Abstract
A projectile may include a body and a base fixed to a rear end of the body. The base may include a gas cavity and an opening extending from a rear end of the base to the gas cavity. A retention plug may be disposed in the opening wherein a fit between the retention plug and the opening is such that propellant gas pressure in the gas cavity forces the retention plug out of the opening. The retention plug may include at least one gas conduit between an outer surface of the retention plug and the gas cavity. A plurality of fins may be rotatably fixed to the base. The fins may have a folded position and a deployed position.
