DEFINITIONS
MACHINE PISTOL- R.P.M.

MACHINE PISTOL
An automatic weapon which in general terms utilizes pistol or revolver ammunition.

MAGAZINES See Chargers, Clips and Magazines

MUZZLE BOOSTER
A device attached to the muzzle end of the barrel, which utilizes the explosive discharge gases for a more rapid movement of the recoil mechanism during the mid portion of the firing cycle to increase the rate of firing.

MUZZLE BRAKE
A device attached to the muzzle end of the barrel so designed as to deflect a percentage of the propellant gases in a variety of direction to lessen the recoil shock.

OPEN BOLT SYSTEMS See closed and Open Bolt Systems.

RATE OF FIRE
The timed repetition of firing between rounds in automatic weapons. Usually described in and referred to as rpm.

RECEIVER [FRAME]
The main body of a firearm that contains the operating mechanism of which the barrel and stock, if any, are attached.

RECOIL OPERATION
A common system for controlling the cartridge movement of automatic weapons. [See also gas operation]. This method utilizes the cartridge propellant explosion pressure to drive the shell casing rearward against the bolt forcing it rearward sufficiently to eject the spent round and reload the next round into the chamber. The combination of recoil spring pressure and chamber pressure drop timing provides bolt travel at a controlled speed and smooth rate.

ROTARY BOLT LOCKING
Also see Bolt Lock.
The rotating of a bolt in position to a barrel extension or forward portion of the receiver to lock it in place for firing of the cartridge.

ROTATING MOUNT See flexible mount.
