August 2026 GunBroker Market Takeaways

Machine Guns Dominated the Top Sales

Eleven of the twenty most expensive guns were machine guns, including transferable sears, registered submachine guns, and factory dealer samples. Fully transferable NFA firearms took the top two spots and accounted for the highest prices of the month.

Benelli’s 250th Anniversary Series Made Repeat Appearances

Three examples of the limited 50-gun Benelli Super Black Eagle 3 250th Anniversary edition placed on the list — serial numbers #4, #10, and #26 — each selling above $20,000 and confirming strong collector interest in low-serial commemoratives.

Auctions and Fixed-Price Sales Split the List

Competitive auctions produced the highest bid totals, led by the Colt M16A1 with 58 bids, while several $20,000 pieces — including the Remington M2010, Cabot America 250, and Holland & Holland side-by-side — sold as fixed-price or Buy Now listings to single buyers.

Rarity and Provenance Drove Value

Low serial numbers, pre-production examples, WWII martial provenance, and limited-run tributes repeatedly justified premium prices, from the 1979 Heckler & Koch P7 PSP to the 1908 Rigby Mauser takedown rifle.
