|The selective fire member of the E-11 family differs from the original E-11 by having two additional positions in the trigger group, thus allowing the E-11/F to be fired single-shot, in short bursts (3 shots) and in long bursts (10 shots).
Early test results showed that the standard barrel was too light and incapable of dealing with the extra heat produced by extended automatic fire. So, a heavy barrel assembly with an extra cooling system was designed. (This new barrel was later used with the E-11/H model.) Although it is not as widely used as other members of the E-11 family, the E-11/F is still in production and in use with the Empire, CSA and other organizations as both an individual and support weapon. The E-11/F was the inspiration behind the ES-23, which is more suitable for the heavy fire support role.
An additional trigger group that allows single shot and 6-round bursts is available at no extra cost from the manufacturer.
