Given the overall optic ruggedness and long battery life with modern red dots, holographic, and scopes, what is the opinion on running no iron sights versus folding sights versus fixed front / folding rear for a fighting / training carbine?
Funny, but I was having this same discussion at the DFW Gun Show this past weekend. If running military grade optics (e.g., Trijicon) BUIS just seem like a useless addition. I have never had an optic fail yet (Aimpoint, EoTech, Trijicon, etc.) and don't expect to see combat, so as I acquire new platforms, I am just going to run the optic and forget about the BUIS. As I age, I find the BUIS become less and less useful anyway.
Yeah, as a general thing, I don’t use iron sights either because my eyesight was degrading for a long time until I had my cataract surgery. But as a matter of policy, I always put irons on my rifles if they didn’t come with them. I have one rifle that doesn’t have iron sights, and that is my Remington 700. Most of the rest have an optic too, but having iron sights is just part of prepping for me. An RDS without a battery is just a piece of glass to look through. As much as I like my T2 Micro as an RDS, it’s useless if the battery goes down. That’s why the T2 is the only optic I own that doesn’t have an etched reticle. That’s why I love ACOG type optics over an RDS.
Makes sense - agreed it is hard to beat ACOG if money is not a factor. Thank you for your thoughtful response.

My el Cheapo PSA rifle has “fixed” iron sights (regular gas block front sight, rail-mounted A2 style rear sight without carry handle) 1/3 co-witnessed through a Sig Romeo5 red dot. I was a die hard iron sight guy—I did BRM back when men were men, before the Army stopped teaching recruits how to shoot and started letting them qualify with Aimpoints and ACOGs. Sure, I shot other guys red dots, but for years wouldn’t be caught dead spending my own hard earned money on such an unnecessary extravagance as an Aimpoint or EOTech.

Then, not long ago, I saw the Romeo5 on sale, and decided to give it a try on el Cheapo. It’s great for the price: 2 MOA dot and it holds its zero like a champ. Boringly easy at 100 yards, though I prefer irons a bit at 200 or 300.

It’s all personal choice. Scopes are great for some, but I can’t stand them on an AR. I shoot better with a red dot or irons than with a scope out to 300 yards, and 5.56 from a 16” barrel is of little use beyond that. Others probably prefer scopes at a much closer range. I think part of it is I didn’t hunt as a kid and grew up shooting with iron sights.

We have similar experiences ... and I am rethinking the iron sight ideology given modern optics advancements, coupled with my failing eyesight due to aging. Thank you for sharing your insights - very much appreciated.

On my M4, when I had a 1x EoTech I had the rear iron sight on. I’m not sure why other than I light forget to turn on the dot or the battery could go dead. However, after switching the EoTech out for an ACOG I ditched the iron sight.
Makes sense. USMC made the decision recently to dump fixed iron sights due to ACOG reliability, but still kept folding BUIS - presumably for old school marksmanship training and not necessarily to backup an optic that is 99.99%+ reliable.

Thank you for taking the time to respond to my question.

You can't co-witness iron sights with a scope. Not even 1x so irons do no good with a scope unless you take the scope off or mount them 45 deg offset.

You can co-witness thru a red dot. I run MagPul BUIS (backup iron sights) on my backpack AR pistol with a AimPoint Pro red dot.

Fixed front sight with above 1 or 2 power you wont see it in the scope. At least on mine at 4x (lowest power) you don't. It looks like it should block your view but it doesn't.

You just need to decide if you think you need the backup sights or not. If it's for self defense, I think it would be wise.
All good points - thank you for taking the time to respond.

Military SF acquaintances tell me they have not used BUIS ever in the past 15 years of direct action experience. I am old school - and that may be part of the problem - but am beginning to equate iron sights and modern optics with engineering tools: when 3D CAD was in its infancy, engineering was still 2D. For the past 20 years, 3D CAD stands alone. Nobody keeps a T-square and drafting board as a backup anymore for if the software fails.
