So far I have not seen SAR-21 fitted with a suppressor yet.But
what I can say is that the earlier posting that the SAR-21 will
accept M-16 MAGs only in the Export Version.And future
considerations are made to ensure that they can be fitted with the
current proprietry magazines.This is quoted in the Guns and Weapons
fo Law Enforcement Magazine in January 2001 Pg.77.
And please note that the US and other countries which have formerly
adopted the Metal STANMAG are shfthing to the new polymer
see-through mag.And I have seen them being used in the
FAMAS,M4,M-16,G36,H&K53,Styer Aug and many other weapons.
