I own a State Arms Shorty. It utilizes the same action/bolt you have.
Mine, is highly modified for Benchrest Matches in the FCSA
Mod's are
Action bedded in Manners Carbon Fiber Stock
34" Feddersen Barrel with Armalite AR-50 Brake (much better than the SA it originally had)
Front & Rear Slides made for Rests used in match.
If I knew how to post a picture here I would. If you want to see it, PM me and I can send them to you direct.
Lastly, the gun shoots far better than my abilities. It shot a .6 MOA 6-7/16" and a .2 MOA 2-5/8" ( 2.438" )5 shot groups at the FCSA WC this year in Raton, NM
