M10 Breacher Shotgun
I would've called it a KRM Breacher, personally.
M10 Breacher Pump Action Shotgun
I was a bit of a hater for this gun's charge up trigger. Now, I'm okay with it. What I thought was a delay caused in the charge trigger was actually a delay in sprint out time, because gungho doesn't affect sprint out time.
I was also nervous trying to match the ammo counter of the game with the port here for H3, but I'm happy to say I fucking NAILED the ammo counter with a psuedo 3D effect selling the look immensely. No need for all that extra crap, it's perfect.
The opt-in for magazines was a nice touch, and I do think they cooked in making this shotgun stand with the likes of the Mog-12 and KRM-262. Its a fun pump shotgun, no matter if its BO7 or H3!
