The IMBEL IA2 is an all-modern, locally designed, developed, and produced assault rifle originating from Brazil. The series was adopted by the various services of the Brazilian Armed Forces to overtake an aging, mixed collection of the Brazilian IMBEL MD97, Belgian FN FAL, American M16A2, and German HK33 automatic rifles. The MD97 itself was a localized offshoot of the classic Cold War-era FN FAL (detailed elsewhere on this site) and taken into service in 1997 in the intermediate-power 5.56x45mm NATO chambering. The IA2 brings about more modern features as well as design flexibility, leading to a modular, robust assault weapon solution.

The IA2 is currently known in two chamberings, 5.56x45mm NATO and 7.62x51mm NATO, and these form the basis for several rifle types including the base, full-length IA2 rifle, a shortened assault carbine form, a dedicated, compact Close Quarters Battle (CQB) model, a full-length / full-power Battle Rifle model, and a dedicated Sniper / Designated Marksman Rifle (DMR) variant. The rifle, carbine, and CQB models are all chambered in 5.56mm while the Battle and sniper / DMR models support the ubiquitous, full-powered 7.62mm round.

The rifle's general arrangement remains conventional as modern rifles go: At the rear is an adjustable shoulder stock. The pistol grip / trigger unit is slung under the frame in the usual way with the grip given an ergonomic slant. The trigger loop is oversized to take on a gloved hand and the magazine well is positioned just ahead. The charging handle sits to the left side of the body along with fire control functions located within reach of the primary hand's thumb. The firing controls are doubled along the right side, making them ambidextrous, to support both right- and left-handed shooters without modification. The ejection port is positioned along the right side of the frame with an M16-style deflection block being prominent here. The muzzle also has an M16-style multi-slotted appearance to aid in recoil.

Weight of the unloaded weapon is 7.1lb with an overall length reaching 39.1 inches and barrel assembly measuring 17.2 inches long.

The long-running section of Picatinny rail over the receiver and forend allows a plethora of sighting devices - including a broad array of optics, magnifiers, and aimers - to be used. Additionally, shorter sections of rail are located close to the muzzle for additional mounting points - these mounting points useful for laser sights / aimers, tactical flashlights, and even an Under-Barrel Grenade Launcher (UBGL) suppression component. Iron sights are retained for backup purposes.

Internally, the gun relies on the proven gas-operated, rotating-bolt arrangement seen in many other automatic rifles the world over. Rate-of- fire reaches up to 750 rounds-per-minute (model and chambering dependent) and muzzle velocity is rated at 3,000 feet-per-second (again, model and chambering dependent). The rifle feeds from a 30-round STANAG-type magazine when in 5.56mm chambering and the 20-round FN FAL style magazine when in 7.62mm.

The original project that led to the IA2 initially looked to modernize the MD97 design (as the "MD97 Mk.II") but this led to an overall extensive reworking of the entire approach - resulting in a whole new rifle better suited to modern battlefield requirements and abuses. An initial modest order for 1,500 IA2 rifles was placed in 2012 by the Brazilian Army which led to extensive evaluation by multiple Brazilian military elements. The rifle was then cleared for service - leading to the Army securing an order in December 2013 for 20,000 examples, these to be chambered in 5.56x45mm NATO.

A chief operator of this rifle is Brazil's Special Operations Brigade and the system also serves with special paratrooper elements as well as jungle troops and Marines.©MilitaryFactory.com
