Carteach is considering an AR carry handle scope mount
like the one shown above. The idea being the ability to temporarily tack on a scope during load development. Not a permanent set up... in fact it would probably go on/off right at the bench. Plunk it on, shoot groups for testing, and it comes off to go back into the range bag.I'm opening this up to Carteach readers. Thoughts? Have a better idea to share?

The biggest issue you will find is trying to get a good sight picture... If you go that way, get the lowest rings you can get to actually mount the scope. And you WILL have to re-zero anytime you take it on and off (at least that was my experience)...
NFO,
What I am considering won't even require zeroing the scope. I'm thinking of load development vs my aging eyesight.
At the bench, bolt on the mount with scope already attached, shoot for group size with various loads, and then remove the scope/mount.
I've had an AR with scope mounted to the carry handle before, and it made for poor shooting anywhere but the bench. That said, it sure helped decide between a 1" load and a 1/2" load.
I have one. It works pretty well. Use low mount rings and a scope with good eye relief. Until I got a new upper, I used it in that configuration, even in 3-gun.
If you set it on there tight, use lock-tite on the mating surfaces, and leave it mounted, it will hold zero. Taking it on and off is not something I did regularly.
I just did this with an H-BAR and wound up taking it back off. If you decide to do it, a cheek piece on the stock such as those used on the Delta H-BAR makes a big difference. They're cheap, too, so consider adding one to your rifle if you scope it. And as ASM said, that mount won't hold it's zero when removed and re-attached.
See if you can find one that offers the option of using your iron sights with the scope mounted.
Always good to have a backup to your optical set.

For what you're doing it should work great. No need to worry about zero since you're just shooting groups, and you actually want them away from the aiming point so you don't destroy it. No need for back up iron visibility. The cheekpiece idea is a good one. Consistant cheek weld will help you get consistent groups.
-I had a coffin handle scope mount way back before the Picatinny Rail became popular. I didn't like the high sights required, but it served the purpose. One caveat: alignment is through the bar on the bottom of the mount in contact with the groove on the coffin handle. The mount should NOT easily fit into the handle. Use super fine lapping compund down to jewelers rouge and marking dye to endure that you have the best possible contact between the three mating surfaces. That is the only way you will enure "repeatability" of zero when you take off & reinstall the mount. If the mount just drops in when you get it, it is too loose. Either return it for a wider one or figure out some method of shimming.
-I hate to be "anonymous" but I don't have any of the ID methods you use.

I have one of these... ARMS makes excellent products. This might fit your need, although it is a little pricey!
