This video from CMMG explains the function and purpose of a floating firing pin in firearms. Mike, the presenter, breaks down what this specific component is and how it operates within a firearm's action. The description also includes promotional links to CMMG's website for insider information and their social media channels on Instagram and Twitter.
This video addresses a common concern among new AR-15 owners: a dented primer on an unfired cartridge. Brownells Gun Techs Steve and Caleb explain that this is a normal characteristic of firearms with a "floating" firing pin, such as the AR-15 and M16. When the bolt slams into battery, the inertia of the firing pin can cause it to briefly strike the primer. However, without the force of the hammer, this impact is insufficient to ignite the primer. The video demonstrates this phenomenon with a primed cartridge case, reinforcing that it is an intentional design feature and not an indication of a faulty rifle.
This video provides an in-depth look at the Sharps & Hankins Navy Model Carbine, a single-shot rimfire weapon designed by Christian Sharps. The description highlights its unique action, which levers the barrel forward, and its novel floating firing pin mechanism, a feature uncommon for its time (1850s-1860s). The example shown is a US Navy purchase, distinguished by a leather sheath on the barrel intended to protect against salt spray, though now often a liability for moisture trapping. The video delves into the technical aspects and historical context of this interesting carbine.
