Alexander Arms, which developed the 6.5 Grendel cartridge, has relinquished trademark protection on the round.
Why? Because the Sporting Arms and Ammunition Manufacturers' Institute, better know by its SAAMI acronym, has officially adopted the round.
"One of the primary purposes of trademarking the name was to protect the integrity of the design," Bill Alexander of Alexander Arms said in a press release. With the adoption of the 6.5 Grendel cartridge standard by SAAMI, the design is now protected, and any confusion in the marketplace as to the specification of the cartridge has been eliminated."
