Description
The ATI Forend Pistol Grip is one of those upgrades that punches well above its size. It bolts onto any standard Picatinny rail and gives your support hand a real place to plant, which pays off when you're driving the gun between targets or holding steady off a barricade. The grip is molded from DuPont glass-reinforced polymer, so it shrugs off heat, cold, and the kind of knocks that come with regular range time.
What sets this one apart from a plain fixed vertical grip is the folding, multi-position adjustment. A push of the button lets the grip swing and lock into different angles, so you can run it straight up like a traditional vertical grip or cant it forward into more of a hand-stop position. That flexibility makes it easy to dial in whatever feels natural for your build and shooting style, whether you're squared up on a two-way range or working a slow bench group.
Where the ATI Forend Pistol Grip Earns Its Keep
The textured surface is the quiet hero here. It gives your palm and fingers something to bite into so the gun doesn't squirm around under recoil or in sweaty, wet, or gloved hands. The ergonomic shape fills the hand comfortably without hot spots, and the ambidextrous design means lefties and righties both get the same solid purchase.
Fitting the FPG0100 to Your Setup
This grip is built for standard 1913 Picatinny and Weaver rails, which makes it a natural fit on AR-15, M4, and M16-pattern rifles, along with plenty of other rail-equipped rifles and carbines. Keep in mind the rail itself isn't included, so you'll want a section of rail on your handguard or forend to clamp to. Installation is straightforward with the built-in clamp, no gunsmithing required. It's made in the USA and backed by ATI's limited lifetime warranty, so it's a low-risk way to make a rail gun easier to hold onto.

Frequently Asked Questions
What does the ATI Forend Pistol Grip mount to?
It clamps onto a standard 1913 Picatinny or Weaver rail, so you'll need a rail section on your handguard or forend to attach it. The rail itself is not included with the grip. That makes it a good match for AR-15, M4, and M16-pattern rifles, along with other rail-equipped rifles and carbines.
Is the FPG0100 grip adjustable or fixed?
It's a folding, multi-position design rather than a fixed vertical grip. A push of the button lets it swing and lock into different angles so you can run it straight up or cant it forward toward a hand-stop position. That lets you fine-tune the angle to fit your build and shooting style.
What is the ATI forend pistol grip made of?
It's molded from DuPont glass-reinforced polymer, sometimes listed as glass-filled nylon. That material handles extreme temperatures and everyday abuse well, and the textured surface gives your hand solid grip in wet or gloved conditions. It's made in the USA and backed by ATI's limited lifetime warranty.
Do I need any tools to install the ATI Forend Pistol Grip?
No gunsmithing is required. The grip uses a built-in clamp that tightens down onto your rail, so basic installation is quick and hand-tool friendly. Just make sure it's snugged down securely against your rail so it stays put under recoil.
