Agreed the Matrix product was the best of that style SC upper. Too bad they infringed on Gibbz patents and had to stop making them. 7075-T6 vs 6061-T6 that most of the Gibbz style are made from. Has FA (if you like that sort of thing) and ejection port cover. Nothing coming out the back when you charge the weapon and minimum additional egress for dirt/debris to enter.
I have one on my SCR and I'm very happy with it.
