Does the qd attachment work on both sides? Some stocks I've read about the qd doesn't stay attached on the outside (for right handed shooters). Expert Answer

will a 18650 battery fit? they are the same length as two cr123s but slightly larger diameter. Expert Answer

Magpul states their STR Mil-Spec Carbine Stock will accommodate up to two (2) CR123A lithium or AA batteries. I would recommend contacting Magpul directly regarding compatibility with other batteries.

Helpful Positive Review This is my go to carbine stock by Taco-lover, Verified Owner, February 24, 2022
