I have an ARMS #40A2 and a KAC 200-600 meter rear sight.
I would be willing to trade ONE of those two rear sights for a Gen2 RRA Dominator EOTech mount. (Gen2 has the A2 sight moved rearward to clear M4 handguards).
E-mail me directly at Slaughterhouse1@aol.com
I can get pics AFTER Christmas. (new Digital Camera under the tree
