This kit allows installation of a QD socket to first generation LMT SOPMOD stocks. Kit includes an 18-8 stainless steel QD socket, 8-32x3/4" flat head cap screw, and 8-32 threaded binding screw.All credit for this combination of parts goes to Jason Trusty at Gear Sector. The kits have not been available for some time, so we have pieced them together and are offering them at a similar price.These QD kits may or may not fit B5 SOPMOD stocks that lack a built in QD socket, as their hole sizing is not consistent. Weight: 0.3 ozMade in the USA. Requires a 3/32" Allen wrench for installation.
