The M4 attachment is a quick attach-detach connector that will work left handed or right handed. It has been designed to be very quiet yet quick to install and remove. The connector is shown attached for right handed use and is available in two sizes, 1 1/4″ and 1 1/2″.

Just pull the strong steel buckle through the stock slot with the tab. The buckle then rotates so that it cannot go back unless turned by hand. The tab can then be laced through the buckle to quiet the connection. This takes about as long as it does to connect a conventional hunting type QD swivel.

The steel buckle is about .035″ too wide for the slot in Magpul (TM) stocks. A few seconds work with an ordinary file to remove less than a sixteenth of an inch from the top of the vertical rear slot corrects this problem. 1 1/2″ M4 kit slings can then be used with these stocks. The attachment goes in the ejection port side of the stock for right handed use just like it does for the standard M4 stock. When it is connected this way you can switch aim from strong side to weak side without passing the sling over your weak side arm. Just loosen any of our 2P models with the quick adjust feature and you’ll have no problems with strangulation by sling! Hangs better and closer to your body too.
