I found this set up very interesting and when tearing one of these frames down it gave me the idea for the Pneu-cocker frame. I had the idea in my head and was planning building one from scratch one day from a standard cocker, but then realilzed this was already done for me with much less modifications!!!

This marker come stock with removable feedneck, nice anno, metal shroud with rails, break beam eyes, and a DVD!! lol.
