Frequently Asked Questions

What are the key mechanical differences between the Joslyn M1862 and M1864 carbines?

The M1862 features a simple pivoting breech block with a blade-style extractor. The M1864 improves this with a spring-loaded latching knob for more positive breech closure and adds a shroud around the firing pin for protection.

What calibers did the Joslyn M1862 and M1864 carbines use?

The Joslyn M1862 carbine was chambered in a proprietary .54 caliber rimfire. The M1864 model transitioned to the .56-52 Spencer rimfire caliber to standardize with army ammunition.

Did Springfield Armory use Joslyn designs?

Yes, Springfield Armory purchased approximately 3,000 Joslyn breech assemblies to build their own infantry rifles. This marked a significant step in the government arsenal's production of breech-loading firearms.

What were some common issues reported with the Joslyn M1864 carbine in field use?

While some negative reviews existed, historical field tests often attributed issues like the breech popping open to poor quality Spencer ammunition rather than inherent design flaws in the carbine itself.
