Essential component of a multi-use sling system - Magpul Type 1 Sling Mount Kit

These MagPul QD sockets provide a strong and low-profile attachment point for slings with QD swivels. They are not anti-rotational, so your sling will turn freely when attached. I would prefer they were anti-rotational, but it's not a big deal. I have installed these MagPul QD sling sockets on most of my long guns, which almost all have MagPul stocks. Used with parts MAG606, MAG529 (and other mid-gun QD mounts), and a MagPul MS4 sling, the user can set up most long guns for quickly switching between two-point and single-poing sling configurations. Most recently, I installed two of these sockets on a wood-stocked air rifle. Using a micrometer, I found the outer diameter of the non-knurled portion of these sockets to be almost exactly .500". I purchased a 1/2" Diablo Forstner bit, and with my stock securely clamped onto my drill press – I bored one hole near the tip of the forend and one hole near the center of the butt, both centered squarely on the left side of the stock. I then drilled 3/32" holes about 1" deeper through the center of those holes. I pressed the QD sockets into the stock using a vise, and I used the ~5/8" MagPul screws (after removing the threadlocker from the screws) to anchor the QD sockets in place. At the depth I bored the holes, the sockets protrude about 1/16" above the surface of the stock, which prevents the sling swivel from rubbing on the wood. The result is an excellent left-side mounted sling perfect for stabilizing my shots from various positions. I highly recommend installing MagPul QD slings on every long gun, and these sockets are typically essential for the job. It's a good product. Minus one star for not being anti-rotational.
