How Much Is a Heckler and Koch HK91 Worth? (2026 Value Update)

How We Calculate Used Heckler & Koch HK91 Values

The value of your HK91 is influenced by its condition, specific variant and caliber, and included accessories.

Condition and Values

Preserving your HK91’s condition directly affects resale value. Proper maintenance helps achieve the best possible offer for your rifle and makes selling easier.

You can go to a local gun shop for an in-store appraisal, though most of them charge a fee. If you’re looking to sell your gun you can request a free gun appraisal from us for a quick valuation.

To see how we professionally evaluate your firearm (for free) and turn that condition into a payout, view our 3-step selling process for a guaranteed FFL offer.

How We Appraise HK91 Models

The HK91 lineup includes a few notable variants. Identifying your specific version, configuration, and markings is essential before selling.

Heckler & Koch HK91 (Standard) Value

The average used HK91 is worth $2,000 to $4,000.

The civilian semiautomatic version of the G3 rifle, the HK91 features a roller-delayed blowback system and 7.62×51mm NATO chambering with a 20-round detachable box magazine.

HK91 A2 (Fixed Stock) Value

The average used HK91 A2 is worth $2,000 to $4,000.

This model uses a solid polymer fixed stock and classic slim handguard, offering excellent stability and recoil control.

HK91 A3 (Collapsible Stock) Value

The average used HK91 A3 is worth $2,100 to $4,100.

Equipped with a retractable stock, the A3 variant is lighter and more compact, making it desirable among collectors and shooters seeking portability.

HK91 with PSG-1 Trigger Group Value

The average used HK91 with PSG-1 components is worth $2,500 to $4,500.

Rifles upgraded with PSG-1 trigger assemblies or furniture fetch premium prices for their enhanced precision and match-style ergonomics.

This is a model that holds value well. Because it’s a premium firearm in the line, we use a secure gun shipping and buying system to ensure every transaction is fully insured and legally compliant.

HK91 PTR-91 (Licensed Clone) Value

The average used PTR-91 is worth $550 to $1,100. A new PTR-91 sells for around $1,699 at retail.

Produced in the U.S. using HK-licensed tooling, the PTR-91 closely replicates the HK91’s design and operation, offering excellent performance and modern availability at a lower price.

HK91 SAR-3 Value (Licensed Clone)

The average used SAR-3 is worth $800 to $2,105.

The SAR-3 was an early Greek-made licensed copy of the HK91, known for solid build quality but lighter collector interest than original German models.

HK91 FMP Value (Portuguese Licensed Clone)

The average used FMP HK91 is worth $480 to $820.

Manufactured in Portugal under HK supervision, the FMP rifles are licensed builds that offer authentic HK performance with slightly less collector premium.

How Accessories Affect What We Pay for Your HK91

Accessories can influence the HK91’s resale value when they’re quality aftermarket components.  Lower-quality ones barely provide extra value.

If you’re looking for a buyer for your full setup, try contacting us. We buy HK rifles with accessories and extra magazines included often.

Original Box and Papers

Having the original HK case, owner’s manual, and documentation shows the rifle has been properly cared for and verifies authenticity.

Value: Around $25 to $50 for matching case and documentation.

Optics and Sights

Scopes or claw mounts from reputable brands increase buyer interest and can add to overall value.

Value: Around 30% to 50% of the accessory's retail value.

Extra Magazines

Factory HK steel or alloy magazines are more desirable than aftermarket ones, and including them can boost your offer.

Value: Around $15 to $35 per additional factory magazine.
