BHO in an AK is really just a gimmick IMHO because AK receivers don't have an activated bolt carrier catch like an AR or the Bren 2 but the Yugo mag does have the ability to activate a receiver mounted BHO. When you yank a BHO Yugo mag out of an AK the bolt assm slams shut. I dismiss the hybrid lower DH sells because it's just a huge step backwards for the Bren 2. It gives it all the features of an AK and removes the useful modern feature so......... just buy an AK instead.LOL! I was thinking, grind off the front and rear mag locking tabs (no need to "rock n lock" when you have a modern mag well) and cut in a mag catch notch on a poly Yugo mag.
