A look at the new .264 Round from FN and the Rifle that Uses it
FN America brought some of the best new tech to SHOT Show last month, including a new weapon system developed for the “Irregular Warfare Technology Support Directorate.”
Built around a new 6.5x43mm Lightweight Intermediate Caliber Cartridge, or LICC (lick?), that the company says delivers 7.62 NATO performance in a 5.56-sized package, FN’s new Individual Weapon System was developed for the IWTSD, a government office that supports the U.S. special operations community. Originally formed in 1999 as the Combating Terrorism Technical Support Office, for those curious, the “IWTSD Identifies and develops capabilities for DOD and Interagency customers to conduct Irregular Warfare against all adversaries, including Great Power competitors and non-state actors.”
The 6.5x43mm was developed by the U.S. Army Marksmanship Unit in partnership with IWTSD and was originally dubbed the .264 USA back in 2014 while the LICC designation was in use by 2016. Awarded a contract in 2019 to further develop the concept and a weapon platform to use it, FN delivered prototyped 6.5x43mm Individual Weapon Systems to the government for testing last summer.

FN optimized the round for practical use and had examples on hand at SHOT Show, seen here with 103-grain bullets loaded. Would be interesting to do the math on that ballistic coefficient. (Photo: Chris Eger/Guns.com)
