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 OPTIONAL ADD ON)
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

This is a fantastic stock but there is no hinge currently available for the Sig MCX platform. I had to cancel my order (sadly) and got the MCX skeletonized stock w/integral hinge that is the same stock that goes on the SIG MCX rifles.
