Arisaka Defense - Finger Stop for Picatinny Rail

The primary function of the Arisaka Defense Finger Stop is to provide a low-profile control point on 1913 Picatinny rails. It is designed to be positioned between your index and middle fingers, offering a forward limit to prevent your hand from slipping onto a hot barrel or suppressor. This makes it particularly useful in dynamic shooting scenarios where maintaining a consistent grip is crucial. Additionally, it can serve as a barricade rest, providing stability when shooting from cover.

The ergonomic design of the Finger Stop enhances shooting performance by allowing for a more natural and comfortable grip. Its slim profile fits seamlessly between the index and middle fingers, reducing hand fatigue during prolonged use. This design ensures that the shooter can maintain precise control over the firearm, especially when transitioning between shooting positions. The Finger Stop's placement helps in achieving a consistent hand position, which is vital for accuracy and speed.

The Arisaka Defense Finger Stop is constructed from CNC machined 6061-T651 aluminum. This material is chosen for its strength-to-weight ratio, providing durability without adding significant weight to the firearm. The Finger Stop also features a MIL-A-8625 Type III hard coat anodized finish, which enhances its resistance to wear and corrosion. These materials ensure that the Finger Stop can withstand harsh conditions and maintain its performance over time.

Installing the Arisaka Defense Finger Stop on a Picatinny rail is a straightforward process. It requires sliding the Finger Stop onto the rail and securing it in place using two nylon-tipped set screws. This secure attachment method ensures that the Finger Stop remains firmly in place during use, even under recoil. The precise fit to the 1913 Picatinny specification means that installation is quick and requires no special tools.

Yes, the Finger Stop can be used on firearms other than rifles, provided they have a 1913 Picatinny rail. This includes certain shotguns and pistols that are equipped with such rails. Importantly, according to the ATF, installing the Finger Stop on the forward accessory rail of a pistol does not reclassify the firearm as an 'any other weapon' under the NFA. This makes it a versatile accessory for various firearm platforms.

The Arisaka Defense Finger Stop is compact, measuring 0.75 inches in height, 0.3 inches in length, and 0.68 inches in width. It weighs just 0.4 ounces, making it an unobtrusive addition to your firearm. Its minimal size ensures that it does not interfere with other accessories or the overall handling of the firearm, while still providing the necessary functionality for control and safety.

The Finger Stop aids in transitioning between shooting positions by providing a stable reference point for the support hand. When moving from standing to kneeling or prone, the support hand often shifts towards the rear of the handguard. The Finger Stop's placement ensures that the hand remains in a consistent position, which is crucial for maintaining control and accuracy during these transitions. This feature is particularly beneficial in tactical or competitive shooting environments.

Yes, the Arisaka Defense Finger Stop is compliant with ATF regulations. Specifically, installing it on the forward accessory rail of a pistol does not result in the firearm being classified as an 'any other weapon' under the National Firearms Act. This compliance ensures that users can install the Finger Stop on their pistols without concern for additional regulatory burdens.

The MIL-A-8625 Type III hard coat anodized finish provides several benefits for the Finger Stop. This finish enhances the durability and longevity of the Finger Stop by providing a hard, wear-resistant surface that can withstand harsh environments. It also offers excellent corrosion resistance, which is essential for maintaining the accessory's integrity in various weather conditions. This finish ensures that the Finger Stop remains functional and aesthetically pleasing over time.

The Finger Stop contributes to firearm safety by preventing the support hand from slipping forward onto a hot barrel or suppressor. This is particularly important when using shorter handguards where the risk of accidental contact with the barrel is higher. By providing a physical barrier, the Finger Stop helps to avoid burns and ensures that the shooter maintains a safe and effective grip on the firearm at all times.
