It may or may not depending on the projectile and velocity.
Barrel length is measured from the bolt face to the end of the barrel.
It can.
No
It is completely dependent on you paint quality, how it matches the barrel and the consistency of your propellant, the gun itself may only affect %10 or less of accuracy.
The one I have has a 20 inch barrel.
It may or may not depending on the ammunition used.
It can be, depending on the action the gun uses. It can also be illegal if you cut the barrel length below the legal limit. In the US, a Title 1 rifle must have a minimum barrel length of 16 inches, and a Title I shotgun must have a minimum barrel length of 18 inches.
The main specifications of the Type 100 Submachine Guns include weight length and barrel length. The weight of the gun empty is 7.5 pounds, loaded is 9.7 pounds. The length of the gun is 35.4 inches. The barrel length is 9.1 inches.
The barrel has deep grooves milled into the outside of the barrel. Called flutes, the grooves reduce the weight of the barrel, yet leave it a stiff barrel with very good accuracy.
The loudness of a gun is primarily influenced by factors such as the type of ammunition used, the size of the gun, the barrel length, and the amount of gunpowder in the cartridge. Additionally, the environment in which the gun is fired, such as indoors or outdoors, can also affect the perceived loudness.
The usual minimum length is 18 inches measured from the face of the closed bolt. It is possible to own and possess a shotgun with a shorter barrel, but this requires obtaining a federal tax stamp ($200). Also shortening the barrel causes a loss of accuracy and a reduction in velocity of the shot.
YES! Especially CO2 systems.
