Have an HK416
I bought it for fun and didn’t have too high of expectations. I handled and shot a buddies SW and was not overly impressed so I wanted to go a different route.
Biggest drawback to his SW was unreliable feeding and ejection.
The HK does not have a great trigger but definitely feels a bit more solid in the hands. And I have run that thing to filthy and back and it simply will not fail.
It chews up and spits out anything I feed it
