Nick Wantland: Years ago, the Marine Corps was looking at ways to deal with the ergonomic and length-of-pull issues they were having with the fixed stocks on their M16A4s. The fixed stock was designed long ago before the introduction of thick, modern body armor. Depending on the Marine’s body type, and what style optic they were using, the lack of adjustability in the stock length was causing tons of ergonomic, mobility, and eye relief issues.

To compensate for this, a lot of guys were having to hike the fixed stock way up on their shoulder. Basically until only the toe of the buttpad was resting high on the shoulder… “out of pocket”, as they say. This shooting stance causes lots of issues with accuracy, and with the mechanical functionality of the gun.

“Retain the reliability and beneficial characteristics of the full length rifle buffer system”

The Marines were looking for a way to retain the reliability and beneficial characteristics of the full length rifle buffer system on their 20” guns, but they wanted to be able to use an adjustable stock. Simply popping a standard carbine stock and buffer setup on there does not work. It leads to bolt bounce, erratic cycle timing, and lots of other issues.
