What is an AR-40 rifle?

An AR-40 rifle is an AR-style pistol caliber carbine chambered in .40 S&W. Unlike a traditional 5.56 NATO AR-15, an AR-40 is configured around the dimensions and operating requirements of the .40 S&W pistol cartridge. Moriarti AR-40 rifles combine .40 S&W chambering with AR-style controls, ergonomics, and modularity, with individual models varying by barrel, handguard, furniture, finish, magazine compatibility, and other specifications.
