The ED24 series is a versatile gun. It is able to adapt into many variants, including (not limited to,) ED24BR, and the ED24LMG.
The ED24C is in use of these countries.
The jack of all trades. Better suited for CQC, coming with a 30rd magazine.
The ED24BR is suited more for long ranges, due to the longer barrel, at the cost of a smaller, 20rd magazine.
The ED24LMG is good at enemy supression. It comes with a standard 60 round drum magazine and a bipod for fortified engagement.
