Looking for cheap, carry-handle mount scope

[xrMike]

I normally shoot with irons, but am thinking about picking up a cheap, carry-handle mounted scope to use for load development purposes. I figure that putting glass on my AR when I'm shooting for groups -- using different amounts of powder, bullet seating depths, etc. -- will eliminate my eyesight as a variable, and therefore give me more accurate, representative groups.

I've been able to shoot .75 MOA (10 round) groups with irons on my best days. I'm pretty sure my WOA upper and my reloads are capable of better than that, but the limiting factor is my eyes.

It has to be a carry-handle mount. As far as magnification, I'd only be using it for 100 to 200 yard bullseye shooting, but it'd be nice if it could still be useful out to 300 or more.

I found this one here:

and this page, with several choices on it:

I realize all of these are cheap, but would one of them MAYBE suit my purposes better than the others? I know nothing about scopes. Thanks.

I have several compact scopes on my carry handle AR's including this one:

as well as a couple of the 3x and 4x Colt copies such as the one you posted a link to. They are simple and reliable; they all hold their zero and perform as designed.

The concern with cheap Chinese scopes is whether they work and hold zero. Some work fine for a long time, some start having problems after a little use, some are bad right out of the box.

You'll find a lot of people with all these experiences. My problem is when they start drifting, it might take a while to figure out it's the scope if it's not a serious failure. I spent a good bit of ammo chasing a drifting zero on a Chinese scope once, and it was frustrating. It was replaced under warranty, but my trust isn't great any more.

I don't know what your budget is, but I'm fond of inexpensive Leupolds and Weavers. They're not as cheap as the Chinese scopes, but are good quality.
