El Salvador is the latest country to add the ACE to its arsenal. With its new IWI Galil Ace, Israel is fast becoming the premier AK vendor.
This is just wild speculation, but I wonder if South Africa is taking a look at the ACE. They licensed the Galil ARM and SAR back in the 80s and developed the R4 Assault Rifle. The R4 (or its carbine brethren the R5 and R6) and looking a little dated after 30 years.
