Perfect Example of Why Numbers Matter
And that you can be a perfectly competent shot with zero understanding of what's happening
November 06, 2023

There is a thread on the Hide that brings back the topic of drop tests, but in an even sillier way than is typical.  Someone over there has already tried to get me to chime in, but I think I will skip that thread.  I have tried to explain why this is stupid on the Hide before, but was mostly met with an online equivalent of a blank incomprehending stare.

I will give it a shot here for albeit briefly, since it is a good follow-up to discussion I had with SlavGuns on Arken optics: https://darklordofoptics.locals.com/post/4779477/starter-precision and starter precision scopes.

This most recent Hide has a link from a gentleman who has an Arken EP5.  He shoots a plate at 1000 yards, then takes the scope off the rifle (it is in a QD LaRue mount, which is already not a great idea), chucks it 25 feet onto soft dirt, walks over to pick it up, mounts it back on a rifle and hits the plate again.  Then, he proudly announces that the Arken EP5 is good to go.

I have no idea who the gentleman is, so none of this should be viewed as an attack on his intelligence or integrity.  Smart people say and do stupid things all the time.  This is CLEARLY not something he has ever bothered to think about.  He likely saw some knuckle dragging lunatic on Youtube do this.  It probably looked cool.  A lot of this stuff makes sense if you do not bother to think about it.

There are several problems here.  The most obvious, aside from the fact that his "test" is just stupid, is that he looked at one scope and pronounced EP5 as "good-to-go". 

I just had a livestream with SlavGuns and out of six Arkens he had, three had problems, including some Arkens.

All of this is anecdotal data, but six data points are a lot better than one (deeply flawed) data point.

I have an Arken scope here.  It works great.  However, having talked to many people with Arken scopes, I think my experience with it is not representative.  When I talk to people who buy Arken scopes and who actually shoot, they tell me they see these go down in every competition they have been to.  Arken did a great job getting many scopes out there.  Now, they need QC and engineering to catch up with their sales and marketing.   

As far as the test itself goes, aside from the fact it is meaningless on a sample of one, it really does nto tell us anything. If you drop your rifle in the field, you should check zero.  If you have a decent quality scope and something shifted, seven times out of ten, it is the mount.  If you have a QD mount, it is probably nine out of ten or higher. 

As far as the impact itself goes, what people at rifle scope QC departments do to their products to check for zero shift is orders of magnitude more severe than chucking it onto the ground. 

Now, intentionally dropping the whole rifle with the scope is equally stupid since depending on the exact angle, what it hits, the exact type of mount, how well the whole thing is bedded, the types of turrets the scope has, where the rings happen to be, whether it is fast focus or traditional eyepiece, and a myriad other factors, you can get very different results.  With this attempt of a test, it is impossible to correct for all the variables, so when something goes wrong you have no idea what the root cause is. If nothing goes wrong, you have no idea if that is repeatable.

It does provide ample opportunity to rig the results to get what you want.  I once saw this test set up so that the product of a company the reviewer hated was in a QD mount, while the other product was in a fixed and properly torqued mount.  Naturally, the QD mount shifted and it was blamed on the scope.

All influencers claim impartiality and all that.  However, most of them live off of affiliate links and it is very hard to not bias toward what pays you more.  That is one of the reasons I was so happy to see SlavGuns raise the issue of 50% failure rate on his Arkens.  A little intellectual honesty goes a long way.

That is also why when posting affiliate links, I tend to prefer to deal with large companies that carry many brands, like Brownells or Eurooptic, for example.  It makes no financial difference to me which product I recommend, and as the memebrship here grows, I hope to phase out the whole affiliate business completely.

I do not think most reviewers/influencers rig the results (although some clearly do, just based on how they position the cameras and do the tests).  

As the (slightly modified) saying goes, "never ascribe to malice what can be adequately explained by incompetence".

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.

Weekend Roundup, of sorts

Weekends is when I catch up on the political stuff and I am not convinced that brings out the best in me.
https://open.substack.com/pub/darklordofoptics/p/weekend-roundup?r=y4q3j&utm_campaign=post&utm_medium=web&showWelcomeOnShare=true

Still, there is a lot happening and I do not like most of it.

Question:

I am looking for a pair of Binoculars for Total Archery Challenge.
So spotting targets from 16yd to 130yd.
I don't need range finding, I don't need imagine stabilizing.

What are good options to look at under 1k?

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 ...

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.
