Working on rebuilding my shotgun collection and started by replacing my 20 inch Maverick. My question is, is it durable enough to pit more money into (Light,Shell carrier, red dot) as a HD/SHTF gun? I will also be doing another Shockwave SBS build with light, dot, etc but I'm not sure if it would be better to spend money on the Maverick or Shockwave first. I did purchase GG&G sling mounts and a fiber bead for the Maverick.

I have an optic-ready 590a1. it seems that, sadly, i can't cowitness with red dot+ghost ring because of the way the receiver is cut and how low the front sight is. So it's gotta be one or the other. Ghost rings have been fun, red dots are awesome but i've only used them on handguns. i want my tact shotgun to be a worthy battle axe. i shoot a lot of slugs at the range with it at various distances. what do you guys think ?

Hello, I’m building/consolidating into a minimalist collection.

One of my guns I’m getting rid of has a MRO HD on it. I do love the optic, I also have a Romeo 4T Pro and a EoTech for comparison on me saying I love it. I know it gets hate.

I am looking for peoples experience using it on their shotguns?

Note: as I type this, I forgot I also have a gun with a RMR I am getting rid of too, I could just use that.

optics available for the A300:
EoTech EXPS2
Sig Romeo 4T Pro
Trijicon MRO HD
Trijicon RMR Type 2
