It's a basic gas thru 'T' stock that I scored off EBay for $20. I removed the 'T' bar in the back (one hex bolt) and replaced it with a section of aluminum bar stock that I bent into shape. Its held up really well over the years and shifted the shoulder point to exactly where I wanted it. I used to use it on my phantom as well, and because it had a bottom line setup, I'd flip the stock over to raise the shoulder point.
