This is another subject that comes up with reasonable regularity. I did a couple of videos on focusing riflescope eyepieces a while back, but a bunch of people complained that it was too long and too technical. They were looking for something simple and to the point.
Simple and uncomplicated is not something I do well, so I figured I should try to put together a through the scope video that demonstrates the point. That turned out to be a little bit involved, but I think I've got a reasonable way of doing it. In the meantime, here are some general guidelines and the reason why this is a bit different with FFP scopes compared to SFP.
Do note that is a little different with LPVOs. Not very different, but still this applies to FFP scopes that do NOT go down to 1x. The video I am trying to put together to demonstrate this is ZCO 4-20x50.
1) Mount the scope on something steady. Do not do this handheld. If you've seen me do it handheld at SHOT or something like that, please pretend it never happened. I have adjusted hundreds, if not more, scopes over the years and developed a feel of sorts. Still, for my guns I do this on a steady platform of some sort.
2) Start out doing this with fairly bright lighting conditions.
3) Point the scope at something uniform and light colored (sky, wall, etc). The reticle should be the most prominent thing in your sight picture, so you eye focuses on it.
4) Set the magnification to something fairly high and slowly adjust the eyepiece focus to make the reticle perfectly sharp. Frequently look away from the scope at something distant. When you look through the scope the reticle should be immediately sharp without any time allowed for accommodation.
5) Once you converge on a reasonable setting, lower magnification to some setting where the reticle is clearly visible, but thin. Basically the lowest magnification where the reticle is still easily visible, but small. Repeat the adjustment process. This is finetuning, so go slow and give your eyes time to rest.
6) Repeat step 5 in somewhat lower light when your eye pupil is dilated half way or so. You will likely end up on somewhat higher magnification than step 5. This is more finetuning, so go even slower.
You should be done, but it is not a bad idea to check the setting in good light again at some future point. For most people, the eyepiece setting you converge on in step 6, should work across the board, but everyone's eye differ and sometimes you can end up with daylight setting and night time setting. I can always mark the two spots just in case if you need to switch, like you would if there were two users to the scope.
Lastly, with FFP scopes, the reticle is between the erector and the objective, so as you rack through the magnification range, with some high erector ratio designs, it is possible to have a spot where for one specific magnification, the reticle goes out of focus slightly. Make sure that in steps 5 and 6, are not sitting on one of those magnifications.
I got home yesterday and fished Steiner MPS from the mail. I am going to go live in an hour, right here, with some early impressions of it.
I originally planned to do a live show on the Rittenhouse verdict take-aways, but figured you'd want to get the scoop on the MPS first. It is an interesting new option for compact red dot sights and the last thing I needed for the red dot comparison I have been working on.
Let's talk about optics today and touch on the political stuff tomorrow.
Here is a review of the 15x56 "Big Eyes" binocular from Tract.
I ended up liking it a lot more than I expected given the price.
Here is the third installment of this series, recorded after a rather long break.
Let me know if you have any questions.

Here is how I chose to build a general purpose AR-15. That does not necessarily mean it is ideal for everyone. If you are thinking of doing such a build, this is a good starting point. Take a close look at my reasoning and see what you need to change to make it fit you.
During the last couple of livecasts, multiple people brought up a recent article in the Recoil magazine that discusses the MPVO concept. MPVO stands for Medium Power Variable optic, similarly to how LPVO stands for Low Power Variable Optic.
The article in question is this one: https://www.recoilweb.com/medium-powered-variable-optics-mpvo-the-optic-you-dont-know-you-need-170236.html
It is generally a well written piece that makes a reasonable argument. I agree with some parts of it and disagree with other parts, so there is some nuance there.
Before I get into the specifics, there are a couple of things to point out:
1) It will occasionally sound like I am attacking the author of that article. I am not. However, I also have to call a spade a spade sometimes and if I think he has no clue about something specific, I will say exactly that. I have never heard of the guy until today. I did look up a few of his other articles and he seems like a good writer and a competent gun guy. I did not, however, find anything resembling an understanding ...
There is a very fair chance that your e-mail is filled with hundreds of "once-in-a-lifetime" or "today only" deals. If you are not careful, you can end up with a once in a lifetime credit card bill next month.
I am generally not hugely pre-occupied with deals and I do not wait for a particular season to buy something. If I am looking for something specific, I usually need it and I am unlikely to spend months analyzing what deals are out there.
There are some exceptions to that, most notably with backup optics (see my earlier post on Primary Arms) and tools.
I have a good assortment of tools to use, but I have been keeping an eye out for deals on Fix-It-Stick kits since I like to have a few spread around different bags/backpacks/etc. It turns out that I am pathologically incapable of remembering to move one from bag to bag, so I ended up accumulating a few here and there I am picking another one up this time since they have a healthy Black Friday discount going on: https://bit.ly/3nTqzsL

Rather than inundate you with a long list of things we are thankful for this year, I'll just leave you with a couple of points
We should all be grateful for our families. I certainly am. I really am blessed and I wish you all to be as fortunate.
All of us who live in the US, should definitely be grateful for that. It is the greatest country in the world (I know people from other countries may disagree, but everyone has the right to be wrong) and I am truly fortunate to be here.
I made a long drive to California yesterday with my kids, so I had some time to think. As irritated as I am with Big Tech at the moment, I have to say that I truly am grateful for the modern marvels of technology. They did not give me a voice, but they sure extended its reach.
Happy tryptophan day, ya'll!
