UPDATE: It looks like Magpul’s new MS3 is breaking cover in photo form in this photo of the STR stock. A drawing of the sling has been on their site, but here’s the first actual look at the new hardware they made for the sling.

The STR Carbine Stock is a drop-in replacement for M4type carbine stocks. The STR has improved cheek weld and two water resistant battery tubes on a reinforced polymer A-frame design.
