A short or rough chamber on a gas-operated firearm can cause which type of malfunctions?

A short or rough chamber on a gas-operated firearm can lead to a range of malfunctions, affecting various operational stages of the firearm. When the chamber is not properly sized or has surface irregularities, it can cause the cartridge to not seat correctly, leading to feeding issues. This improper alignment can also interfere with the locking mechanism, preventing the bolt from securing fully in place, which is vital for safe operation. Furthermore, a rough chamber can impede the extraction process; spent casings may stick and fail to be ejected properly. Therefore, the presence of a short or rough chamber can indeed result in feeding, locking, and extracting malfunctions, encompassing all types listed.
