Point of Lower 1/3 Co-Witness

What is the point to it, or why does it exist?

I have a (fake) AN-PEQ15 that I tried putting on the top of my rail, instead of on the side, and I noticed that it blocked part of the sight picture through my Eotech.

Would that be the point to taller bases/mounts that provide a lower 1/3rd co-witness? Clearing accessories mounted in front of optics?

I use taller mounts so my x3 mag clears my rear matech bius which gives me lower 1/3 CW...

It allows the server to get more top spin on the ball making a return of the serve much more difficult. When I switched to a lower third cowitness my serve speed shot up 10mph from 130 mph to 140 mph. I really began crushing the ball, even put one straight through the net, burned a hole through it like a hot knife through buttah!!!!!

Take a breath, I'm just kidding...

It simply puts the iron sights, or your toy Peq, farther below the red dot or reticle when looking through whatever optic you're using.

You're questioning a guy who had to start a thread because he found it so unbelievable that some people actually have guns for purposes other than "toys" and tin can shooting?

Besides what has been mentioned, more of a heads up style of shooting which is a good thing and especially if you are wearing a helmet. Also good for those that prefer to run a fixed rear BUIS as it leaves the BUIS out of the field of view better for the optic.

wait......fake what?

It's so you have a bigger field of view through your optic. Instead of the front sight post and dot being centered, they are lower. When you shoot at multiple/moving targets it helps you see more without moving your head off the optic. At least for me.

Please share with us Bren, when was the last time you shot someone with your AR? When was the last time you assaulted a Taliban position with your AR, or took out a barricaded suspect with your AR?

Very few peope here use ARs for "work", most people here are civilians. No matter what most folks want to say about why they own firearms, 99.9999% of the rounds out of civilian owned ARs are for nothing more than hobby/pleasure.

The point of that thread was to show that no matter what people want to think about why they own firearms, it's mostly for fun and hobby.

And the thread showed that.

Fake/airsoft PEQ-15, I discussed it in a thread. I watched that damn movie Act of Valor, and I had to have one......so I bought a $100 airsoft version.

I'm waiting to have a spare $2500.00 lying around.

Thanks for the info.

Spend your time and money how you see fit, but don't be so quick to assume what others have their rifles for. Not everyone spends their adult life playing G.I. Joe.

So you're worried that a fake accessory compromises a sight picture? How about taking off said POS?

I do my very best not to assume anything, nor do I "play" anything. However, here in the BRF, ARs are taken very, very, very seriously by some. To the point where it's painfully obvious that a few people that post here are mall ninjas, thinking they're going to save the world with their ARs.

Being as realistic as possible, only a very few select people that post in this forum can really say that their AR is truly something they "work" with, right now, at this very point in time (and only Airborn Infantry comes to mind). Some others seem to be training and planning and building towards.....what?

At least I have the guts to lable my reasons of owning an AR based on reality, and not some self-constructed fantasy world.

How about you? Going to kick in some doors today? Going to head to Afghanistan and go on patrol?

No....not worried at all.

And it's only 1/2, or 1/3rd fake, because despite the fact that it's a cheap, Chinese airsoft knock off POS, the damn thing actually works as a normal light and laser.

Not necessary, if folks can restrain themselves from being insulting.

Interesting that you started a thread about it then....

So you're saying these are 1/2, 1/3 the quality of a real one? or at least in function? Help me out.... I'm not up to speed on Airsoft.

As far as the fake AN/PEQ-15, let's just say that's it's not completely useless. As I said, the damn thing actually works as a light & laser, which is better than I thought it would for $100.00

I get this, point still remains.... why have a toy on your rifle? Unless you can justify your 1/2 fake remark?

Is it on there to try to look cool at the range? Just curious...... otherwise your concerns here would be moot.

I am completely un-concerned about "looking cool at the range". I don't care what others think of my rifle. I like it, I like the look of it, that's all.

And as I said, it actually functions as a light & laser. So adding that to the fact that I like the look of it, I bought it. Let's call it a "functional toy".

I have no dog in this fight, however, I'm fairly certain Bren and I have been in quite a few of the same places and I'm also willing to bet he has done as much of what you stated above as any one you're likely to meet.
While it certainly doesn't matter to me, don't be surprised at negative reactions from folks. Putting a toy on a firearm does not often meet with approval from serious shooters.

So you constantly berate people here for having more serious intentions or even considerations with their rifles. Yet in the confines of your own home it makes you happy to look at your rifle, play with it, and pretend it functions like more serious use ARs? Even spending money to do so? You're saying you are considering a new Eotech to solve your problem? Yes? Just curious on the logic here.

But what would you use this function for? Home defense? Fun at the RANGE?

Please describe a "serious shooter". If someone is a serious shooter, what makes their shooting so serious? Near as I can tell, about the only serious shooters are currently in the Military, or LEOs. For everyone else, ARs are a hobby.

That's setting aside a handfull of instructors and competitors that actually earn a living shooting full time.

Why not just buy an airsoft red dot? I mean after all your AR is just a toy and the Airsoft red dot is a tube with a red dot in it.
