Daniel Defense Improved Vertical Foregrip - Black

This grip is the cheaply made and has no place on my rifle. The grip doesn't have an attachment to secure it in place. It is held in place by the plastic storage tube that slides into the grip and has two protruding buttons for lack of a better term to hold pressure against the picatinny rail. The screw in storage cap is what holds the pressure and keeps the grip from moving. So when the cap is taken off or lose the grip will slide around. I was truly disappointed in the quality of this grip and I plan to return it.

Solid vert grip. Better quality than Magpul, also quicker and easier to adjust with no tools needed. Designed​ similar to the KAC mil spec vertical grips.

Not really impressed with these, I bought a couple of them because they had the storage compartments and figured it would be nice to have batteries on rifles that dont have storage in the pistol grip or stock.

<br>They only fit on half the pic rails I tried them on, and I can only fit a single CR123a in the compartment. 2 CR123a's wont fit nor will a single 18650 which is what I really wanted them for. I will say that what rails they do fit, they are very solid on with no wobble.

<br>The KAC, Magpul, and GG&G foregrips I own all fit on the other rails this one wouldn't so IMO the issue is with this grip not the rails.
