I got a weaver scope base that mounts to the carry handle. It's black and nearly mint condition. Its hollow so you can still use open sights with a scope mounted.
I listed it in Ebay before it occured to me to sell it here. But I figured someone here could get a good deal. If you win the bid mention you read it here at AR15.com and I'll throw in a couple of rounds of LC range brass once fired.
