We have a good relationship with Will at red jacket and he built some 8inch ZKM AK rifles for us.
W love the guns but thought we would show what we do to make them more usable in my opinion so hear you go.
We cut down an ultymack rail and fit it to the gun cut the front sight hood do action work safety work mount an aim-point and just go thru the gun for any other thing the customer my need.
We had custom bags made for all of them so we can have a nice counseled long gun with us most the time.
We cut and shape the one that is on the gun when it is built.
I have found out that if you have big hands or glove some of the aftermarket safeties are too easy to engage accidently.
So in the long run we just cut heat bend shape refinish and tune the factory one.
Thank you for the ?.
