash marks. I've already worked out the ranges they represent for the calibers I want to shoot. Pretty good reviews from people paying more than twice what I did. :)

    I'd probably just order some Warne QD rings in various heights and return the ones that don't work. Unless youmcan google fu and answer off some website. Or maybe call DNZ. They are fairly local and may have a good answer for you.

    I don't want to over think this. I'm sure someone here has mounted a scope on an AR with rings. Just wondering if I should get high, extra high, or if I'll need a riser. Hmm, there's a joke in that last sentence somewhere.

    Aero ultralight is one piece and weighs like 3oz. I mounted the scope on my 3 gun rifle with one. Pricey but I like it.

    From arfcom:

    The geometry of the rifle is designed for iron sights that are 1.4" above the rail. To get that same elevation for a scope, you'd need "ultra high" mounts, or whatever they're called by the respective manufacturer designed to give the same 1.4" elevation. Leupold calls them "Ultra High". With that height, your cheek weld etc on the rifle, with the scope would be the same as with the iron sights. Lower rings might work just fine depending on your stature, how you hold the rifle, etc. I'm average height, and the 1.4" rings are perfect for me. I've had acquaintences choose the lower ring height that seemed to be perfect, find on the range with hearing protection, that the ear muffs interfered with the stock.

    I'm afraid most one piece mounts will not work with this short of a tube.

    you'll need at least 1.35" to 1.5" for standard AR15 ring height

    Pineoak is right. AR15 iron sight height over bore is 1.41", so if your scope's center line is lower than that on an AR that has a fixed A-frame front sight base/gas block, you'll have half the field of view occluded by front sight. If you don't have a front sight in the way, you'll still have a seriously low "tilt your face to the side and smash your cheek into the stock" cheek weld.

    Let me add a perspective I haven't seen yet. The interface between optic and firearm is so critical. SO critical. Wonky mounts cause more "mystery" accuracy illnesses with scoped rifles than anything else in my experience. You are already saving weight, but adding some measure of risk, by choosing individual rings rather than a one-piece mount. There is more complexity, more to go wrong with alignment and stresses and such. My advice is, you've bought yourself some room with weight by choosing light weight parts elsewhere. Choose your rings based on strength rather than weight. The weight difference is honestly negligible, an ounce or two here or there, that's it. Your arms and shoulders won't notice. But the pain in the ass you will save by having rings that actually hold zero over the long term is so much more important.

    I really like Glen Seekin's rings. His stuff is beautifully machined, carefully matched, always consistent. You drop his rings onto a spec 1913 MIL STD rail and there is no "slop" movement back and forth. They click in like LEGO pieces before you even tighten them on. Although they ARE in fact machined for lightness, I recommend them for their strength and consistent performance.
