Nice rifles and dog. I'd love to do a build like your shorty for future CQB and deer hunting. Don't think I'd go with the cheek riser though. Did you find it necessary? How's that AFG?
I found I needed the riser..it just made a good consistent cheek weld but to each their own. The AFG added a little more comfort to my wrist is all...again to each their own...I am still working on exaclty what I like with that shorty.
I want to use the shorty for hunting as well now and am going to put on a CASM Gen II on it and will need that riser as it will be the same set up as the full length.
