I love the practicality in this. it's a little speedy so you can re-position and you don't have to expose much when peeking. Edit: how does the heat fair in the STD/HS version?
I don't own it so all I can do is speculate. I think that on a map like Rubellite it will still get hot even with just 1ERML, but with more HGR ammo, you can use your shots less sparingly, so it should be sort of similar to DHS, which cools faster than you need it to.
