The term is often treated synonymously with Nerf Blaster, as Nerf was the first brand to start producing blasters, [1] and has since remained the most notable producer of them.
Before the barrel can release the bullet in a consistent manner, it must grip the bullet in a consistent manner. The part of the barrel between where the bullet exits the cartridge, and engages the rifling, is called the "throat", and the length of the throat is the freebore. In some firearms, the freebore is zero as the act of chambering the ...
A muzzle brake or recoil compensator is a device connected to, or a feature integral (ported barrel) to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. [1] Barrels with an integral muzzle brake are often said to be ported.

The armour-piercing gun evolution has also shown up in small arms, particularly the now abandoned U.S. Advanced Combat Rifle (ACR) program. The ACR "rifles" used smoothbore barrels to fire single or multiple flechettes (tiny darts), rather than bullets, per pull of the trigger, to provide long range, flat trajectory, and armor-piercing abilities.
If the foam weapon is to be an axe, a head carved out of open-cell foam may be affixed. Additional layers of closed-cell foam can be used to define a blade of a sword, the hilt of a dagger, or the soft foam "spikes" of a club. Foam weatherstripping is commonly used to better define a "cutting blade" as opposed to electrical tape.
