Sturm Ruger AC-556K .223REM Transferable Factory 4-Position Select Fire Machine Gun

$19,000.00

Status: SOLD

This Chester County Armory listing is for a Sturm Ruger AC-556K .223REM transferable factory machine. It is in it’s original factory “K” or “short” condition, meaning it features the shorter 13″ original factory barrel, as well as it’s original iconic folding Ruger stock.

One of the few factory-made 4-position (safe, semi-auto, three round burst, and full-auto) machine guns made in the US, the Sturm Ruger AC-556 is still one of the more desired full-auto weapons available at a relatively reasonable NFA price tag left on the US transferable market. Designed and built like all of Ruger’s weapons (robust, with exceptional functionality), Bill Ruger’s entry into Class 3 weapons with the AC-556 was no different.  Designed in 1979 and based off the semi-auto Mini-14 that he (along with Jim Sullivan) created 6 years earlier as a scaled down version of the venerable M14 rifle, Ruger developed a workhouse of gun, utilizing new manufacturing and engineering techniques to build a robust weapon that would be affordable to produce without sacrificing durability in any way, namely creation of a strong, investment cast receiver that was heat treated to withstand even the harshest of punishment.

This factory-made and registered machine gun is in excellent overall condition. The internal mechanics and the interior metalwork are excellent, with no dings, dents, cracks,  malformations, etc.. The internals on this weapon note only minor finish wear on the metal-to-metal contact points of the bolt and charging handle assembly. The bolt face is clean and crisp. The barrel is clean, bright, and shiny, with excellent rifling. Cosmetically, the bluing of the receiver displays minor surface scratches and handling marks, and there are some minor scratches of note on the original rear sight assembly. There are some minor indentations and light surface marks on the wooden stock, but no chips, cracks, etc.. The stock lock-up remains tight and solid. The handguard and barrel are in excellent cosmetic condition, with only some minor storage wear noted on the front sight blade. Overall, this is an excellent investment model for the collector who also wishes to fire his machine guns.

According to the previous owner, Several years ago, this weapon was sent back to Ruger for their (no longer offered) full inspection and upgrade service for Class 3 Weapons. This process allowed Ruger to fully inspect the machine gun and replace any necessary worn or broken parts as necessary, to make the gun perform in the same condition as the day it first left the factory. The previous owner stated that after receiving it back from Ruger, having completed their full gunsmith inspection and upgrades, that this weapon has never been fired. It was safely stored and put away for investment purposes.

This factory transferable AC556K machine gun is currently on a Form 3 for easy eForm transfer. The current NFA paperwork lists “Sturm Ruger” as the manufacturer of this weapon and “AC-556K” as the model.
