Frequently Asked Questions
Will these pins fit any AR-15 lower receiver?
Yes. The Fortis Takedown Pin Set is machined to mil-spec tolerances of .247–.2485 inches, making them compatible with the vast majority of AR-15 mil-spec lower receivers from any major manufacturer. If your lower accepts standard mil-spec takedown and pivot pins, these will fit correctly. They are not designed for AR-10 or .308-platform lowers, which use a larger pin diameter.
What is the difference between case hardened and black nitride finishes?
Both finishes offer excellent durability and corrosion resistance, but they differ visually and in surface treatment process. Case hardening produces a distinctive mottled, color-case appearance with warm brown and blue tones, giving the pins a classic, premium look often associated with high-end firearms. Black nitride (also known as Melonite or QPQ) produces a uniform matte black finish with slightly higher surface hardness. The choice is largely aesthetic — both are built to last.
Do these pins require any special tools or modifications to install?
No special tools or receiver modifications are required. The Fortis Enhanced Pin Set installs exactly like standard mil-spec takedown and pivot pins. You'll need your existing detents and detent springs (not included), which simply drop into place during standard lower parts kit assembly. No drilling, fitting, or gunsmithing is necessary for a properly spec'd mil-spec lower.
