The Triad is absolute junk, whoever came up with that gem should be pissed on and shot. It places the light/PAQ/PEQ too far forward in an exposed position,leaving them prone to damage. The CADEX fore grip/rail system is an absolute balls up, never mount a vert fore grip on the "plastic" hand guards,it allows the shooter to put too much torque on the hand guard in most cases popping the lower hand guard off of the weapon. The only solution to mounting both the aiming devices/lights and the fore grip is a dedicated rail system.
There was no need to upgrade all the C7A1 to A2, second line units have no need of them the A1 suits them just fine,if they had concentrated on the first line units the upgrade (I use the term very loosely as there was no upgrade ,just some furniture changes) could have been done much more efficiently without the soldier having to go out of pocket to correct the half assed job.
