Description
The UTG Leapers Model 4 vertical foregrip gives you a firmer, more natural hold on your rifle without locking you into one position. It swings through five detented angles and clicks into a reinforced lockup, so whether you like a straight vertical hand or a forward-canted grip, you can set it where your wrist feels best and fold it flat when you want to slim down the profile for storage or transport.
What Sets This UTG Folding Foregrip Apart
The finger grooves are shaped to fill your hand and keep things from sliding around under recoil, and the whole thing is molded from impact-resistant polymer that shrugs off knocks. The mounting deck slides straight onto a standard 1913 Picatinny or Weaver rail and clamps down with a screw, so once it's snugged up it stays put. At 6.9 ounces and about 5.6 inches tall, it adds real control without weighing down the front end of your build.
Ambidextrous Panels and Hidden Storage on the Model 4 Grip
The removable side slide panels are a genuinely handy touch. Pop one off and you've got a spot to route a pressure switch for a light or laser, and since the panels work on either side, lefties and righties get the same setup. The end cap unscrews to reveal an internal compartment tucked inside the grip core, which is a good place to stash a spare battery, a bore snag, or small parts you don't want rattling loose in your bag.
This grip has earned a solid following among AR-15 and M4 owners who want a no-drama upgrade, and folks have mounted it on everything from carbines to shotguns with a rail section up front. Leapers backs it with their lifetime warranty, which says a lot about how they expect it to hold up. For anyone building out a rail and looking to improve handling and muzzle control, it's a dependable pick that punches above its weight.

Frequently Asked Questions
What rails does the UTG folding foregrip mount to?
The mounting deck slides onto standard 1913 Picatinny and Weaver rails, then clamps down tight with a screw. That covers most AR-15 and M4 handguards along with plenty of shotguns and other platforms that have a rail section up front. If your handguard is a smooth plastic heat shield with no rail, it won't attach.
How does the 5-position folding feature work?
Press the position button to swing the grip forward or backward, then release it to lock into one of five angles with a reinforced lockup. You can set it straight vertical, cant it forward, or fold it flat against the rail to slim things down for storage or transport. It's quick to adjust in the field once you find the angle your wrist likes.
Can I mount a light or laser pressure switch on this grip?
Yes. The side slide panels pop off so you can route a pressure switch underneath, and because they work on either side, it's a clean setup for left and right-handed users alike. It keeps your switch protected and within easy thumb reach.
What can I store inside the foregrip?
The end cap unscrews to reveal an internal compartment inside the grip core. It's sized for a spare battery like an AA or lithium cell, but people also use it for small parts, a bore snag, or anything they'd rather not lose in a range bag.
