1. Brown Bess Musket
Used by British forces from the early 1700s through the Napoleonic Wars, the Brown Bess was a flintlock musket that became a symbol of colonial-era warfare.

2. Springfield Model 1861
A staple of the Union Army during the American Civil War, the Springfield Model 1861 was a .58 caliber rifled musket. Its improved range and accuracy over smoothbore muskets gave Northern forces a distinct advantage. Over a million were produced, making it one of the most widely used weapons of the conflict.
3. Winchester Model 1873
Dubbed “The Gun That Won the West”, the Winchester Model 1873 was a lever-action rifle favored by settlers, cowboys, and lawmen alike. It combined reliability, fast cycling, and accuracy, becoming a cultural icon of the American frontier. It also saw limited use in military conflicts across the globe.
4. Mauser Gewehr 98
Germany’s standard-issue rifle in World War I, the Gewehr 98 featured a bolt-action design that became the gold standard for military rifles. Its five-round internal magazine and long-range accuracy influenced countless future rifles, including the famous American Springfield M1903.

The standard service rifle for the U.S. military since the Vietnam War, the M16 brought lightweight materials and high-velocity rounds to the battlefield. Despite early reliability issues, the rifle evolved into a highly effective and modular platform still in use today by many NATO countries.

9. Mosin-Nagant
A rugged and simple bolt-action rifle, the Mosin-Nagant was the workhorse of the Russian and Soviet armies from the late 1800s through WWII. Its accuracy and bayonet length made it a formidable weapon, and it’s still used by militia and reserve forces in some parts of the world.
10. StG 44
Widely considered the world’s first true assault rifle, the German StG 44 introduced the concept of intermediate cartridges and selective fire. Though it came late in WWII, it influenced post-war designs like the AK-47 and changed how infantry weapons were conceptualized.
11. Thompson Submachine Gun
The “Tommy Gun” became infamous during the Prohibition era but also proved itself in WWII and beyond. It offered fully automatic fire in a compact size and was favored in close-quarters combat. Its distinctive design and high rate of fire made it a legend on both sides of the law.
12. MG42
Nicknamed “Hitler’s Buzzsaw,” the German MG42 had a terrifyingly high rate of fire, up to 1,200 rounds per minute. Used primarily in World War II, its design was so effective that post-war machine guns, such as the American M60, were directly inspired by it. It was feared and respected by Allied forces.
13. FN FAL
Often called “the right arm of the free world”, the FN FAL was adopted by NATO allies during the Cold War. Its semi-automatic fire and 7.62mm NATO round made it powerful and versatile. It saw action in conflicts across Africa, South America, and the Middle East.
14. Colt M1911
Designed by John Browning, the M1911 is one of the most iconic pistols in military history. Used by U.S. forces for over 70 years, its .45 ACP round delivered serious stopping power. Reliable and easy to maintain, many still swear by it to this day.
15. MP40
This German submachine gun was widely used during WWII and favored for its compact size and control in automatic fire. Unlike the Thompson, it had a slower rate of fire, making it more accurate in close-quarters combat. It became a staple of German infantry squads.
16. Dragunov SVD
Introduced in the 1960s, the Dragunov served as the Soviet Union’s designated marksman rifle. Designed for medium-range accuracy rather than traditional sniping, it allowed infantry units to reach out further with semi-automatic fire. It remains in use around the world.

A game-changer in long-range warfare, the Barrett M82 is a semi-automatic anti-materiel rifle capable of disabling vehicles and equipment from extreme distances. It gained notoriety in conflicts from the Gulf War to Afghanistan. Its .50 BMG round delivers immense power and range.
18. Glock 17
The Austrian-designed Glock 17 revolutionized military sidearms with its polymer frame and striker-fired system. Lightweight, durable, and boasting high magazine capacity, it became a standard issue for many military and police forces globally. It also helped reshape the civilian firearms market.
19. HK416
A modern evolution of the M4 platform, the HK416 uses a piston system for greater reliability. It gained fame when used by U.S. Navy SEALs, including in the mission that killed Osama bin Laden. The weapon reflects current trends in modularity and precision.
