This entry details the disassembly and safety inspection of Ross Rudd's unique AR-180 prototype, which features a custom delayed blowback system. The guide, presented by firearms expert Ian McCollum, covers the removal of the bolt and carrier, inspection of key components like the locking recess plate and the firing pin safety mechanism. It highlights the innovative engineering behind Rudd's design, emphasizing safety checks crucial for experimental firearms.

Quick Summary

Ross Rudd's AR-180 prototype is distinguished by its custom delayed blowback system, which uses an angled bolt wedge locking into the receiver to delay opening until pressures drop. It also features a critical firing pin safety that only aligns when the bolt is fully in battery, enhancing safety.

Frequently Asked Questions

What makes Ross Rudd's AR-180 prototype unique?

Ross Rudd's AR-180 prototype is unique because it features a custom-designed delayed blowback operating system, deviating from the standard gas operation of the original AR-180. This system uses an angled wedge on the bolt to lock into the receiver, delaying opening until pressures decrease.

How does the delayed blowback system on Rudd's AR-180 work?

The system employs an angled wedge on the bolt that engages with a locking recess plate inside the upper receiver. This geometric lock delays the bolt's rearward movement after firing, allowing dangerous chamber pressures to drop before the action cycles, similar in principle to HK's roller-delayed systems.

What safety features are present on Ross Rudd's prototype rifle?

A significant safety feature is the firing pin alignment mechanism. This ensures the firing pin can only align and strike the primer when the bolt is fully closed and locked into battery, preventing accidental discharges from an out-of-battery condition.

Who was Ross Rudd and what was his background in firearms?

Ross Rudd was a firearms designer born in Toronto in 1915. He worked for Savage Arms during WWII on Lee-Enfield and Thompson production and later founded Rudd Arms to develop his own firearm locking systems, starting with pistols and this AR-180 rifle prototype.
