Abstract
Apparatus for converting a semi-automatic weapon into a single shot weapon. In one embodiment, the lower receiver of the weapon is replaced by a lower receiver that has no magazine well. The replacement receiver contains a loading block that can be loaded through the ejection chamber of the weapon. A spring biased plunger is provided in the replacement receiver for moving the bolt catch into a holding position when the bolt is moved into a battery position. In a second embodiment of the invention a dummy magazine is permanently secured in the magazine well and contains a loading block that can be loaded with a cartridge through the ejection port of the weapon. A spring biased plunger is mounted in the dummy magazine behind the loading block that is arranged to bias the bolt catch of the weapon into a bolt retaining position when the bolt is in a battery position.
