I'm looking hard at the Ultimak gas tube for my Saiga .223. After hours of research I've decided that's the best way to mount optics on an AK. Being able to co-witness the irons is a must for me. My end goal would be to pick up an Aimpoint H-1. I may try out a Primary Arms micro just to see if I like the idea of optics on my rifle. Anyways, do these things hold zero? Ever bump it hard or drop it? The beauty of the AK is that it is built like a tank. I'm not interested in mounting some flimsy, fragile crap on it. My next concern is cleaning. I don't go crazy on the gas tube but I do pop it off and scrub it out when cleaning. I'm assuming this is a no go once you mount the Ultimak? You would lose your zero right? So how do you folks address the cleaning issue? Any other thoughts or reviews are greatly appreciated. Wanna kill these ads? We can help!
