Frequently Asked Questions
Will these pins fit my AR-15 lower receiver?
Yes. The Fortis Takedown & Pivot Pin Set is machined to mil-spec tolerances (.247–.2485), making it compatible with the vast majority of standard mil-spec AR-15 lower receivers. If your lower accepts standard mil-spec pins — which most do — these will drop right in. Always verify your specific lower's pin hole diameter before purchasing if you're using a non-standard or proprietary receiver.
What is the advantage of a drill-through pin design?
The drill-through design removes material from the center of the pin, reducing overall weight without compromising structural integrity or rigidity. Combined with the inherent strength of 17-4 stainless steel, this means you get a pin that is both lighter than a solid stainless steel alternative and more durable than a standard mil-spec steel pin — a genuine performance upgrade with no trade-offs.
How does black nitride compare to a standard blued or phosphate finish?
Black nitride (also known as Melonite or QPQ) is a surface hardening treatment that penetrates the steel itself rather than sitting on top of it like a coating. This results in a finish that is significantly harder, more wear-resistant, and more corrosion-resistant than traditional bluing or phosphate. For small parts like takedown and pivot pins that see repeated contact and handling, nitride offers a longer-lasting, lower-maintenance finish.
