Red dots and magnification

In a few hours I have to get on the plane, but in the meantime I found a coffeeshop and decided to check my e-mail. Naturally, I ended up doing a quick glance through a couple of forums. The ones I usually look at are SnipersHide, 24HourCampFire and OpticsTalk. Once in a while I also visit ARF, but the moderators there are sufficiently obnoxious that unless someone specifically asks me to look at a particular thread, I do not feel like dealing with the nonsense. It seems to be one of those not uncommon situations where even a little bit of power makes normal people into absolute douchebags.

This particular snippet is from 24HourCampFire. It is a primarily a hunting forum and I often find a very different take on things there. However, I do hunt and, more importantly, I plan to do a large hunting scope comparison in the not too distant future. To top it off, the gentleman who runs the forum there is a good friend, so I pay attention.

Here is an interesting post I found there: "So I bought a Burris Fast Fire 3 and put it on a camo 870 12 gauge with a 26" barrel. This was my duck gun and turkey gun ( with open beads ) now I guess it's my turkey gun, but I hate it and here's why..................I can't stand seeing the barrel and the mid bead and the front bead AND the red dot. I just want a clean sight picture of just the red dot and I imagine I would need about 1.25X to only see the bead and the turkey. Does anybody make a red dot with just enough magnification to get you out past the barrel and bead? I can't be the only one that hates the view and I won't go back to the beads as I've called in three in the last six years that got too close and I missed and around here with as few gobblers as we have that's not good. I guess the only trade off would be you would have to get your eye directly behind the dot and not have the ability to see the dot and pull the trigger even on the opposite shoulder."

He has a Burris FastFire 3 on his SpeedBead mount (https://bit.ly/3yX6je9) which allows you keep the red dot sight pretty low. That helps with cheekweld using perfectly conventional shotgun stocks. Now, personally, if I were looking at Burris red dot sights, I would easily go for the FastFire 4. I have really learned to appreciate that you can run it as an enclosed RDS and switch reticle around: https://bit.ly/3zoDWa5

That aside, the question he asks is quite important in that it shows a significant amount of ignorance of how red dot sights work. It likely comes from the fact the there used to be red dot sights with magnification, but they are essentially, reflex sights with small magnifiers built in. That sorta makes them look like prismatic scope in terms of form factor and, in the modern market, I can't think of a single reason why you would take a red dot with a built in magnifier over a normal prismatic scope.

One way to think about this is that red dot sights (and holographics) are non-focusing weapon sights. Essentially, it is supposed to be like looking through a window that somehow superimposes a dot onto whatever you are aiming at. You are not looking at a lens train that creates focal planes, etc. To have magnification, you need that lens train, but then you are dealing with the optics that essentially re-creates the image and presents it to your eye. That is very different than looking through a window at something.
Now, there are some red dot sights there that have a design flaw, so there is a tiny bit of magnification, but it is there by mistake and it makes everything worse. It is, essentially, just unintentional distortion in that case. If you want magnification, get a normal focusing optic (conventional scope, prismatic, etc).

The whole concept of magnification is really not applicable to red dot sights. A riflescope can be 1x: it sees an image, massages it, focuses it on some inner focal plane or two and then spits it out to your eye looking exactly (hopefully) the same as it came in except with the aiming point superimposed. A red dot sight, does not do any of that. It just gets an aiming point in front of your eye while trying to distort the image as little as possible.

That's why there is a perspective difference between red dot sights and riflescopes. It is only apparent at very short distances, but with a riflescope, the perspective from which you are looking at the target is located where the objective lens is. With a red dot sight, the perspective from which you are looking at the target is located where your eye is.

Vortex Defender XL Green

This is the second time Vortex' Defender XL crosses my path. I was very impressed with the original red dot version, so I was curious to see how the one with the green dot works for my eyes.
To get the details, see the attached video.
The cliff's notes version is that I am just as impressed with this one. In terms of collimation quality and parallax control, it is quite exceptional.

Primary Arms HTX-1 US Made red dot sight

I've had this RDS for a bit over two months now and I am beyond pleased with it.
Despite some spirited abuse, it keeps soldiering on.

It is a very nice RDS and being fully made in the US does not hurt either.

Delta Stryker 3.5-21x44 Wrap-up

This scope comes up a lot since I really like the configuration. It is time to do a final wrap-up of it.

It is one of my favourite scopes on the market today, especially for the money, since I naturally lean toward general purpose-ish designs. Still, while the 3.5-21x44 Stryker is relatively compact and light, it still clearly leans toward the precision side of things, which suites me very well.

Uncooled Thermal with a little bit of history

There is, as always, an entertaining discussion happening in the Hide, but I do not feel like getting into another protracted argument about comparative merits of different uncooled cores with people who do not know a whole lot about them. I mentioned that BAE is getting out of the uncooled core business. The responses were interesting.

Still, I thought some of the background on uncooled cores is worth rehashing since I was around for most of it and involved in some of it. Hopefully, you'll find it informative. If not, this post will fade like many others before it.

Here is a little history on uncooled cores from an eyewitness.

