If you are looking to add these accessories to the Brazilian tank, which I assuming is the Trumpeter Osorio, the Kevlar is fine since Brazil uses them. They do not use M-16s though. The standard rifles of the Brazilian Army is a license-built version of the FN FAL called the M964, a folding stock Paratrooper version known as the M964A1, and a rechambered to 5.56mm version called the MD97. They look like this:
"Brazilian M964 - another license built FN FAL, one of few FAL models still in production now"
M964A1 Para
The only FN FAL that I know of in 1/35 is in the old Italeri Modern Weapons set. Sorry, I don't have any.
On another note, the Osorio was never put into service and was only experimental. The main battle tanks of Brazil are the German-built Leopard 1A1, and US M60A3. They are replacing these with the Leopard 1A5 which has been ordered and not yet fielded.
