Ar15 carry handle weaver mount with extended rail - NcSTAR AR15 Carry Handle Mount - Z Type

My first AR15 upper - as a civilian - was an A2 with the fixed carry handle. It made any kind of optics a challenge: the fixed handle sits up higher than the detachable version, and the detachable puts your scope up 2” (app.) high, as it is. But this upper is an original DoubleStar chrome-lined, CHFB, so it was worth working with it.
This NcStar mount fits snugly in the sight groove of the handle and bolts down firmly like an anchored ship. The extension, in addition to lowering the rail that runs level over the barrel, compensates for the kind of riser you likely have on your red dot optic by lining it up with the standard height front sight. I get a great co-witness from my Vortex Sparc on it’s riser, and if you’ve got a Sparc you know how many mounts say “will not co-witness with Vortex Sparc”. If you DON’T have a Sparc, that maybe your reason.
It not only holds a firm zero, the way it fits squares off the front curvature of the carry handle giving it smart looking OEM look and less of an aftermarket/retro look.
A nice-looking, co-witnessing mount that still allows a scope to be effectively mounted on the handle for $15.00?
There may be more expensive solutions, but you won’t find a better one.
