DEFINITIONS
FLASH HIDER - GAS PORT

FLASH HIDER [SUPPRESSOR]
A device attached to the muzzle end of the gun barrel, which reduces muzzle flash but does not reduce muzzle blast. Not to be confused with “ muzzle brake” or “muzzle booster”.

FLEXIBLE MOUNT
A nonpowered gun mounting of which the gunner can move the weapon freely in vertical, [elevation], and/or horizontal, [traverse] direction.

FIRING PIN, FLOATING
A free traveling firing pin that is held in spring tension within the bolt and remains compressed until the live cartridge is in battery, then released by the sear/hammer assembly to contact the cartridge primer for firing.

FIRING PIN, FIXED

A nipple or bead that is milled into the face of the gun bolt and contacts the cartridge primer at the last moment of battery. The bolt itself under tension serves as the activator. The system is most common in “open bolt” firing automatic weapons. [Also see closed and open bolt systems].

FLUTED BARREL
Longitudinal grooves cut in barrel exterior to maintain rigidity during weight reduction, elimination of mass and increased cooling effect on automatic weapon applications. Reference: Italian Machine Pistol MP 38/42 series.

FURNITURE
In early firearms it was referenced as the metal components excluding moving parts and barrel. In recent times it is more referred to as the wooden elements of the gun.

GAS OPERATION
One of two popular methods to provide necessary mechanism operation of automatic weapons. [See also recoil operation]. The method is trapping and controlling a portion of exploding gas propellant from a ported barrel. The gas is directed into a cylinder containing a piston connected to the bolt assembly. The resultant pressure creates the movement for the reloading cycle.

GAS PORT [ORIFICE]
A small hole drilled into the underside and toward the muzzle end of the barrel which siphons off a portion of the fired cartridge powdered gases to the bolt connected piston for reloading cycle movement. For certain weapons the speed action is controlled by a variable sized hole “gas regulator” mounted at the end of the piston cylinder.
