Question on BUIS

[Waylander]

Uh oh, something else Mark has added to his shit list?!

[markm]

Dang... I've not heard of much of that occurring with Sig Rom 5s. Heck. I love mine.

Odd too. The guys I was shooting with seemed to know that's how the battery goes. Pappabear had a spare handy and it was right back up.

Nah. If I buy something like a Romeo, I have no delusions that it is going to be as good as an Aimpoint. Now when those damned Aimpoint PROs and CTOs come out with dead batteries, that's annoying. At least, however, the Aimpoints will give you a last bit of life so you know you need a battery.

The only time I use mine is checking zero with whatever ammo, never actually needed them, but they will always be there. Essential kit for me.

Also.. a good way to check that the dot hasn't lost zero. Reconcile it to the irons, and you don't have to shoot it to confirm.

There are a lot of people (including trainers) who use an alternate back-up (maybe a smaller red dot) vice irons.

Many who choose not to use a back-up at all are not in the real-world gunfight business where the risk of an electro-optic failing means somebody (not the bad guy) could be shot, crippled, or killed.

Not an actuary or statistician, but there's always risk (which equals likelihood x consequences) -- why, over time, things like seatbelts, airbags, helmets, insurance, reserve parachutes, IFAKs and tourniquets, and/or a handgun might be considered prudent backstops. You don't need any of them -- but when you do you need it now.

I'm not in the real world gunfighting business, and hope I never have to be, but.....

Modern optics are very reliable. That being said they do still fail. I drove to my uncles ranch in Oklahoma to do some hog hunting. My TA31 ACOG died during the smooth highway drive there. Sitting in a padded hard case too. Luckily the back up irons on the gun still worked.

On a more serious note, a dude in my company had his Aimpoint shot off his M16 in 2005. He flipped up his irons and continued the fight.

I might use an RDS to backup a magnified optic on a range only gun, but anything intended for off-range use will have BUIS. I think I only have one AR that doesn't have BUIS and it hasn't even been to the range yet.

I still have standing irons in front and back of my red dot. Non folding. They aren't in the same plane of focus as the red dot and don't interfere with the red dot sight picture, I never even think about taking them off. They're just there when or if I need them.

[HKGuns]

I used to put folding back up Iron sights on everything. But you reach a point of accumulation where that no longer makes a lot of sense.

Around two years ago I switched from putting them on everything to as follows:

Scoped rifles - Scope only, no irons
RDS / EOTech - Optic and Irons

Then of course I have rifles with irons only and those that come with iron sights standard with some sort of optic added. EX: HK91 with claw mounted Hendsoldt Fero Z or MP5 with an RDS.

My oddest combination is the Tavor, it has an LPVO with a small RDS on top of the scope. It also has the built in folding irons as well.
