Notes: This weapon, based on the Mauser M-1898 action, is virtually identical to the Spanish Mauser M-1893, except for a cylindrical bolt-head, and a rounded magazine-follower head (so that the bolt could be shut on an empty chamber after the magazine was empty). The M-1894 was chambered for the 7mm Mauser round, and fired it from a 29-inch barrel. The rear sight is adjustable from 400-2000 meters.

The M-1894 Carbine was similar, but was much smaller with a much shorter 18-inch barrel. In addition, the carbine had a sight graduated for shorter ranges, a straight bolt handle, and there was no bayonet lug. The M-1904 (also called the Mauser-Verueiro 1904 rifle) is a further modification of the Itajuba-built Mauser M-1894, with a pistol-grip stock, a slightly-shorter barrel, and slightly lighter weight; it was also chambered for the 6.5mm Portuguese cartridge instead of 7mm Mauser. The M-1907 rifle (the M-1907 rifle is often mis-identified as the M-1908 due to a very similar appearance) and carbine were based on a later version of the M-1898, but for game purposes, are identical to the M-1894 rifle and carbine – except that the M-1907 carbine can accept the same bayonet as the M-1894 and M-1907 rifles. The M-1908 rifle is, as noted above, very similar to the M-1907 rifle, but the barrel is a little longer at 29.25 inches and the bayonet used with the M-1908 is the German H-type bayonet with a muzzle ring. The M-1908 Short Rifle is, as the name suggests, a shorter version of the M-1908 rifle; it had a 22.05-inch barrel and a turned-down bolt handle. The M-1922 Short Rifle is very similar, but Brazil bought them from FN, and they used a straight-wrist stock instead of a pistol grip-wrist; they are considerably lighter than M-1908s. The M-1924 Short Rifle was a Czech version that (for game purposes) is identical to the M-1908 Short Rifle; these rifles were originally ordered by Brazilian insurgents in 1931, but were quickly captured (along with the insurgents) and put to use by the Brazilian Army. When Czechoslovakia was overrun by the Nazis in 1939, production began in Brazil without a license.

The M-1935 rifle was essentially the same as the M-1908 rifle, but built on the newer Kar-98b platform with its tangent rear sight. Unlike its German equivalent, the M-1935 had a straight bolt handle; like the German versions, the M-1935 was chambered for 8mm Mauser. The M-1935 Short Rifle was the same rifle with a shorter 22.05-inch barrel; it also used a turned-down bolt handle.

After World War 2, many of Brazil’s Mauser-type rifles and short rifles were re-chambered for the .30-06 Springfield cartridge. The rifles also had their barrels shortened, so that all of them were essentially short rifles. This also necessitated a re-tooling of the sights, and at the same time the bayonet lugs were changed to accept the same bayonet as used on the US M-1 Garand rifle. The bolt handles, if straight, were also turned down. Stocks were also often remade using South American hardwood instead of the European wood used before. The two rifles so produced were the M-1908/34, with a 23.6-inch barrel, and the M-1954, which had the addition of a rifle grenade launcher attachment at the muzzle. The M-1954 is otherwise identical to the M-1908/34 for game purposes.
