Advantages
Compared to a closed-bolt design, open-bolt weapons generally have fewer moving parts. The firing pin is usually part of the bolt, saving on manufacturing costs. In automatic weapons an open bolt helps eliminate the dangerous phenomenon known as "cook-off", wherein the firing chamber becomes so hot that rounds spontaneously fire without trigger input. Open-bolt designs typically operate much cooler than closed-bolt designs, making them more suitable for constant full-automatic weapons such as machine guns.

Famous quotes containing the word advantages:
“If the minds of women were enlightened and improved, the domestic circle would be more frequently refreshed by intelligent conversation, a means of edification now deplorably neglected, for want of that cultivation which these intellectual advantages would confer.”
—Sarah M. Grimke (1792–1873)
“The advantages found in history seem to be of three kinds, as it amuses the fancy, as it improves the understanding, and as it strengthens virtue.”
—David Hume (1711–1776)
“When the manipulations of childhood are a little larceny, they may grow and change with the child into qualities useful and admire in the grown-up world. When they are the futile struggle for love and concern and protection, they may become the warped and ruthless machinations of adults who seek in the advantages of power what they could never win as children.”
—Leontine Young (20th century)
