Accelerated Radial Spread / Instant Expansion Technology:

By harnessing the spin generated forces from a rifled barrel, a MI4 bullet can achieve a rapid radial expansion producing an optimal spread pattern up to four times faster (4x) than buckshot, resulting in a significant tactical advantage - particularly at close engagements.

Example: A MI4 round can achieve a 12 inch spread as quickly as 8 feet from the tip of the gun.


Collateral Damage:

Is damage aside from that which was intended. The unintentional damage or incidental damage affecting facilities, equipment, or personnel, occurring as a result of applying force or taking action, directed against targeted enemy. Such damage can occur to friendly, neutral, and even enemy forces.


Command and Control Aim Points (CCAP):

The term Command refers to the cognitive ability to think and reason (i.e. the brain) and the term Control refers to the arms and legs that offer mobility and or control of a weapon system. In short, removing the ability to think or react will prevent an enemy from posing any further threat.


C.Q.B engagement or Close quarters combat (CQC)

Are defined as a short-duration, high-intensity conflict, characterized by sudden violence at close range. This is the type of fighting where the enemy is engaged with personal weapons at very short range, potentially to the point of hand-to-hand combat.

In the typical CQB scenario, the attackers try a very fast, violent takeover of a vehicle or structure controlled by the defenders. Because enemies, hostages/civilians, and fellow operators can be closely intermingled, CQB demands a rapid assault and a precise application of lethal force. The operators need great proficiency with their weapons, but also the ability to make split-second decisions in order to avoid or limit friendly casualties.



The specific combination of the high mass bullet segments propelled at a high velocity with a low strength tether, that upon striking a live human or animal target is specifically designed to quickly break the tethers and allow for the maximum depth of travel of the segments (multiple wound channels) inside the body cavity.


Delivered Stopping Power:

Describes the actual amount of penetrating/damaging ballistic injury upon impact with a live human or animal target. Considerations include the location of impact and in the case of multi-projectile shot the number of wound channels created.


Double-tap firing sequence:

The intentional firing of two consecutive rounds at an intended target. A double tap is a shooting technique where two shots are fired from one gun at the same target with very little time in between shots.


Harassment fire:

Harassment fire™ is used to describe a smart stack configuration wherein every other or every third lethal round to be fired is a MI4 Stopper round. This phrase simply describes tactical advantage gained/preserved in a prolonged engagement involving one or multiple enemies. By blending in the high hit probability of MI4™ rounds to a shooter’s typical load sequence, he or she can engage multiple bad guys and not forfeit the high hit probability for each new target.


Hit probability:

The likeliness of hitting an intended target with a ballistic projectile, taking into consideration all contributing detrimental factors.


Last Second Twitch or LST:

Simply put, Last Second Twitch describes how the shooter’s final aim point when the bullet leaves the barrel of the gun is different from when he/she started pulling the trigger. As most shooters know, a bullet’s trajectory (and ultimate strike point) is primarily determined by the gun’s alignment at the time of firing. What most people do not realize is that high pressure situations magnify the body’s psychological (fear/anticipation) and physiological (shake/paralysis) reactions that naturally occur each time the trigger is pulled when firing a gun. The combined reactions more often than not result in marksmen's error, causing them to miss their intended targets.


One gun solution:

Provides the shooter the ability to quickly and accurately deliver varying levels of stopping power from a single weapon. One of the biggest threats to a person in a hostile situation is a delayed reaction from indecision. The introduction of our Smart-Stack doctrine of use provides the shooter a single weapon solution regardless of the threat level. Shooters no longer have to make a split second life or death choice as to what weapon to use (e.g. Pepper-spray, Taser or Primary Gun).


Orthogonal orientation:

Two vectors are orthogonal if they are perpendicular, i.e., they form a right angle. As it relates to ballistics, the spread pattern of our new bullets is confined substantially to a single plane of expansion at a right angle to the bullets trajectory path. Simply put as a result of the spin generated forces from the rifle barrel, the three segments of a MI4 projectile are first forced to move out from the center of rotation and then are gyroscopically held in orbit at a right angle and predetermined distance from the original center of rotation (flight path). This one feature not only assures a simultaneous impact of the segments on the target, it also preserves the precision and accuracy of a spin stabilized bullet.


Potential stopping power:

Describes in a best case scenario the maximum ability of a projectile to cause a penetrating/damaging ballistic injury upon impact with a live human or animal target.


Prior-to-impact expansion technology:

Describes a ballistic projectile that is designed to expand instantly as it leaves the tip of the gun. The rapid expansion of the projectiles increases the bullet’s area of influence (spread) prior to striking the intended target, thereby resulting in increased hit probability. This field of ballistics is subdivided into two categories: (i) infinite expansion and (ii) finite expansion. A traditional example of infinite expansion would be scattershot (i.e. “buck shot” or birdshot”). The new wide envelopment bullet is an example of a finite expansion bullet due to its interconnected spider web like tethers.



