SAR-21

The SAR-21 (Singapore Assault Rifle - 21 Century) is a bullpup assault rifle designed and manufactured in Singapore. First revealed and subsequently adopted by the Singapore Armed Forces (SAF) in 1999, it was designed and developed over a four-year period and was intended to replace the locally license-built M16S1 by the Singaporean Ministry of Defence (MINDEF), Singapore Army and the Chartered Industries of Singapore (CIS, now ST Kinetics). Many of its design features are directly intended to counter the weaknesses of the M16S1 as encountered operationally by some infantrymen.

It makes its debut in Battlefield 4, first seen in the Battlefield 4: Battlelog Trailer.
