Originally I was planning to go with a kx3 tucked under this rail on my pistol build. Things happened (NFA trust) and the pistol turned into a SBR. Now I want something smaller to allow me to run a suppressor.

I have a brand new 12" rainier force, never used, just hand tightened for pics. Would like to trade for something in the 9-10" range. Ideally would like a 9" force, but I'll entertain all offers.
