AR 10 in the Dominican.

[RCS]

The AR-10 was manufactured under license by a Dutch Company in 1960 and adopted by Portugal. These were issued to paratroops and special forces and used
from 1961 to 1974 in Angola, Portuguese Guinea and Mozambigue extensively. Some were fitted with 3x scopes, all were selective fire and could use rifle grenades.
None of these AR-10's exhibited the problems and issues associated with the early M16's service in Viet Nam under identical conditions.

Note: after Portugal retired their AR-10 rifles, the parts kits (without the selective fire lower) were imported into the USA where some companies manufactured a
semi auto steel lower to fit these kits, they are still around !
