Hilton,

While at GTC recently, I fired a neat little Colt M4 with an Aimpoint mounted just forward of the rear sight pedestal. The remainder of the carrying handle had been milled away to the upper receiver and replaced with a weaver mount.
The placement of the optical axis was such that the red dot could be seen thru the rear peep and sat right atop the front post, as an ideal sight picture. Is this the set-up to which you refer, and if so, would you recommend this modification for the Colt 9mm Carbine?
