FN FNC Rifle .223REM/5.56mm 17.7″ bbl Transferable S&H Arms Sear Machine Gun


Status: In Stock / Please Call to Purchase

This Chester County Armory listing is for a pristine condition FN FNC .223rem/5.56mm NATO fully transferable three position select-fire machine gun.

This collector grade condition machine gun was originally built by S&H Arms in Owasso, OK utilizing their own production, NFA registered transferable FNC machine gun sear. This sear was installed by S&H Arms into an FN FNC 17.7″ semi-automatic rifle with a full fixed stock. This particular FNC host rifle was built by Fabrique Nationale Herstal in their Belgium factory, and then imported into the US by the Steyr/Gun South partnership. All conversion work on this weapon was performed by S&H Arms. The lower on this model is four position ready, however, it was built by S&H Arms without the three round burst kit installed, so fire control operation positions are only SAFE, SEMI, and FULL-AUTO.  S&H Arms typically upgraded and marked all of their lowers with the four positions, even when they only installed three position controls in them.

Overall, this weapon is in excellent condition! This model has been thoroughly inspected and test-fired and runs flawlessly. Mechanically, the internals and fire controls show only very minor physical wear. The sear is in outstanding condition, with no noted wear. The bore and chamber remain bright and shiny with crisp, clean rifling.  The exterior metalwork of the host rifle is superb, with no dents, cracks, malformations, etc. noted.

Cosmetically, this weapon is in above average condition for a factory FNC.  The FN original finish on this model notes minimal scratches and marks in the exterior finish.  There is some minor wear on the painted parts at the ejection port, and some minor marks on the left side of the receiver, but no where near the typical amount of scratches seen on most converted FNC models. The original polymer furniture also notes only minor handling marks. Overall, this is weapon is in excellent cosmetic condition when compared to most NFA examples that maintain their original finish.

The current NFA paperwork indicates the manufacturer of this transferable registered sear as “S&H Arms” and the model as “FNC”. This model is currently on a Form 3 for fast and easy transfer via eForms. The host rifle transfers as a standard Title One rifle.
