MagnetoSpeed — yes, the manufacturer of the eponymous gun-mounted chronograph — has just released a very spiffy AR grip called the M-Series Grip System. Four different modules can be stored inside of the grip, clicking into place and ejecting under spring power somewhat like a pistol magazine…
Module 1 is a functional, 3-round magazine called the MiniMAG.
Alternatively, the MiniTORCH is a bright flashlight that can be ejected from the grip and used as a separate unit or clipped rapidly to a rail mount.
The DryBOX can be used to store small items that need water-tight containment.
Finally, the MiniPOD is a rear monopod that rapidly ejects to a 3″ length and then can be fine tuned with a thumb wheel.
TTAG has requested a review unit to borrow, but on paper I certainly dig the M-Series Grip System!
