Been having a lot of fun with L85 muzzle brake / angled grip lately. Don't see enough of a difference in hip fire to use ergo, and bursting really negates the gains from stubby. Probably going to end up switching to the ACE full time though, the L85 is just wonky at times.
For those of you who don't know about the booby traps on Op Lock; there are 4 traps located across the map, which, upon accessing them, coat the area in flames (think of it as a highly improved incendiary grenade, that actually works).
You activate them by shooting the red pipes where the steam/gas is spraying out. Takes ~2 bullets. Cooldown is ~10 seconds
Locations:
E flag, second floor, right after you come in from outside.
E flag, on the right if you're leaving spawn, in the kitchen/whatever that room is (I think? I'll double check later, this is the one that has the least usefulness)
B flag, in the kitchen.
B flag, behind the kitchen in the hallway. Right near the top of the stairs leading to lower C.
It's hilarious roasting multiple enemies to death when they make a push at said areas. Good area of denial tactic, especially if you're low on ammo.
