High Quality Content by WIKIPEDIA articles! The ParaFAL 7,62mm M964 A1 MD1 is a 7.62x51mm battle rifle which is a lighter-weight modification of the 30-year-old Brazilian-licensed and built FAL. Existing FALs can be converted to the more modern ParaFAL specification by the Brazilian company IMBEL with a low-cost kit of parts. Amongst the changes is a shorter barrel, and replacement of aluminium by high-impact polymer parts.
