Harrington & Richardson M14 7.62 NATO NFA Machine Gun, 22 in Barrel, Walnut Stock, Vietnam War Era Pattern, Match-Style Front Sling Setup
This Harrington & Richardson M14 stands out as a Vietnam War era, forged-steel receiver example with U.S. contract lineage. The receiver heel is marked 'U.S. RIFLE 7.62 MM M14 H.&R. ARMS CO.' and the rifle retains classic USGI features, including the 22-inch configuration, M14 gas system, and slotted flash suppressor with bayonet lug.
The action is bedded into the walnut stock, and a forend weight appears to be installed, offering a distinct, purpose-built setup. Under long-standing ATF interpretation, any original M14 receiver is a machine gun regardless of removal of selector parts; listing/selling it as a non-NFA semi-auto rifle is incorrect unless it is an NFA-registered MG.

Harrington & Richardson was a U.S. government M14 contract maker, and this rifle reflects that pedigree with its forged steel receiver and correct heel marking. The receiver is explicitly marked 7.62 mm, and it follows standard M14 receiver geometry with a stripper-clip guide.
The rifle retains many core M14 service features: a 22-inch configuration with the M14 gas system, including the gas cylinder, gas lock, and hex-head gas plug. Note that the standard bottom-position gas-cylinder front sling swivel is absent; in its place is a side-mounted sling loop on a screwed-on fore-end plate, a common match/competition modification. At the muzzle, it wears the USGI slotted flash suppressor with an integral front sight base and bayonet lug, secured by a knurled flash suppressor lock nut.
Sighting equipment is the M14 aperture rear sight, adjustable for windage and elevation, paired with a protected front blade on the flash-suppressor base. Furniture includes a walnut stock with a metal buttplate, flip-up shoulder rest, and trapdoor buttplate, plus front and rear sling attachments. The front sling attachment is the side-mounted plate described above, with the gas-cylinder/band bottom swivel not present. A ribbed fiberglass top handguard completes the pattern. Length of pull is 13.0 inches.
Notable receiver details include the selector shaft boss with the selector hardware absent and plugged. The bolt is marked with drawing number '7790186' and a partial lot code. The action is bedded into the stock, and a weight appears installed in the forend via the magazine well, contributing to the rifle’s distinctive setup.
