I know... sacrilege.
I'm looking for recommendations on an AR style shotgun. I see that nowadays there are oodles to choose from and I'm not quite sure what's good and what's garbage. basically what I'm looking for.
1. flat top upper (accepts standard AR 15 iron sights and/or red dot)
2. 3 1/2 in. chamber would be awesome but would be willing to settle for a 3 in.
3. multiple barrels would be nice (rifled and choked so you can switch between slugs and shot) but not a deal breaker
4. commonly available, replaceable, chokes are a must.
5. fully detached pistol grip and stock (I've tried the ones with the connected, faux thumbhole stock, I think they're called vipers and they're awful.
6. an adjustable stock would be nice, but not a deal breaker but I am a very large person and require a long length of pull.
7. even better if it accepts actual AR furniture, but understandable if it doesn't
TIA