Is the ability to draw and shoot faster than ever when marksmen need a first hit advantage. This is possible because MI4 bullets compensate for most if not all of the typical aim point errors by expanding rapidly to achieve an optimal wide shot profile.


Rapid-stop technology:

The unique ability of our Multiple Impact Technology to mitigate the risk of over penetration, while allowing for the maximum amount of stopping power to be delivered to a live animal or human target. For example, when striking a live human or animal target, the Rapid-stop technology designed into each segment will allow each segment to re-orientate its heavy end first via a “weathervane” affect, thereby allowing each segment to achieve maximum penetration. However, when the segments strike a hard target, such as an interior wall of a home, the initial contact of the keyhole profile dissipates energy in the first layer of the wall; then, as the tethers momentarily cut into the sheet rock prior to braking, they dissipate more forward energy; next, the projectiles strike the second layer of sheet rock at a lower velocity, thereby dissipating further energy as they attempt to pass through at a slower rate.


Separation Distance:

The specific amount of space between the shooter and the intended target.


S.K.I.P- Stack: (Systematically Kill the Intended Person)

The combined and sequential use of a lethal (MI4 Stopper) round followed by a standard slug, then repeating the sequence for the remainder of the load. This unique blending of ammunitions creates not only a tremendous tactical advantage at the onset of an engagement, it preserves the high hit probability for each consecutive engagement thereafter. Creating a brand-new tactical advantage in a prolonged gun battle, an effect we call Harassment Fire. Harassment fire™ is a phrase that simply describes tactical advantage gained by incorporating the high hit probability of MI4™ rounds to improve shooters typical load sequence. NOTE: S.K.I.P-Stack doctrine is most effectively used with a “double-tap firing sequence”.



The combined use of less-lethal (aka: MI4 Stingers), semi-lethal (aka: MI4 Stunners), lethal (aka: MI4 Stoppers) and traditional slugs loaded in a particular sequence and then fired from a single gun to deliver varying levels of stopping power. If the situation requires, a shooter can transition from a less-lethal to a lethal response as fast as they can pull the trigger (fraction of a second), without running the risk of applying insufficient or excessive force – thereby creating for the first time a one gun solution for anyone finding himself in a difficult situation.



Modern high velocity bullets are notoriously over-engineered in such a way that they will often over penetrate through live targets and or walls of a house and still have enough energy to kill innocent bystanders on the other side. The company’s one room Smart-Stop technology is engineered to solve this problem by combining the proprietary flight characteristics of a MI4 bullet with a modified shot profile (adjusting mass, velocity and tether strength), thereby eliminating unwanted over penetration.


MI4 Stinger:

This category of bullet will be made from a low density material (e.g. aluminum, plastic, rubber, etc.) and fired at a relatively low velocity. It is designed to inflict pain/bruises/minor lacerations, but not penetrate deeper tissues. This non-lethal version provides the shooter with a bullet that will give him tactical advantages to gain control in a difficult situation by delivering a debilitating sting, with virtually no risk of killing the person.


MI4 Stunner:

This category will be made from a medium density material (e.g. copper, zinc) and be propelled at a mid-range velocity. It is designed to “stun” a person (i.e., break skin, penetrate secondary and tertiary layers of tissue, knock down), but not intentionally penetrate deep into vital internal organs. A person hit with a single “stunner” round would be substantially debilitated and would require immediate medical attention, but would not likely be killed if medical attention is administered in a timely manner.


MI4 Stopper:

This category of bullet will be made from a high density material (e.g. lead, tungsten) and will be propelled at the highest possible speeds, resulting in a high mass, high velocity round that delivers the necessary stopping power for a one shot kill. As its name suggests, it is designed to “permanently stop” (i.e. kill) a target.


  Multiple Impact Technology

A multi-part bullet composed of three interlocking projectile segments interconnected like a spider's web with high strength fibers. Immediately after leaving the tip of a rifled barrel, the segments unlock and expand to a predetermined diameter and pattern of spread.


Stopping Power:

Describes the ability of a projectile to cause a penetrating/damaging ballistic injury upon impact with a live human or animal target. Subjectively measured but simply summarized as the amount of damage caused by a ballistic projectile to force the capitulation or incapacitation of an assailant or animal.



Our proprietary dual functioning tether and brake component that first allows for a rapid radial expansion of the segments, then gradually arrests the outward movement activating only as much of the pressure sensitive braking system necessary to suspend the segments into orbit at a fixed distance around the original center of rotation.


Wide Envelopment Bullet (W.E.B):

A MI4 Wide Envelopment Bullet is a bullet enhanced with our Triple Threat Technology (MI4). The MI4 is the same in every way to conventional bullets when comparing their compatibility to existing guns. The performance is the same up until the point where the bullet leaves the barrel of a rifled gun, at which time its three identical segments and the interconnecting tethers spread out like a spiders web (W.E.B) producing a unique wide enveloping shot profile for an ultra-high hit probability.
