Description
The TacFire Gen 3 handstop is built to give you a repeatable grip reference every time you bring your rifle up. Instead of wondering where your support hand lands on the rail, you get a clean aluminum stop that keeps things consistent from shot to shot. It's the kind of thing that sounds small until you're running drills and realize your hand position isn't drifting anymore.
2-Slot Design Works with Your Rifle
The two-slot configuration uses M-LOK attachment points, which means it fits on any modern M-LOK rail system without eating up excessive handguard space. That's important if you've already got a light, laser, or other gear mounted up front. The compact footprint lets you keep everything else in place while still getting the benefits of a solid handstop. It's also low-profile enough that it won't interfere with shooting techniques or transition between positions.
Aluminum Construction That Stays Put
Machined from aluminum and finished in black, this handstop is built to handle real use without adding unnecessary weight. The material is durable enough for regular range days and field work, while staying light enough that you won't notice it's there. Every TacFire accessory comes with necessary mounting hardware, so you can get it installed without hunting for extra parts.
Simple Function, Real Value
This Gen 3 handstop does one job well: giving your support hand a consistent stopping point. That means your grip stays locked in during transitions, target changes, and sustained shooting. Hand placement consistency is one of those foundational elements that improves control and accuracy over time. Whether you're working on speed drills, precision shots, or just running through standard practice routines, knowing exactly where your hand goes makes everything more repeatable.

Frequently Asked Questions
Will the TacFire MAR133G3 fit on my handguard?
Yes, if your handguard has M-LOK slots. This 2-slot handstop is designed to mount on any standard M-LOK rail system. It's compact enough that it doesn't require a large handguard section to work effectively, though most setups benefit from having at least 7 inches of rail space available for comfortable hand placement.
What's the benefit of using a handstop instead of a full foregrip?
Handstops take up less rail space than vertical grips, making them ideal if you're running lights, lasers, or other accessories. They provide the same hand placement reference point but with a lower profile that doesn't restrict your hand position to a single grip style. You get consistency without sacrificing flexibility.
Does this handstop come with everything needed for installation?
Yes, all TacFire accessories include the necessary mounting hardware. You'll have everything needed to secure it to your M-LOK rail. A simple hex tool is usually all you need to tighten it down, though hardware specifications can vary so checking specifics before installation is always smart.
Is the Gen 3 different from earlier handstop versions?
The Gen 3 incorporates improvements and user feedback from earlier generations. While the core function remains the same—giving you a solid reference point for hand placement—the refinements in the Gen 3 design result in better overall usability and a more optimized experience during actual shooting.
