Reconbolt

A Recon CS-6's breech.

A breech (also called a bolt) is an internal component found on breech-loaded blasters as well as most clip system Nerf blasters.

Details[]

A bolt consists of two parts: The breech itself and the breech sled. The breech sled moves the bolt and is attached to the priming mechanism. When the blaster is primed back and forth, the bolt grabs a dart from the clip, when it reaches the end of its cycle, a dart tooth helps push the dart all the way down on the dart post in the breech.

Breech-loading[]

In breech-loading blasters like the IonFire, the breech is placed upside down, so that when the breech is opened, it can allow the user to place in a dart.

Pusher breech[]

A pusher breech is a type of breech found on some hobby-grade blasters such as the Nexus Pro, or can be installed in other blasters using mod kits. Unlike conventional breeches, pusher breeches push darts forward into a chamber located behind the barrel, rather than having their own chamber. Pusher breeches do not have dart posts and do not require dart teeth, and usually do not have air restrictors. Due to this, they are less prone to jamming.[citation needed] Pusher breeches can also be designed to be compatible with both full-length and half-length darts.

Spring-powered RIVAL and Hyper blasters also use a pusher breech, however, they also make use of an air restrictor. Blasters with pusher breeches can also use a compression barrel.

Buzz Bee blasters that use both shells and clips (such as the Rapid Fire Tek) technically also use pusher breeches, although the effective barrel itself is located in the shell and not in front of the breech.

Pusher breeches do not need to be bigger than the diameter of a dart since they do not house the dart, so they can be made thinner than a regular breech. A variant of the pusher breech, known as a skinny pusher, VanGuard breech, or dogbone pusher, as its name suggests, has a much narrower section in the middle, which allows clips to be removed without damaging them at all, even when the breech is forward. Skinny pushers are often made of metal since there is less material and making it out of plastic makes the component weaker. The Game Face Trion is an example of a blaster that uses a skinny pusher.

Modification[]

Some modders remove the air restrictor from the bolt, and add brass into the breech. This helps air flow and increases performance.
