Shit like THIS clown is what pisses me off. He's talking about wrist over grip as 'the best grip' to use because of some competitive shooting bullshit, but its not practical to use because A- if you have armor on its hard as fuck to steady your rifle easily, B- you cant move through tight areas and round corners very well, and C- it tires you out. Military guys like magwell grip or vert grips close to the magwell because its easy and fast to bring your sight up for snap shots and lower it back down as you move around and transition. You will almost NEVER see an actual COMBAT rifle kitted with a fucking vert grip 15+ inches from the the damn receiver. its retarded and uncomfortable for anything but quick shooting drills.
fun thing to do. do a GIS for 'US ARMY IN IRAQ' and just look at all the combat troops holding their rifle the 'wrong' way according to THIS douche-canoe. Because Mr. 'i shoot gongs at 10 feet for 5 seconds' knows more about weapon usage than a bunch of combat infantry guys balls deep in bad guy country.
