This vertical grip is mostly used for when people want the grip fully in your hand, giving you the most wanted control. I use it on my custom Echo 1 Stag Arms M4 that I changed to a shorter barrel so I could have a comfortable control with such a short carbine, and it works wonders. In fact, I even lost one of the 2 screws and it still feels ultimately strong. Being it MagPul, the plastic is virtually indestructible with no value of comfort taken away to compensate. Fantastic grip and I endorse it to be bought for SMGs and Carbines.
-Sturdy (lost 1 screw and it still latches on with strength)
-Practically indestructible (It's the MagPul MagIc)
-Hollow in the middle (Pro for me, it's more comfortable)
-gives me the control I need for my weapon
-MagPul is always a pro
-Price I guess
-Everyone is going to see how it will be really short and stubby being a con, it was for me looking at it but when I bought it it changed my mind immediately
