Here is my review of the BW KK, I have been involved in the beta versions of these for a long time. They are awsome, While the video review is only on the basic features the dmr / sniper mode works very well. I would also recommend it for all DMRs, its only shortcoming is if you do not hardwire it in and inly use the plug and play option. It is a perfectly "suitable fet" this is coming from someone with a lot of years of experience dealing with computerized mosfets
