Sturdy, easy to install, solid - Leapers UTG D Vertival Front Grip w/ Innovative Quick Release Deployable Bipod

Haven't shot with it yet, but it went on the quad rail easy, feels solid, and the bipod pops out easy with a quick squeeze of the support hand (release button is near the bottom on the left side of the grip). This is a tall/long/large grip, but that's so it can hold the recessed bipod, and raise the gun high enough to shoot with 30 rd mags once the bipod is deployed. The quick release is nice too (and feels sturdy, once tightened properly), as I have 1 other gun I can transfer this to (with another on the way). Swapping among the three will be a good test for this grip, once I make it to the range...
