Description

The Arisaka Defense Finger Stop is a patent-pending, low-profile accessory designed for M-Lok rail systems. Unlike traditional hand stops, the Finger Stop features an ergonomically rounded profile, intended to be positioned between your index and middle fingers. This placement allows for a more forward position on the handguard, facilitating smooth transitions to kneeling or prone shooting positions without obstruction.

Beyond its primary function, the Finger Stop serves as a forward limit to prevent fingers from slipping off shorter handguards onto a hot barrel or suppressor. It can also be used as a barricade rest. Notably, according to the ATF, installing this accessory on a pistol's forward accessory rail does not reclassify the firearm under the NFA.

Constructed from CNC machined 6061-T651 aluminum, the Finger Stop is finished with a MIL-A-8625 Type III hard coat anodizing for enhanced durability. Installation requires a 5/32" Allen wrench (not included) and utilizes one M-Lok nut and one 10-24x5/8" hex cap head screw. Proudly made in the USA.

The ergonomic design of the Finger Stop is tailored to fit comfortably between your index and middle fingers. This positioning allows for a more natural hand placement on the handguard, which can improve control and stability when transitioning between different shooting positions. The rounded profile reduces hand fatigue during extended use, making it a practical choice for both tactical and recreational shooting.

Can the Arisaka Defense Finger Stop be used on any firearm with an M-Lok rail?

However, it's important to ensure that the rail system is correctly installed and that the Finger Stop is securely mounted to maintain its effectiveness and safety.

What materials are used in the construction of the Finger Stop, and why are they important?

The Finger Stop is constructed from CNC machined 6061-T651 aluminum, known for its strength and lightweight properties. This material choice ensures durability without adding significant weight to the firearm. The MIL-A-8625 Type III hard coat anodized finish enhances its resistance to wear and corrosion, making it suitable for use in various environmental conditions.

How does the Finger Stop affect the classification of a pistol under ATF regulations?

According to the ATF, installing the Finger Stop on a pistol's forward accessory rail does not reclassify the firearm under the National Firearms Act (NFA). This means that adding this accessory will not change the legal status of your pistol, allowing you to enhance your firearm's functionality without additional regulatory concerns.

What installation tools are required for the Arisaka Defense Finger Stop?

To install the Arisaka Defense Finger Stop, you will need a 5/32" Allen wrench, which is not included with the product. The installation process involves securing the Finger Stop using the provided M-Lok nut and 10-24x5/8" hex cap head screw. Ensure that the Finger Stop is tightly secured to prevent any movement during use, which could affect performance and safety.

In what scenarios is the Finger Stop particularly useful?

The Finger Stop is particularly useful in scenarios requiring rapid transitions and precise control. For instance, in tactical situations where quick movement between standing, kneeling, and prone positions is necessary, the Finger Stop provides a consistent reference point for hand placement. It also offers a secure grip when firing from behind cover or barricades, enhancing both speed and accuracy.

This lightweight design is ideal for maintaining maneuverability and balance, especially important during extended use or in dynamic shooting environments.

How does the Finger Stop contribute to firearm safety?

The Finger Stop enhances firearm safety by acting as a physical barrier to prevent fingers from slipping forward onto a hot barrel or suppressor. This is particularly important on shorter handguards where there is less space for hand placement. By providing a consistent point of reference, it helps maintain proper hand positioning, reducing the risk of burns or accidental discharges.

Is the Arisaka Defense Finger Stop suitable for competitive shooting?
