FREQUENTLY ASKED QUESTIONS

B.O.S. Lock (Biometric Optimized Safety Lock) is a device designed to enhance firearm safety, particularly in homes with children. It functions by securing the slide of a firearm, preventing it from being fired accidentally. This biometrically controlled slide lock attaches to your existing handgun and gives authorized users access in < 0.5 seconds, automatically chambering the first round for you. Unlike other methods of firearm safety, B.O.S. Lock does not require you to compromise speed, mobility, or ease of concealment, providing peace of mind while keeping your firearms secure in your home.

Locking: When engaged, B.O.S. Lock's high tensile arm keeps the slide locked to the rear position, which accomplishes two things: Empty Chamber: The chamber remains open, ensuring no ammunition is present. This allows for easy visual confirmation. Disabled Firing Pin: The slide position prevents the firing pin from coming in contact with the ammunition, rendering the firearm inoperable while locked. Unlocking: B.O.S. Lock utilizes fingerprint recognition to grant access only to authorized users. It can store up to 50 fingerprints for multiple users. When the fingerprint is authorized, the arm releases the slide. Loading: Once unlocked, the slide automatically moves forward during the unlocking process, chambering a round if a loaded magazine is inserted.

This feature is particularly useful in applications where speed and user convenience are critical, such as security devices.

FPC 360Touch® refers to a technology used in biometric systems that allows fingerprint recognition from any angle, enhancing user convenience and security. This feature enables the biometric system to read and recognize a fingerprint regardless of how the finger is placed on the sensor, ensuring reliable and quick access.

FRR stands for False Rejection Rate. It measures the likelihood that a biometric security system will incorrectly reject an access attempt by an authorized user. In other words, it's the rate at which the system fails to recognize a legitimate user's biometric input, like a fingerprint, even though it should have been accepted. The B.O.S. Lock has a False Rejection Rate (FRR) of 1.4%. If there is a failed read, the system is designed to re-read in less than 50 milliseconds, ensuring quick and reliable access.

It measures the likelihood that a biometric security system will incorrectly accept an access attempt by an unauthorized user. B.O.S. Lock has an exceptionally low False Acceptance Rate (FAR) of 1 in 500,000 per read. This means that out of 500,000 reads, only one might be incorrectly accepted, ensuring a high level of security against unauthorized access.

CNC machined 174ph9 stainless steel refers to a type of stainless steel known as 17-4 PH, which has been shaped and detailed using CNC (Computer Numerical Control) machining. This process involves precise, computer-controlled tools that carve and shape the steel into specific designs. The "174ph" indicates the steel's classification, with "PH" standing for "precipitation hardening," a process that increases the material's strength and durability.

6061-T6 aluminum is a type of aluminum alloy that is known for its versatility and strength. The "6061" denotes the alloy composition, while "T6" indicates that the material has been treated through a process called tempering, which involves solution heat treatment and artificial aging. This treatment enhances the material's structural strength and resistance to corrosion.
