I found an adjustable cheek piece that fits on a rifle buffer tube. MDT makes a carbine skeleton stock. It looks like a pretty cool stock, but I'm just screwing together a lightweight model 7 & didn't want to put another $250 in it. I called and ordered the cheek piece for this stock and for $50 it was delivered in a few days. It fits on an Ace arfx as far forward as you wanna push it. This is pretty cool for a chassis rifle that takes an AR buffer tube. You can use a lightweight stock and still have a nice place for your ugly face.
