Harrington & Richardson Arms Company (or H&R) is an American brand of firearms and a subsidiary of JJE Capital Holdings.

[4] A new company, H&R 1871, Inc., was formed in 1991 and started production of revolvers, single-shot rifles and shotguns using original H&R designs.

H&R 1871, Inc. assets were subsequently sold to H&R 1871, LLC., a Connecticut LLC owned by Marlin Firearms Company in November 2000.

[6] JJE currently owns several firearms manufacturing companies, including Lead Star Arms and Palmetto State Armory.

[7] Though there has been no official statement, Palmetto State Arms' social media indicates that JJE may produce M1 Garand rifles under the H&R brand.

Its higher velocity[16] offers a flat trajectory, while the light weight of the bullet results in low recoil.

or ".22 Winchester Rim Fire" H&R produced muzzle loading firearms under the Huntsman and Sidekick models, during two different periods.

Both were based on the new threaded breech plug design; the Huntsman had the same lug pattern as the Pardner Shotgun and Handirifle lines produced at the time allowing for the Huntsman Barrel to be fitted to those actions while the sidekick had a shorter lug to pivot pin distance.

The difference in the barrel lug position made the Huntsman applicable to standard firearms laws requiring a background check as centerfire and shotgun barrels could be exchanged on the same receiver, while the Sidekick was considered a muzzle loading firearm and did not require a background check for purchase.

The Huntsman and Sidekick models were available in blued and stainless finish, fiber optic sights, and 24" or 26"(magnum) 1 in 28" twist barrels.

The new breech plug design utilized an orange Zytel plastic primer carrier that aligned the primer over the breech plug, could be removed easily with gloved or cold hands, and served as a flag indicator that the firearm was primed.

There were two different threaded breech plugs that were designed for the Huntsman and Sidekick lines, one 5/8 and the other 7/8 that utilized a proprietary tool to fit in a slotted head.

The program offered rifle, shotgun, and muzzle loading barrels to be fitted to receivers produced after 1987.
