Yesterday I saw 7 pulse rifles and about 8 snipers. Also saw about a dozen armor pieces in about four hours.
I've seen a lot of (mostly) nothing. Obviously lol. And lots of reports of the same from tons of people. And like, I said, I'm not just talking about MY rewards, but the entire team(s). The word "random" in "random number generator" excludes that kind of consistency by its very nature.
It started poor for me. But got better. Got the pulse rifle Got the sniper twice. Legs a couple time and arms a couple times. Turned out to be pretty decent.
