Carbines

Firearms — Subcategory

Overview

A carbine is a shorter, lighter version of a rifle or musket — typically 10–12 inches shorter in barrel length — designed for use by soldiers for whom a full-length long arm is impractical. Cavalry could not easily wield a full-length musket from horseback; tank crews, paratroopers, and vehicle infantry have similar constraints. The carbine trades some range and ballistic performance for maneuverability and reduced weight.

Cavalry Carbines (1700s–1900s)

Flintlock Cavalry Carbine

The first carbines were shortened muskets for cavalry:

• Roughly 30-inch barrel vs. 42–46 inches for infantry muskets
• Carried in a leather bucket on the saddle or on a sling
• Used from horseback or dismounted in skirmish roles

American Civil War Carbines

The Civil War saw an extraordinary proliferation of cavalry carbine designs, driven by competing inventors and wartime demand:

• Sharps Carbine — Single-shot breech-loader; .52 caliber; reliable and accurate; issued to Union cavalry in large numbers; the weapon of Berdan's Sharpshooters in rifle form
• Spencer Repeating Carbine — 7-round tube magazine in the buttstock; .52 rimfire; the decisive cavalry weapon of the war; Confederate forces said it was "that Yankee rifle you could load on Sunday and shoot all week"
• Burnside Carbine — Distinctive tapered metallic cartridge; 5th most produced carbine; issued to Union cavalry
• Smith Carbine — Rubber cartridge; widely issued
• Henry Carbine — 16-round lever-action; precursor to the Winchester; privately purchased

Late 19th-Century Carbines

• Springfield Trapdoor Carbine — Single-shot breech-loader; used at Little Bighorn (1876) by the 7th Cavalry
• Krag–Jørgensen Carbine — Bolt-action; US cavalry weapon of the Spanish-American War era

20th-Century Carbines

M1 Carbine (1942)

The US M1 Carbine was developed for support troops who needed a firearm but couldn't use the full-size M1 Garand:

• .30 Carbine — A new pistol-length bottlenecked round; intermediate between pistol and rifle cartridge
• 6 lbs loaded — Roughly half the Garand's weight
• 15 and 30-round magazines — The M1A1 paratrooper variant had a folding stock
• Criticized for insufficient stopping power; praised for light weight; produced in enormous numbers (over 6 million)

German MP 43/StG 44

While technically an assault rifle, the StG 44 represents the convergence of carbine and rifle in a single weapon — intermediate cartridge, controllable automatic fire, rifle-length effectiveness.

Modern Carbines

• M4 Carbine — The shortened M16; 14.5-inch barrel vs. 20-inch; the current standard US military weapon; widely adopted worldwide
• HK416 — Piston-driven M4 derivative; used by US special forces and many NATO armies
• AKS-74U ("Krinkov") — Shortened AK-74; used by Soviet and Russian forces; very compact
