The SRT:
Feels like the M416 CQB when you move, so its a lighter AR.
The color is basically a Scar, which means it is not meant to be camo in most maps.
With the iTech, it has little movement when zoomed in, when shooting, I believe it jumps a bit upward (use tap for far engagement, or you can full auto for close/medium distances).
With the ACOG, it moves a bit more, but it should be standard as any other guns with ACOG, though the recoil is reduced if you set to burst mode instead of full auto.
The SRT is a 4~5 hit kills (less for light vesters and more for heavy vesters). This also means that the burst function is near useless.
It's overall bad for far range, though most people would buy this with an ACOG.
The only great thing about it is that it has as much ammo as a UMP (35), and can be expanded to 50 maximum. The reload is about the same as the M417 Combat, will be slower if you added extended mags.
My opinion: The gun is not that great.
