I have a skeleton stock on a number of my 1022s. All my chassis are either PMACAs or Fort Arms Arrowheads. The rear stocks were purchased on the bay. They are basically AR buffer tubes (A2) with a fixed metal and rubber recoil pad, castle nut and sling mount. Very sturdy, comfortable and even more minimalist than MFTs stock. It adds a a great lop and best of all no bulky look.