I was working at Raytheon when it was starting out and one of my first projects over there was trying to figure out how to calibrate early uncooled cores for a military project that eventually ended up going into ENVG.

The uncooled technology was first developed by Honeywell and after a while they licensed it to a bunch of people. Honeywell developed the technology, but did not ...

Something to consider

I had an interesting conversation earlier today that made me think. I was approached by a company called TourHero.

Apparently what they do is organize various tours, trips, etc in partnership with different influencers.

The influencer does the marketing, i.e. convince his/her audience to buy this customized tour, while the company does all of the logistics.

The idea is that they get several people to pay extra for a tour package which pays for the influencer in question to come along and, apparently, make some money on top of it, depending on how much the influencer is able to get out of his/her followers.

How I got on their radar is very unclear since they are very focused on the Instagram crowd and I have a very small Instagram channel. https://www.instagram.com/darklordofoptics/

My best guess is that they saw the picture of my daughter and me after her antelope hunt and made some sort of an incorrect conclusion. Frankly, the types of the things that they push require levels of narcissism that I ...

Another G&A Article

For the few of you who still pay attention to print magazines, I have an article in the latest Precision Rifle Shooter, called "Optics For NRL Hunter". For those of you who have been following my stumbling and bumbling match shooting exploits, there isn't going to be anything new there. You know what I think on the subject.
However, I still get some sort of a weird nostalgic kick out of seeing something I write printed on paper.
When I was growing up in the Soviet Union, my room doubled as a family library. I think it is some latent aftereffect of spending my childhood with books. Gen-Xers have a reputation of spending their childhood outdoors doing whatever mischief came to mind and that is true in my case, to some extent.
However, that is largely because at some point my mother got sick and tired of seeing me in the apartment with my nose stuck in the book. Every once in a while she would just search me for hidden books then kick me out of the house to go do something active. It ...

Well, that was a doozy...

My original plan was to try to set up a hunt where my daughter will have her first memorable hunting experience without working too hard.

The choice of the pronghorn hunt was largely based off of my experience in that same area last year.

The way it went last year was quite straightforward.  We drove around until we saw a large pronghorn buck.  It was a solitary animal that decided to lie down in an open area to relax.  We made a short stock, crawled the last hundred yards or so, found a good spot about 350 yards away from the pronghorn and made the shot.

https://darklordofoptics.locals.com/post/6034347/well-that-was-a-nice-morning

This year, when I decided to take my daugher on the same pronghorn hunt on the day of her 14th birthday, I figured it will be somewhere along those same lines.  It kinda was, but not quite.

Still, it worked out nicely.

In the pciture:

Q Mini-Fix with 6ARC 16" Proof Research carbon fiber barrel

Q Jumbo Shrimp supressor

Gunwerks Elevate 2.0 bipod

Telson Toxin 3-18x50 riflescope

Leica Geovid Pro AB+ LRF binoculars

Pint-sized sticky Gamechanger bag

Unnamed pronghorn buck.  It will likely get a name once it's skull is euro-ed and is hanging on the wall.

Steiner C35 Gen2 Mount
from Annex Defense

The production version of the Annex Defense's mount for the Steiner C35 Gen2 thermal Clip-on is finally here.  At $1600 (when this is published), the clip-on is an absolute steal.

I've had it for a few days, but, me being the good old paranoid me, I spent some time shooting with it before posting anything.  I had a couple of days with it prior to last weekend's match in Montana and a couple of days after.  Another to pop it on and off a few times and get a couple of hundred rounds of 6.5Grendel through the gun to see if anything shakes loose.  So far so good.

The C35 Gen2 clip-on is sitting on my 6.5Grendel AR as a part of a long running "Only One" project that I have.  It pairs perfectly with the Steiner H6Xi 2-12x42 scope.

Here is what comes in the box from Annex Defense:

The order in which the whole thing comes togethe is pretty stragihtforward:

-slide the thermal washer onto the threaded interface extending out of the back of the clip-on

-spin the mount itself onto the threaded interface (the mount is threaded on the inside) until it can go no further

-rotate the mount so that the clip-on is properly lined up to the picatinny clamp

-once you are happy with the alignment, use the three nylon tipped set screws (you'll need an allen wrench for that) to lock in the position of the clip-on in the mount.  You need very little torque on the set screws.  They are there for one reason and one reason only: to keep the mount from spinning when you tighten the timing nut in the next step

-spin the timing nut onto the threaded interface of the clip-on to lock the mount in place.  You should not need the timing nut wrench, but one is in there just in case.

Here are the pieces laid out in the order in which you will need them.

When you are done, it should look like this:

Note that the mount normaly comes with two T20 screws.  I am using two thumbscrews instead, since I am popping the mount on and off all the time.  It seems to be staying put with the thumbscrews just fine.  I am hoping Annex will offer the thumbscrews as an option.

It is not quite an equivalent of a QD mount, but we needed something with an extremely low profile clamp to fit under scopes with fairly large objectives.  As is, the mount works with most scope that have objective lens diameter of 50mm or less.

I am using with with Steiner H6Xi 2-12x42 and the two work together exceedingly well.
