This is a really good afg - FAB Defense Rubberized M-LOK Compatible Ergonomic Pointing Grip Combo Pack

I realize AFGs and VFGs are a totally subjective thing, but this one works for me. I'd gone through several grips on my 16 inch AR and have finally found one I like. For me this one is GREAT. The mounting hardware is good (that's not always a given!) and the feel of the grip material is like that on a Magpul K2+ grip. The thumb tab feels great and doesn't add too much width to your gun in a bag. It takes a decent bit of rail space, but on a 16 inch gun that's a non-issue. On my 10.5 inch AR I have a Stryke Industries AFG and that works great on that gun. I tried that on my 16 inch gun and it didn't work for me there. What finally made things click for me was closing my eyes and pretending to hold my gun and then looking to see how my hands were positioned. The Stryke Industries has my palm parallel to the ground. That seems fine on the 10.5 inch, but when extended further out it's uncomfortable. This FAB Defense grip is angled just right and fits my normal sized hand perfectly.
