Do you know if the gasport of your fieram needs to be tuned? If you are experienced Stovepiping, this may be the case. In this article, we will be discussing the effects of the higher velocity and the different exit angles on the bolt during its forward motion.
The True Velocity Polymer case is far lighter than the traditional brass cartridge case. In fact, they are up to 60% lighter in select traditional brass cartridge case calibers. This reduced mass results in higher bolt speeds when cycling, which in turn outcomes in the spent case having a high velocity as it flees the firearm and rebounds off the deflector.
In addition, the center of mass of the True Velocity case is much closer to the aft end of the case than in a traditional brass cartridge case. This results in a different rotation of the case as it is extracted from the weapon. In certain scenarios, a change of direction of the ejected case. For instance, if a brass case exits the firearm at 3 o’clock, a True Velocity deposit case exits at 1 o’clock.
On occasion, the higher velocity and the different exit angle can result in a case being caught by the bolt during its forward motion. This is also referred to as Stovepiping. In these types of cases, it is suggested that the gasport should be lessened so that the weapon cycles correctly without forcing the bolt quite as hard.
Please keep in mind that work such as this should always be executed by a qualified gunsmith to ensure safety in the firearm during the job being done and afterward for firing properly to prevent more issues and harmful injuries to the firearm operator.
What is the Gasport on a Gun?
The gasport of a firearm is also referred to more generally as the gas operation or gas system. A Gas-operation is a system of function in autoloading firearms with the purpose of providing energy to operate locked-breech. In gas operation, an amount of high-pressure gas from the cartridge being fired is employed to power a mechanism to dispose of the finished case and insert a new cartridge into the chamber.
This high-pressure gas of a gasport has sufficient power to destroy a firearm unless it is regulated somehow. Most gas-operated firearms depend on fine tuning of the gasport mass, size, and spring pressures to function.
