In 2019 - It's okay to not have BUIS on your defensive AR

[DocGKR]

Every time I went on duty, I flipped up the BUIS and confirmed that my RDS had not had a dot shift. That is a significant reason to have a BUIS, not to mention the inevitable Murphy induced electronic failure. My hard use pistol had an RDS, BUIS, and a green laser......

So, what do all you LPVO super studs do for back up sights?

I'm no expert, but it seems to me that there are a couple of different options out there - you could go with either irons or a mini red dot on a 45-degree offset mount, or use one of those scope mounts that has a little bit of rail on top of the scope and put a mini red dot up there. Flip up irons and putting the LPVO on a quick detach mount could work, too. I think the fastest/most reliable to transition to in the event of a sudden failure would probably be the 45-degree offset irons, but if circumstances dictated that you had to use them for an extended period, that might not be great from an ergonomic perspective. Again, I'm no expert, so these ideas are worth what you paid for them.

No super stud here. I’m just a regular stud. By I run 45 degree offset BUIS. I’ve also run a 45 degree MRDS.

^ This is why I have a BUIS on my red dot rifles, to verify dot zero ^
On my ACOG and Elcan topped rifles I don't use BUIS.

In my experience, all of the “switched on” guys made sure they had BUIS on their rifles because they were terrified of being “that guy”.

However, I’d say 87% of those same switched on studs couldn’t be bothered to actually zero them.

Want to hear a large group of grown men cry and whine like 14 year old girls? Make a surprise announcement that their optics are all dead for the next four drills.



That there’s a no-shitter.

Now you're just being a meanie.

I work with 14yo girls on the daily. Want to make a room full of 14yo cry and whine? Take away their telephones.

You know the Comanches would turn over their captives to the women to be tortured. You want to know why? You're about to find out.

I prefer having BUIS. I prefer having a full size spare tire in my vehicle as well. My "varmint" AR does not have BUIS. If the scope breaks, it would be annoying, but the consequence is just a hike back to the Jeep for the back-up rifle. A fighting rifle is a different story.

That's surprising to me.

We have to qual with both irons and optics at each in-service.

I guess this is what we're doing now, faux-controversial troll posts?

Only thing I have to add is that just like Jay mentions, a lot of BUIS aren't actually zero'd. The flip side of that is not a lot of people have actually tried shooting with just the tube/window of their optic to see what they are actually capable of. if your use-case is interior residential structure distances you'd probably be shocked at how well you can do with the dot turned off and no BUIS at all.
