Franklin Armory Rabbit Rounds Bring Four-Projectile 5.56 Loads to AR Rifles

Franklin Armory is expanding from firearms and accessories into a distinctive ammunition category with Rabbit Rounds, a patent-pending 5.56x45mm cartridge that launches four spin-stabilized projectiles from an AR-pattern rifle. Announced in September 2026, Franklin Armory Rabbit Rounds are intended to give hunters a higher hit probability on fast-moving small game while retaining the familiar handling and capacity of the modern sporting rifle. For gun owners who value practical innovation and the freedom protected by the Second Amendment, this is an unusual load worth understanding before taking it into the field. The original details appear in the Franklin Armory Rabbit Rounds announcement.

How Franklin Armory Rabbit Rounds Work

Each cartridge contains four lead projectiles inside a multi-piece, self-discarding sabot. The sabot allows the projectile assembly to travel through the rifle barrel and receive spin from the rifling. After discharge, the sabot is designed to separate, leaving four spin-stabilized projectiles traveling toward the target. This produces a pattern more comparable to shotgun pellets than the single point of impact expected from conventional rifle ammunition, although the cartridge is still fired through a rifled AR barrel.

Franklin Armory lists the complete projectile assembly at 45 grains. From a 16-inch AR-15 barrel, the company reports a muzzle velocity of 3,150 feet per second and muzzle energy of 992 foot-pounds. Franklin Armory describes that performance as more than twice the typical speed and power of a shotshell. Those figures apply to the assembly and the specified test-barrel length; the announcement does not provide individual pellet weights, pellet dimensions, velocity at distance, or data for other barrel lengths.

The manufacturer says the imparted spin helps the four projectiles maintain an effective pattern beyond 40 yards. Franklin Armory President Jay Jacobson characterized the load as super-velocity, spin-stabilized shot that broadens the sporting capabilities of rifles chambered for .223 Remington and 5.56 NATO. Shooters should interpret the 40-yard statement as a manufacturer-reported effective pattern distance, not a guarantee of identical performance from every rifle.

Chamber Compatibility and Important Safety Checks

Franklin Armory Rabbit Rounds are identified as 5.56x45mm ammunition. The company states that they are intended for AR-pattern firearms chambered in .223 Remington, .223 Wylde, and 5.56 NATO. Because ammunition and chamber markings matter, owners should still read the final packaging, consult their firearm manual, and follow the rifle manufacturer’s ammunition guidance before firing the load. Never assume that every rifle can safely use a cartridge merely because it fits in the chamber or magazine.

Before hunting, shooters should also pattern the ammunition through the specific rifle, barrel, muzzle device, and sighting system they plan to carry. A multi-projectile load should be evaluated by the size and consistency of its overall pattern, not solely by the location of one pellet. Begin with a secure backstop at a conservative distance and examine how the pattern changes as range increases. Standard eye and hearing protection remain essential, and shooters must account for every projectile because one trigger press sends four separate projectiles downrange.

The announcement does not specify an MSRP, package quantity, recommended rifling twist, minimum barrel length, or suppressor compatibility. Until Franklin Armory publishes additional technical instructions, owners should not infer those details. A knowledgeable firearms dealer or the ammunition manufacturer can help answer product-specific questions that are not addressed on the box.

Small-Game Applications and Hunting Rules

Franklin Armory positions the load as an option for coyote, wild-pig, and other medium-game hunters who encounter smaller game and want a non-expanding, shotgun-like projectile pattern. The potential advantage is straightforward: four projectiles can increase the probability of connecting with a small, moving target compared with one conventional bullet. At the same time, ethical hunters remain responsible for knowing the load’s pattern, maintaining a safe field of fire, selecting an appropriate distance, and passing on shots that exceed their demonstrated ability.

Franklin Armory Rabbit Rounds do not eliminate the need to check hunting regulations. States can regulate legal calibers, projectile construction, magazine capacity, hunting methods, seasons, and allowable ammunition by species or geographic area. Because these projectiles contain lead, hunters must pay particular attention in jurisdictions or hunting zones that require nonlead ammunition. A load that is lawful for one species or parcel of land may not be lawful for another. Confirm current rules with the applicable state wildlife agency before carrying it afield.

Hunters should also remember that a patterned rifle load is not automatically interchangeable with a shotgun shell under game regulations. Wildlife rules may distinguish ammunition by firearm type, projectile type, or cartridge characteristics. Responsible compliance protects hunting access, supports conservation, and demonstrates the judgment expected from armed citizens exercising their Second Amendment rights.

Availability and What Buyers Should Know

According to the launch announcement, Franklin Armory Rabbit Rounds are available directly from Franklin Armory and through certified dealers. The company also plans to introduce Rabbit Rounds in additional popular hunting calibers, but it has not identified those chamberings or announced release dates. Buyers should avoid treating an unannounced caliber, price, or configuration as confirmed.

Franklin Armory operates from Nevada and develops firearms, accessories, and ammunition for sporting, defensive, and law-enforcement applications. The company says its products are designed, machined, and built in the United States. Readers can visit the official Franklin Armory website for current product information. The company directs media testing and evaluation requests to [email protected] and publishes product announcements through its official social channels.

Availability through a local gun store or online FFL dealer may vary, and ammunition sales are subject to federal, state, and local restrictions. Ammunition generally does not follow the same federal transfer process as a firearm, but some jurisdictions impose additional purchase, eligibility, shipping, or delivery requirements. Customers who want to buy guns online must have the firearm transferred through an eligible FFL, while ammunition orders must comply with the rules at the buyer’s destination.

A New Sporting Option for the AR Platform

Franklin Armory Rabbit Rounds combine a 45-grain, four-projectile assembly with a reported 3,150-fps muzzle velocity and 992 foot-pounds of energy from a 16-inch AR-15 barrel. The concept gives AR owners a novel small-game option without requiring a new firearm, but careful compatibility checks, real-world pattern testing, and strict attention to hunting law are essential.
