Clips: How Hard is it to Misassemble a Ross Rifle?

Published on September 24, 2021
Duration: 6:03

This video demonstrates how the bolt of a Ross Rifle can be incorrectly reassembled, leading to a dangerous unsecured breech. The presenter shows that by rotating the bolt head less than a quarter turn during reassembly, the locking lugs will not engage properly. This allows the bolt to be closed and the safety to be set to a position that would normally secure the action, yet the breech remains unsecured and can be opened without an unlocking cycle, posing a significant risk of firing out of battery.

Quick Summary

The bolt of a Ross Rifle can be dangerously misassembled by rotating the bolt head less than a quarter turn during reassembly, preventing the locking lugs from engaging. This leads to an unsecured breech, allowing the rifle to fire out of battery, a highly dangerous condition. Modifications like a pin in the bolt shroud are common to prevent this issue.

Frequently Asked Questions

How can the bolt of a Ross Rifle be dangerously misassembled?

The bolt head of a Ross Rifle can be misassembled by rotating it less than a quarter turn during reassembly. This incorrect orientation prevents the locking lugs from engaging the receiver's raceway, leading to an unsecured breech.

What are the signs that a Ross Rifle bolt has been misassembled?

Signs of a misassembled Ross Rifle bolt include excessive resistance and stiffness when closing the action, requiring significant force to 'whack' it shut. The bolt lugs should also be visible in the receiver's raceway when the action is closed, indicating it is not locked.

What is the danger of a misassembled Ross Rifle bolt?

A misassembled Ross Rifle bolt results in an unsecured breech. This means the firearm can be fired out of battery, which is extremely dangerous and can cause catastrophic failure of the rifle and severe injury to the shooter.

How were Ross Rifles modified to prevent bolt misassembly?

Most Ross Rifles encountered today have been modified with a pin installed in the bolt shroud. This pin acts as a guide, preventing the bolt head from being oriented incorrectly during reassembly and thus preventing the unsecured breech condition.
