How well do the Russian Kochevnik-2 style mounts, such as Armacon Kochevnik and Circle 10 SOMAK, hold up to abuse? I'm looking to purchase a Draco Mini and would like to add a side folder and red dot or RMR. I'm considering the TWS Dogleg, AKARS for picatinny dust covers and the TWS Bitty Dot, Attero Bravo/RMR but I see these all have issues with losing zero. I have seen a couple of videos saying the Circle10 SOMAK is rock solid but I've seen videos for all the other options that say the same even though they have issues from time to time so I'm trying to find first hand, long term experience.

I'm looking at the Kochevnik-4 which is a low-rider version of the Kochevnik-2 and provides better co-witness and cheek-weld. I understand Russian Kochevnik-2 are very popular in Russia but have not seen any reviews from oversees (Europe/Russia, etc). There is probably a lot of information out there but I can't find anything.

TX-Zen might know, hopefully he'll chime in; he runs a site dedicated to russian optics and the like and has had plenty of time using them.
