A Small Addition To Your AR For A More Positive Handling & Improved Weapon Control

The AT3 AR-15 M-LOK Handstop is a lightweight and low-profile addition to M-LOK handguards that serves as a quick reference point to improve weapon handling and control. It is designed to work with the thumb-over method that adds a layer of confidence when handling your weapon to keep up your speed and accuracy when shooting.

Organic & Low Profile Design

This M-LOK Handstop offers an organic design that allows the shooter to easily manipulate the rifle in ways that are not quite possible with the other vertical grip designs. The curved side offers solid support for pulling your AR to your shoulder, while the flat side acts as a hand stop and place to brace the rifle against a wall, rock, or window frame.

The hand stop can accommodate a shooter’s preference with ease and only uses one M-LOK slot on an M-LOK rail system, leaving plenty of space for other accessories. Plus, these foregrips come in a wide variety of Cerakote finishes to complete a custom build and look for your AR-15.
