Frequently Asked Questions

What makes the FoldAR AR-15 the most compact on the market?

The FoldAR AR-15 achieves its compact size primarily through its proprietary TMEP folding hinge mechanism, which allows the barrel to fold back against the receiver, significantly reducing its overall length for maximum concealment and portability.

What are the key components for building a FoldAR compact AR?

Essential components include the FoldAR proprietary upper receiver and TMEP folding hinge, a Maxim Defense SCW stock system for its ultra-compact footprint, and high-quality parts like Geissele triggers and Radian selectors for reliable function.

What is the recommended torque spec for the FoldAR barrel screws?

During the build process, the presenter emphasized using a precision torque driver to tighten the FoldAR barrel retention screws to exactly 30 inch-pounds (in/lbs), ensuring proper fitment and function.

How does the Maxim Defense SCW stock contribute to compactness?

The Maxim Defense SCW stock is a PDW-style system designed for an ultra-compact footprint. It requires a specific buffer tube and spring assembly to integrate correctly, minimizing the rifle's length when collapsed.
