Brazil took delivery of a small quantity of FN-made FAL rifles for evaluation as early as 1954.
Troop field testing was performed with FN made FALs between 1958 and 1962.
Then, in 1964, Brazil officially adopted the rifle, designating the rifle M964 for 1964.
Licensed production started shortly thereafter at the Indústria de Material Bélico do Brasil (IMBEL), in Itajubá in the state of Minas Gerais.
The folding stock version was designated M964A1.
By the late 1980s/early 1990s, IMBEL had manufactured some 200,000 M964 rifles.
Later Brazilian made FALs have Type 3, hammer forged receivers.
Early FN made FALs for Brazil are typical FN 1964 models with Type 1 or Type 2 receivers, plastic stock, handguard, and pistol grip, 22 mm cylindrical flash hider for grenade launching, and plastic model "D" carrying handle.
Brazilian-made FALs are thought to have been exported to Uruguay.
A heavy barrel version, known as the FAP (Fuzil Automático Pesado, or heavy automatic rifle) was also produced for the armed forces, to be used as a squad automatic weapon.

Brazil's planned service weapon was a development of the FAL in 5.56×45mm.
Known as the MD-2 and MD-3 assault rifles, it was also manufactured by IMBEL.
The first prototype, the MD-1, came out around 1983.
In 1985, the MD-2 was presented and adopted by the Military Police.
Its new 5.56×45mm NATO chambering aside, the MD-2/MD-3 is still very similar to the FAL and externally resembles it, changes include a change in the locking system, which was replaced by an M16-type rotating bolt.
The MD-2 and MD-3 use STANAG magazines, but have different buttstocks.
The MD-2 features an FN 50.63 'para' side-folding stock, while the MD-3 uses the same fixed polymer stock of the standard FAL.

However, Brazil's current service weapon is a Brazilian FAL-based assault rifle in 5.56×45mm and 7.62×51mm versions, with Assault Rifle and Carbine variants, including a Sniper and CQB rifle, called the IA2, also produced by IMBEL.

Along with the IA2, MD-2 and MD-3 assault rifles, Brazil produces the M964A1/Pelopes (Special Operations Platoon), with an 11" barrel, 3-point sling and a Picatinny rail with a tactical flashlight and sight.

Brazilian Army officially used the FAP (Fuzil Automático Pesado, or heavy automatic rifle) as its squad automatic weapon until 2013/2014, when the FN Minimi was adopted to replace it.
The Marine Corps and Air Force also adopted the Minimi to replace the FAP.

IMBEL also produced a semi-automatic version of the FAL for Springfield Armory, Inc. (not to be confused with the US military Springfield Armory), which was marketed in the US as the SAR-48 (standard model) and SAR-4800 (made after 1989 with some military features removed to comply with new legislation), starting in the mid-1980s.
IMBEL-made receivers have been much in demand among American gunsmiths building FALs from "parts kits."

IMBEL in 2014 offered the FAL in 9 versions:
M964, the standard length semi-auto and full auto.

M964 MD1, short barrel semi-auto and full auto.

M964 MD2, standard length semi-auto only.

M964 MD3, short barrel semi-auto only.

M964A1, folding stock standard barrel semi-auto and full auto.

M964A1 MD1, folding stock short barrel semi-auto and full auto.

M964A1 MD2, folding stock standard barrel semi-auto only.

M964A1 MD3, folding stock short barrel semi-auto only.

M964A1/Pelopes, short barrel semi-auto and full auto with Picatinny rail.

Currently, Brazilian Army and Marine Corps Groups still use the FAL as their main rifle, as many troops are not yet issued the IA2.
