I'm looking for a side folding stock to add to my AK-74 build.  I'm talking about the one that folds to the left and is often seen on Krinks.  I believe ORF is using them on their SEAK II build.  I see that K-Var use to have them but are currently out of stock.  Who else might have them?

Also how are they installed?  Do I have to make modifications to the receiver like one has to do for an underfolder?  Once again I appreciate the help.
