Description Penetrating power. The .50 Browning Machine Gun (BMG) round pierces steel armor, decimates vehicle engine blocks, and lacerates enemy air craft. Now you can put this power in the palm of your hand…or at least a bottle opener version of it. Recycled from fired rounds, these are just like the real ammo developed to answer the call for anti-aircraft and anti-vehicular loads after World War I (because they are!). During WWII, the cartridge was mostly fired from M2 Browning machine guns. Today, the military also uses .50 chambered rifles to obliterate enemy forces. Our .50 BMG bottle opners won’t annihilate your adversaries, but arms enthusiasts or military member will go ballistic for these as a novelty that also serves an important post-mission purpose. This version features a blackened finish with a copper-plated tip, and has the Ranger Industries logo with a battle hardened American Flag graphic. Each bottle opener measures 5.8 inches in length and 0.85 inch diameter at the base.
