Which is why an AR-15 with ACOG is better than a suppressed H&K MP-5 for that reason.

Er...well...I can't speak for all of them. I work for a large state “agency” and have some overlap with LEOs. A good many of the SRTs here either use M-4 (clones), or the H&K UMP chambered for the .45ACP. The H&Ks are suppressed. I haven't seen a suppressed M-4 yet, but that doesn't mean they don't have them in the inventory. They tend to like the Eotech sights. They're half the price of ACOGS.
