Frequently Asked Questions

What are common causes of AR-15 short-stroking or ejection problems?

AR-15 short-stroking or ejection issues can stem from a worn gas tube, misaligned gas block, or worn gas rings on the bolt carrier group. These components affect gas flow, leading to insufficient cycling of the action.

How can I check for worn gas rings on my AR-15 bolt carrier group?

You can check for worn gas rings by assessing the tension of the bolt within the carrier. If the bolt reciprocates very easily with little resistance, it indicates the gas rings may be worn out and need replacement.

What is a critical maintenance point for shotguns to prevent extraction failures?

A critical maintenance point for shotguns is the extractor, which is often overlooked. It must be kept clean and free of rust to ensure proper function and prevent issues like pulling cartridge rims off.

Why are magazine springs important in high-capacity shotguns?

Magazine springs in high-capacity shotguns are crucial for reliably feeding ammunition. They are under significant stress and wear out over time, which can lead to malfunctions, especially with the last round in the magazine.
