Abstract
A firearm safety round configured to function as a safety round for the following firearms: SAR 21—Singapore Assault Rifle-21st Century and M-16 rifle. The safety round includes a cylindrical rear end having a rim, a mid-section adjacent the rear end opposite the rim, the mid-section comprises a truncated cylinder having opposite flat sides, a tab extending outwardly from the mid-section and configured so that when the safety round is received by the firing chamber, the tab will extend out of the firing chamber to visually indicate that the firing chamber of the firearm is free of live ammunition and a cylindrical nose portion extending from the mid-section, opposite from the rear end and longitudinally aligned therewith. When the safety round is installed in the firing chamber of the firearm, one of the flat sides rests on the firing chamber and positions the rim in alignment with the extractor, and the flat sides configure the mid-section so that a largest dimension of the mid-section is smaller than a height of the extraction port of the firearm.
