Rock solid MP5K/SP89 folding stocks made by Choate.  Choate builds these same stocks for HK Germany who sells them to militaries and police around the world.  These are high quality military grade folders!  Each folding stock comes new in wrap and counts as one US made part.  For those with post 89 rifles and U.S. part counts this is a big plus!  These stocks will fit the MP5K, SP89 and other MP5K clones that attach the buttstock via two push pins.
