Product Details

We have designed this stock with the weight and compact size of PDW’s in mind. Coming in at 5.1oz the handling characteristics are phenomenal on shorter weapons. Weapons remain fully functional with access to controls with the stock folded and with Locking QD sockets on either side of the heel the U.L.S.S. is ready for your setup. Our stock is compatible with the familiar MCX folding hinge. Now including two M-LOK slots on top for future cheek riser compatibility! (HINGE NOT INCLUDED)

Product Features:

  • 1x PMM U.L.S.S. Stock in either Black or FDE 8625 type 3 class 2 industry standard hardcoat.
  • Lightweight at a mere 5.1oz (1.2oz lighter than a factory rattler stock).
  • QD mounts at either side of the heel.
  • Rubber butt pad absorbs recoil and keeps the stock planted in your shoulder.
  • Shorter length of pull to keep the setup compact.
  • Machined in house out of quality 6061-T6511.
  • 7.5″L/.59″W/3.75″T
