Heat transfer - heat from firing heats the barrel, the first six inches of which is in direct contact with the uppermost rail, which heats up excessively. Why excessively? Optics fitted during trial - that had no issues when fitted to other rifles - were damaged by the heat. If its not heat transfer, please provide the correct terminology.
I said lights and lasers. Youre right, I should have specified, the PEQ-16. The rail is so far rearward that there is a rail extension sub system being developed to fit the light (as a separate system) farther forward.
Have you ever used a rifle while wearing body armour? Worn different body armour types over the life of the rifle? Or watched the 152cm tall female soldier, wearing body armour, trying to qualify during an advanced shoot, struggle with a fixed LOP? The EF88 doesnt have a forward grip integral.
The EF88 Is rubbish. They took an AUG, already borderline for the second decade of this century, and designed out all the good bits.
