Modern factory loads from American, European, and Asian manufacturers all run well in this platform, and reloaders enjoy a wide range of bullet and powder combinations.

What’s a Used Spike’s Tactical ST-15 Liberty Crusader Worth?

Private-sale ranges for a working, no-rust ST-15 Liberty Crusader in 2026 fall in four bands:

• Beater / heavily used: $350–$525 — significant wear, action functional, may need cleaning or minor service
• Average / honest used: $475–$725 — normal handling marks, mechanically sound, ready to shoot
• Excellent / lightly used: $650–$1000 — minimal wear, clean bore, original box and paperwork a plus
• New-in-box or unfired: $825–$1300 — at this price, the calculation usually flips toward buying new instead

Add a premium for documented early-production examples, original box and accessories, or limited-run variants. Subtract for refinished surfaces, aftermarket modifications a buyer would have to reverse, or signs of hard use.

The typical Spike’s Tactical buyer profile includes AR-15 enthusiasts wanting themed receivers, billet-AR collectors, builders.

Dealer trade-in offers typically run 20–30% below private-sale; if you have time to list, private sale captures the premium.
