Frequently Asked Questions

What is the Nylaug firearm?

The Nylaug is a 3D-printed receiver designed to accept parts kits from Steyr or SME AUG firearms. It offers a significantly more affordable entry point into the AUG platform, with complete builds costing around $790.

What materials are recommended for printing the Nylaug receiver?

It is crucial to print the Nylaug receiver using heat-resistant Nylon, specifically Polymaker PA6-CF20. Using materials like PLA or ABS is strongly discouraged as they will melt under the operational heat generated by the barrel.

How does the Nylaug compare in price to a factory Steyr AUG?

A complete Nylaug build from Titus Arms is priced at approximately $790, which is substantially less than a factory Steyr AUG, typically costing around $1,700, making it a highly cost-effective option.

Can the Nylaug be configured for different calibers or ejection?

Yes, the Nylaug community has developed barrels for calibers like .300 Blackout, and specific left-handed bolts and stocks can be sourced for left-hand ejection configurations, offering significant customization.
