摘要： A rotating bolt firearm may be configured to fire a .308 cartridge. However, the firearm may have a reduced weight in comparison to standard .308 rifles. The firearm may have many components typically used in a .223 rifle. The firearm may include a barrel extension with an extractor gap, which allows a .308 bolt to fit within a .223 sized barrel extension. The firearm may comprise an elongated magazine well in comparison to a .223 mil-spec rifle. The firearm may weigh less than 6.8 pounds with a 16 inch barrel, or less than 6.3 pounds with a 10.5 inch barrel.

摘要： A conversion kit for converting a semi-automatic or self-loading handgun of a certain caliber, such as a Colt .45, is modified to allow the use therein of cartridges of a different, usually smaller caliber, thus to allow less expensive training on the handgun, wherein only the barrel and magazine need to be replaced, the barrel having thereon a sliding extractor that cooperates with the original slide in the ejection and reloading of cartridges, and an off-axis bore adjusted to compensate for the difference in the reloading mechanism and the lesser rise of the handgun when firing the lower caliber ammunition, thereby allowing retention of the sighting, safety features, and mechanical functions of the original handgun while closely duplicating the original weight.
