Frequently Asked Questions

What causes the bolt lock on a Ruger Mini-14 to stick to the rear?

The most common cause is debris, such as glass bedding compound, obstructing the bolt plunger hole. Dirt, dust, or carbon buildup can also impede its movement, preventing the bolt from releasing.

How do you properly orient the bolt lock when reinstalling it on a Ruger Mini-14?

The bolt lock has a specific notch that must face directly towards the rear of the firearm. This orientation is crucial for it to correctly engage the corresponding leg on the receiver when the bolt is cycled.

Should I lubricate the bolt lock plunger on my Ruger Mini-14?

No, you should never grease or oil the bolt lock plunger. Lubricants can attract dust and debris, leading to jamming, especially in cold or dusty environments. There is no internal mechanism requiring lubrication there.

What is the function of the bolt lock plunger on a Ruger Mini-14?

The bolt lock plunger, when depressed, allows the magazine follower to engage with the bolt lock mechanism. This interaction holds the bolt securely to the rear, typically after the last round has been fired.
