The IA2 assault rifle, designed and built in Brazil by IMBEL, is designed to replace the FAL, M16A2 and HK33 currently in service with the Brazilian Armed Forces.


The IA2 comes in 2 calibers: 5.56×45mm NATO and 7.62×51mm NATO. It should be noted that it is not modular like Colt CM901, Remington ACR, CZ 805, or Beretta ARX-160.[citation needed] The 7.62 NATO variant still uses the FAL operating system (tilting breechblock) versus the 5.56's rotating bolt. The IA2 makes extensive use of polymers, and features a non-reciprocating cocking handle on the left side of the receiver. The 5.56 variant accepts an M16 compatible STANAG magazine, while the 7.62 accepts FAL magazines. The IA2's gas system is manually adjustable.[1]


Thanks to integrated Picatinny rails the IA2 supports a wide range of equipment and accessories such as scopes, flashlights, grenade launchers, lasers, etc.
