Frequently Asked Questions

How can I fix an overgassed rifle like the WWSD?

To fix an overgassed rifle, you can shorten the barrel to reduce dwell time and gas pressure. Additionally, installing an adjustable gas block allows for precise control over the gas entering the system, mitigating overgassing, especially when using suppressors.

What are the benefits of a shorter barrel on a rifle?

A shorter barrel reduces dwell time and gas pressure, which can help with overgassing. For pencil-profile barrels, shortening them can increase rigidity, potentially leading to improved accuracy despite a slight loss in muzzle velocity.

Why would someone shorten a rifle's stock?

Shortening a rifle's stock, or reducing its length of pull, is often done to improve handling when wearing body armor like a plate carrier. It also accommodates optics with very short eye relief, allowing for a proper sight picture.

How can I make an AR-15 receiver more rigid?

You can reduce play between the AR-15 upper and lower receivers by shimming the interface. This is typically done by inserting small pieces of material, such as hammered brass, into the gaps to create a tighter fit and enhance the firearm's sturdiness.
