Created in 1991 with and for the RAID, an elite unit of the French police, the PGM Ultima Ratio is a high-precision rifle designed for shooting at ranges of up to 1,100 yards (1,000 meters).
This legendary rifle is now used by numerous elite units around the world and is also highly appreciated by the most demanding sport shooters.
In 2022, PGM Précision introduced the second-generation Ultima Ratio, the result of more than 30 years of development and improvements based on user feedback.
Initially designed with a chassis allowing the bipod to be mounted at two positions (in front of the magazine and at the end of the handguard), the second-generation PGM Ultima Ratio has been available since 2025 with a chassis featuring an integrated Arca-Swiss rail, offering greater ergonomics and versatility.
