I recently attached an AR-style carry handle to the accessory rail on top of my receiver (500A Cruiser, 18.5" barrel). The carry handle has adjustable iron sights on it, but I'm wondering what front sight to get to replace the factory front bead?? My concern exists because I have an ATI Halo saddle on top of the receiver; the picatinny rail sits on top of the Halo saddle; the carry handle sits on top of the picatinny rail. The front sight will need to be tall enough to clear all that, and I don't know enough about front sights to determine the best course of action. Thanks in advance!!
