What is the Byrna Mission 4? More Than Just a "Byrna Gun"

The Byrna Mission 4 is a shoulder-fired, CO2-powered launcher designed by Byrna Technologies Inc. While often colloquially referred to as a "byrna gun," it's crucial to understand its classification as a less-lethal device. It does not use gunpowder and is not legally considered a firearm in most jurisdictions, meaning it typically doesn't require the same permits or background checks associated with traditional guns (though laws vary by location, and responsible ownership is paramount). The Mission 4 is specifically engineered to fire .68 caliber projectiles, which can be chemical irritants (like pepper or tear gas formulations, such as Byrna MAX or Byrna Pepper projectiles) or hard kinetic projectiles for pain compliance. Its primary purpose is self-defense and home protection, offering a means to deter, disorient, and incapacitate a threat from a safe distance, thereby creating an opportunity to escape or call for help. It's a step up in terms of form factor and capacity from Byrna's pistol-style launchers like the Byrna SD, offering a more stable and rifle-like platform. The "Bundle" or "Kit" aspect means it usually comes with essential accessories to get started.

Design & Construction: AR-Style Ergonomics and Robust Build Quality

The Byrna Mission 4 boasts a design that is both familiar to those accustomed to AR-platform rifles and built for durability.

AR-15 Style Ergonomics

One of the first things users will notice is its AR-15 style stock, pistol grip, and safety selector. This design choice offers a familiar handling experience for many and provides a stable, comfortable platform for aiming and firing. The adjustable stock allows users of different sizes to achieve a proper fit. The ambidextrous safety and charging handle further enhance its user-friendliness for both right and left-handed operators.

Durable Magnesium Receiver and Construction

The receiver of the Mission 4 is often constructed from durable, lightweight magnesium, contributing to the launcher's overall robustness without making it overly heavy. Other components are typically made from high-strength polymers and metals, designed to withstand the rigors of use and provide long-term reliability. This solid build quality is essential for a device intended for home protection.

Picatinny and M-LOK Rails

For customization and accessory attachment, the Mission 4 is generously equipped with Picatinny rails on top and M-LOK slots on the handguard. This allows users to easily mount optics (red dot sights, scopes), lights, lasers, foregrips, or other tactical accessories to tailor the launcher to their specific needs and preferences. It also comes with flip-up adjustable sights as standard.

Performance & Projectiles: CO2 Power, Accuracy, and Non-Lethal Impact

The effectiveness of the Byrna Mission 4 as a less-lethal rifle hinges on its CO2-powered launching system and the types of projectiles it can fire.

CO2 Powered System

The Mission 4 is powered by standard 88g CO2 cartridges, which are housed within the stock or body of the launcher. A single 88g CO2 cartridge typically provides enough power for a significant number of shots (e.g., 30-40+ full-power shots, though this can vary with temperature and firing rate). The CO2 propels the .68 caliber projectiles at velocities often up to 300 feet per second (FPS).

Projectile Types and Their Effects

Byrna offers several types of .68 caliber projectiles, allowing users to choose based on their needs:

Byrna MAX / Byrna Pepper Projectiles: These are chemical irritant rounds containing a potent blend of OC (pepper spray) and CS (tear gas). Upon impact, they rupture and disperse a cloud of irritant powder, causing intense burning sensations in the eyes, nose, and respiratory system, leading to temporary incapacitation of an assailant.
Byrna Kinetic Projectiles: These are hard, solid polymer projectiles designed for pain compliance. They deliver a significant impact force that can deter an attacker through pain and blunt trauma without causing lethal injury.
Byrna Eco-Kinetic Projectiles: These are often biodegradable and designed for training or practice, offering a similar impact feel to the kinetic rounds but with an environmentally friendlier composition.

The ability to switch between projectile types adds to its versatility as a non-lethal gun for home protection.

Accuracy and Range

The Mission 4 is designed for effective engagement at typical self-defense distances, often cited up to 60 feet or more for accurate targeting. The rifle-like platform and sights contribute to better aiming and stability compared to pistol-style launchers.

The Mission 4 Bundle: What’s Included for Your Home Protection Needs?

The Byrna Mission 4 is typically sold as a "Bundle" or "Kit," providing users with a comprehensive package to get started with their home protection device. Contents usually include:

The Byrna Mission 4 Launcher itself.
Magazines: Often two 19-round coupled magazines (providing a total of 38 rounds ready).
CO2 Cartridges: Typically two Byrna-branded 88g CO2 cartridges.
Projectiles: A supply of practice/kinetic projectiles (e.g., 100 Byrna Kinetic Projectiles) and sometimes a separate tube of chemical irritant rounds.
A Byrna branded rifle bag or case for storage and transport.
Sometimes additional accessories like a cleaning squeegee or lubricant.

This comprehensive kit ensures users have the essentials to familiarize themselves with the launcher and be ready for a defensive scenario.

Byrna Mission 4 Review: Pros, Cons, Legality, and Is It the Best Non-Lethal Self Defense?

This Byrna Mission 4 review considers its overall effectiveness and suitability.

Pros:

Effective Less-Lethal Deterrent: Capable of incapacitating a threat from a distance with chemical irritant or kinetic rounds.
Rifle-Like Platform: Offers better stability, accuracy, and higher round capacity compared to pistol launchers.
No Firearms License Required (Most Jurisdictions): Generally classified as a CO2-powered launcher, not a firearm, making it accessible to more people (always check local laws). This addresses the "is byrna a gun" query.
Durable Construction: Magnesium receiver and robust build quality.
Highly Customizable: Picatinny and M-LOK rails for accessories.
Comprehensive Bundle: Kit includes launcher, magazines, CO2, and projectiles.
Relatively User-Friendly: Familiar AR-style ergonomics for many.

Cons:

Price: A significant investment, more expensive than many other non-lethal options or even some conventional firearms.
CO2 Dependency: Relies on CO2 cartridges, which need to be fresh for optimal performance and require replacement. Temperature can also affect CO2 pressure.
Projectile Limitations: While effective, less-lethal projectiles have range and impact limitations compared to lethal firearms. They are a deterrent and incapacitant, not a guaranteed fight-stopper in all scenarios.
Legality Varies: While not a firearm in most US states, specific regulations regarding pepper projectiles or launchers can vary by state and municipality. Responsible ownership includes understanding local laws.
Size and Storage: While more compact than some traditional rifles, it's still a rifle-sized device requiring appropriate storage.

Is It the Best Non-Lethal Self Defense Option?

For individuals seeking a powerful, rifle-style, less-lethal option with a significant deterrent factor and the ability to engage threats from a greater distance than a handgun-style launcher, the Byrna Mission 4 is a very strong contender for the best non-lethal self defense tool. Its robust build, high capacity, and projectile variety offer a compelling package. Byrna gun reviews for the Mission 4 are often positive regarding its effectiveness and build quality, distinguishing it from simpler byrna pistols or the Byrna SD.
