thoughts and opinions on these two options? i have my carbine set up with fixed non folding irons in case my optic goes down and is my shtf option. my reasoning is if the optic goes down i can immediately transition to my irons without having to flip them up and the one piece construction seems to be more durable imo. appreciate any opinions/insight on this.

I run fixed front (DD), with folding rear (matech).

To be honest I don’t think there is any application where I as a civilian will need to resort to BUIS, but I still like having them. If you want absolute durability with folding irons get a pair of KAC irons. They are rock solid.
However my Scalarworks look cool as fuck so I just run those.

I dont care for fixed rear. Just dont like them in my sight picture. That being said, sometimes I flip up my rear sights and shoot my red dot out to distance while looking through my small peep because I have astigmatism. Fixed fronts dont bother me as much, but I think fixed rears are annoying to have in my sight picture, even on a lower 1/3. Personally, I think always having your BUIS always up and ready to go in case your optic goes down is a pretty niche requirement. Even the army and marine corps doesnt do that and they do real operator shit
Edit: I want to add, because sometimes things get lost in translation over the internet. I’m not telling you what to do, or criticizing your decision. You asked for opinions and that’s just mine

So tbf the only reason I don’t have irons is my handguard is too short (screws touch the gas tube/ gas block), but an ACOG + offset RDS kinda make BUIS superfluous.

DD fixed front. folding rear, currently trying out this https://www.amazon.com/dp/B07KBDYNGF/ref=cm_sw_r_cp_apa_glt_fabc_XWTFCDZQ8YHXNVWYVEFA?_encoding=UTF8&psc=1
optic is eotech xps2 on a 11.5. this is my primary home defense with a CD mini rein. if you switch the rein on my red dot disappears(depending on setting) but the fixed front is still visible.
jury is still out on the MI rear, I think I like it

Your first scenario is sorta a non-issue. You’re very unlikely to have an optic “go down” and you need to transition in a quick hurry, a lot of people go with backups because of battery or electronic concerns, not that their optic is going to get shot or bumped to lose zero (assuming it is a good optic). Good quality folding sights are great, anyway. I have Magpul-Pro front and KAC micro rear which is my favorite, but Troy ones are great as well.
If you’re asking about offset, people who have like offset fixed irons or offset red dot are generally those with magnified optics and they need to shoot closer targets.

Id say it depends on the optic, mount, and the co-witness. Mostly personal preference though.
If I had absolute co-witness I’d want both folding. For lower ⅓ Id want a fixed front and folding rear for a reference point for the optic. If I want both fixed I probably wont put an optic on since I dont like the look of fixed front sights with an optic unless the optic has a QD mount. Fixed front and rear is just too busy for me. Just my preference.
If you run a reliable red dot like a T2 I would go both folding since the T2s battery life will keep it on forever.
I run an Eotech EXPS2-0 (lower ⅓) and since it turns off after 8 or 4 hours automatically, it might not be on when I need it in a split second. If I forget to turn it on in the heat of the moment, I can use my DD fixed front sight. If it dies, I can rip it off using the QD mount and flip up my Magpul Pro rear.

High mounts and carry handle optics are my new favorite setups. I don’t know why we ever moved away from it.

Depends what you use it for. You don’t even seed sights at all if you are in close. Just point and click. You can use the lines of the handguard as a rough sight. But really, if you didn’t cheap out on your glass in the first place there’s little reason to believe it’s going to die. So why get worried about backup irons?
-
Depends on the optic. If you are running an LPVO you can’t use buis without removing the optics first. On red dots it’s user preference.

i think ill end up mounting a scope with magnification and get the offset irons, any good recommendations for the offset irons?
