AIM Sports Ergonomic Vertical Rifle Grip w/ 6" Rail Section

"really nice and makes my gun seem alot lighter if you are looking for a grip buy this one it is amazing

"Awesome grip. I was looking through a gun magazine and found this same grip. This is used on really guns. This grip is solid, really solid plastic and there is a small hole through the middle so its light. It comes with a metal rail that can attach to any M4 or M16 grip. Plus it's cheap. Get it, your accuracy will increase, your gun will feel lighter, your gun will look cooler, and it won't burn a whole into your wallet. This is one of the best things your can buy for your gun.

"Love this ergonomic forward assist grip. Its slim, light and reliable.

"Really good grip. Evike's pictures make it look like pure, polymer suffering, but I bought it on its functional merits, and it's much better than the picture had me thinking.

Pros:
-Ergonomic style, with contours that aren't so deep as to cause excessive strain.
-Long, so you can get a good grip and solid leverage. Fantastic for shotgun pumps.
-Comfortable polymer, has that nice cushiony feel while still being solid construction.

Cons:
-Long rail space needed. Not an issue for me at all.
-Feels awkward on CQC specialized rifles, due to how you'll be holding the grip.
-Isn't super amazing aesthetics.

Overall, a good grip. A little much for CQC specialized rifles, but for medium and longer , it's a really nice feeling grip. Does its job well.
