The Fortis Standard Castle Nut is a lightweight, precision-engineered component designed for operators and builders seeking to reduce system weight without compromise. This castle nut threads onto mil-spec buffer tubes and serves as a critical interface in the receiver extension assembly.
Manufactured from 7075-T6 aluminum, this material is favored in aerospace applications for its excellent strength-to-weight ratio. The construction ensures reliable performance, allowing the castle nut to secure the buffer tube effectively.
This component is ideal for builders focused on lightweight rifle builds, whether for long-range precision, CQB mobility, or competition shooting. It works with standard mil-spec buffer tube assemblies and requires a standard castle nut wrench for installation, making it a versatile choice for shooters and gunsmiths.
