How to Know What Your Used Firearm Is Worth

The used gun market is a fast-moving one, constantly shaped by supply, demand, and perception. But you have to keep up with it if you’re selling a gun and want to get your money’s worth.

Whether you’re a private seller or a veteran clearing out your safe, that means knowing your firearm’s current value.

It’s not about what you paid for it originally, in most cases. It’s not even about blue book numbers. It’s about what people are paying for it (or guns like it) now.

In this guide, we’ll break down what matters when valuing your gun. This can help you avoid leaving money on the table, especially if you’re trying to sell guns online.

Condition Is King

In most cases, the main influence on resale value is the firearm’s condition. Guns are typically rated on a scale from “New in Box (NIB)” to “Poor” or “Parts Only.”

Look for wear on moving parts, barrel pitting, or fading bluing. Every wear or handling mark drops value. The same goes for function issues.

The National Rifle Association (NRA) and Blue Book of Gun Values both offer condition grading guides. While helpful, they’re just the starting point. Buyers will judge for themselves.

Is Your Gun In-Demand?

Like classic cars, some guns just hold value better. Pre-ban Colt AR-15s and M1 Garands are examples. There’s always a market for them.

If your firearm is a discontinued model, limited edition, or part of a collectible series, that may boost its value too. Research similar completed sales to check.

Recent auction results are a good litmus test. Remember to look only for successful auctions, however.

Listing prices don’t count, as anyone can list a beat up Glock 17 for $10,000. That doesn’t mean anyone will ever buy that gun for $10,000.

Be aware too that most successful options will yield optimal pricing. That may be hard to get if you’re not a professional auctioneer or have their marketing and networking resources for sale.

Accessories Can Add—but Only a Little

Scopes, lasers, or aftermarket triggers won’t return full value. Most buyers consider accessories a bonus, not a price multiplier.

The usual rule is to expect only 20% to 50% of their original value in resale… and that’s only if they’re in very good condition, plus from popular brands.

If your accessory is a high-value one like $300 optic, consider selling it separately instead. It’s usually best to sell those apart from the gun.

As for original boxes and manuals, they’re more likely to add appeal if they’re for collectible or antique guns. They’re less valuable for modern, mass-produced models.

Regional Laws Affect Pricing

Gun laws vary dramatically by state—and that affects price. A California-legal AR with a fixed magazine often costs more in California than in a state with looser gun laws.

Likewise, handguns on restricted rosters (like in Massachusetts or California) may carry added value due to limited availability if you’re in those states. Know your laws before you list!

Better yet, ensure any buyer understands the legal process. For those who prefer simplicity, platforms that help you sell guns online legally and efficiently can save time and reduce liability.

The Market Moves Fast

Used gun values can shift month to month. Political events, crime waves, and proposed legislation all stir demand.

After the 2020 pandemic began, background checks in the U.S. hit record highs, with over 21 million checks conducted that year, per FBI data. That drove up demand (and value!) especially for common calibers and carry pistols.

In 2025, while the market has normalized, high-quality used firearms still fetch strong prices. Inflation-resistant goods like guns tend to hold value better than electronics or vehicles.

Where You Sell Matters

Listing your firearm locally may limit your reach, which can limit your gun’s value. Gun shows, forums, and auction platforms widen your audience but come with their own complications.

Face-to-face transactions require vetting. Online sales often need an FFL (Federal Firearms License) holder to facilitate the transfer and cover the legal requirements.

If you want to avoid haggling or mistakes, consider working with a licensed gun buyer like Cash for Arms. The company specializes in buying used firearms from private owners for high prices. You get full legal compliance and free gun appraisals as well.

Final Thoughts

Finding your used gun’s value is part research, part realism. There are so many factors that can cause your gun’s worth to shift up or down.

Take the time to grade your firearm, understand the market, and choose the right path to sell. Whether you’re trimming a collection or liquidating an estate, knowledge keeps you in control.

The right buyer will see the value in what you own, of course. But it’s up to you to know it first.
