Driving bands and obturator rings are made from material that will deform and seal the barrel as the projectile is forced from the chamber into the barrel. Sabots use driving bands and obturators, because the same manufacturing tolerance issues exist when sealing the saboted projectile in the barrel, but the sabot itself is a more substantial ...
The original patent filed by Hermann Gerlich in 1932 [6]. The squeeze bore concept was first patented by German inventor Carl Puff in 1903 [7] [8], even though the general principle was known already in 19th century and later applied in lighter fashion on Armstrong guns, on which only the muzzle yet not the barrel itself was of slightly smaller diameter (to cast off the sealing leather-bag ...
Obturation is the necessary barrel blockage or fit in a firearm or airgun created by a deformed soft projectile. [1] A bullet or pellet made of soft material and often with a concave base will flare under the heat and pressure of firing, filling the bore and engaging the barrel's rifling.
A driving band or rotating band is a band of soft metal near the base of an artillery shell, often made of gilding metal, [1] copper, or lead. When the shell is fired, the pressure of the propellant swages the metal into the rifling of the barrel and forms a seal; this seal prevents the gases from blowing past the shell and engages the barrel's ...

Decoppering is the act of removing copper and it is most commonly used in the context of the removal of copper residues from the rifling of gun barrels. [1]Decoppering agents are frequently added to smokeless powder propellants.
Olympic was the first to introduce features now seen as commonplace on AR-15 rifles. It was one of the first companies to produce free floating aluminum hand guards, pistol caliber conversions, and AR-15-based pistols. Olympic manufactured many AR-15s in calibers other than the standard 5.56×45mm.
