I purchased this for my new G&G M4 CQB (Combat Machine Raider) set-up as my other fore grip is on my G&G M4 Carbine set up (Professional GR16 V.3) and my other one is MIA in my friends room. Anyways I pulled this out of the bag expecting the typical vertical grip but the material on it is sort of rubberized or whatever, when holding onto it with bare hands it feels comfortable yet grips well to the hand. With my Mechanix gloves I can maneuver my rifle in close quarters with ultra high precision all while in comfort and in style :D. Its more comfortable than my other vertical grips and the length is perfect. I highly recommend this grip to just about anyone.
Comfortable rubberized grip
Allows stability and precision aiming
Length is not too long
Allows going prone without worrying it hitting the ground (at least when I use my 20rd mags)
Battery compartment only holds one battery. Decent solution but my EOTech a common optic runs on two triple A's. No big deal really.
Might be too short for people with certain hands, guns, styles, etc.
