Well, a few months ago when I wrote the last article, I had a few tests I decided to run at our spring Precision Optics Workshop and the great folks who attended were all willing guinea pigs.
In the previous article, I postulated that the ability to accurately estimate the range to a target using a graduated scope reticle would be limited by the capabilities of the human eye, and that capability would be somewhere between 1 and 5 arc-minutes, but I didn’t exactly know where to set the bar. My best guess, given glass quality and atmospheric effects was about 2 arc minutes.
To test this, we played a little game with 10 participants. 5 “shooters” with optics greater than 20X and 5 “shooters” using optics less than 20X. The scopes used were a fairly representative sample of the common glass out … Read More »
Some of mankind’s first applications of the principles of ergonomics were with weapons. It probably started with the smoother rock,and evolved into the club or spear that was easier to grip, to the more balanced sword, down through the ages until eventually we arrived at the blocky polymer grips of today’s popular autopistols. Rifle stocks also, through this process of evolution and engineering continuous improvements, have come to be a good general fit for the average shooter. “Good general fit,” however, has never appealed to the “precision” rifleman. Now, this peculiarity isn’t just about looking cool and basic comfort. The shooter’s physical control over the rifle is dependent on their interface with the action, barrel, optics, and stock or chassis.
When everyone was still having gunsmiths carve wooden stocks, the answer to optics was the Monte Carlo style raised comb, which … Read More »
One day in the late 90’s I went shooting with some friends from work out on a piece of rural property one of them owned a little east of Cincinnati, Ohio. I remember my hearing and eye protection drew a guffaw from one old timer who made some remark to me about just having to “toughen up my ears,” to which I responded “isn’t that called hearing loss?”
I have almost 20 years of professional experience protecting people’s hearing in the workplace. I could go into all kinds of scientific details about the effects of impulse noise on hearing, but that wouldn’t be helping the “too long, didn’t read” crowd – you know who you are. So here’s the quick and dirty version:
There are 2 ways to prevent sound from entering the ear … Read More »
So I’m going to try really hard to stay in my lane in this article, as the saying goes. The question at hand: to chest rig or not as a “citizen carbine operator. “ Before anyone freaks out too badly, because I can already sense blood pressures rising from an army of keyboard commandos ready to deal out a tirade of punishing remarks, let me advise you to just chill for a second. Let’s apply some logic and work our way through this, mmmk?
Let’s talk nomenclature first, from back to front: when I say “operator” I realize that in military circles this refers specifically to members of SEAL Team 6 and 1SFOD-Delta. In this article, we’re not talking about them. We’re talking about John Q. Public who owns, and may find occasion to use or “operate” a carbine for defensive … Read More »
Prioritizing Your Defensive Dollar – By ADC Instructor Michael Lake
We all know that time and money are finite resources and most of us normal folks have to make careful decisions about how to spend them, after all, most of us hand more than 1/3 of it to Uncle Sam so he can piss it away. That doesn’t always leave much for keeping a roof over our heads, meat on the table and the wolf from the door. Most of us know what our rent or mortgage payment is, and we budget for that. Most of us have some idea how much money we spend to feed ourselves and families, and we budget for that. We keep track of our time and plan for our day jobs, domestic chores, and recreation time. When it comes to keeping the wolf from the … Read More »

Precision rifle shots can be taken from a variety of field positions, however, it is widely accepted that shooting from prone offers the most stability, it’s also typically the first position used while learning scoped rifle-craft. What makes the prone position most stable is its low center of gravity and maximum contact with the ground for both the rifle, and the shooter. The most stable geometric shape is the triangle; therefore, the rifle is most stable when it has 3 solid points of contact with the ground. The front of a rifle supported by a bipod creates 2 of these points of contact. Stabilizing the rear of the rifle when shooting from the prone position can be accomplished in a number of ways; but is made much easier with a physical support of some kind, such as … Read More »

There are a number of different names for them: “bug out” bags, “72-hour” bags, “get home” bags, etc… They all refer to a duffle-bag full of stuff that may mean the difference between life and death, or at least between marginal comfort and severe discomfort during an emergency situation.
There is also no shortage of opinionated articles written about what these kits should contain, and for the most part, the advice out there is OK. Face it, survival is what we do, it doesn’t take a PhD to figure out what things might provide a survival advantage during a societal breakdown.
Fortunately for us, total societal collapse is probably the least likely scenario we need to prepare for. Oh, I’m not saying that it can’t happen or that it eventually won’t happen, but my bet is that it won’t happen the way most people … Read More »

So you need a scope for your precision rifle and there are just too many confusing options… let me take a few minutes to help you sort some of this out. There are a lot of other articles written by a lot of other people covering some of this stuff, albeit partially, so here’s my effort to put some of the information in one place:
Question 1: What do all the numbers mean?
Answer: The first number or set of numbers refers to optical power, which is measured in units of magnification that, in industry jargon, are referred to as “X.” A 4X scope magnifies the image 4 times. In other words, a 10 inch target viewed through a 4X optic would appear the same size as a 40 inch target at the same distance viewed with the naked eye. Fixed power scopes … Read More »
Hey boys and girls, you’ve had a few months to practice all of those techniques we talked about in Sinister Studies 1 through 6, and hopefully you’ve squared away your eye dominance as well like we discussed in Sinister Studies 7. This next installment isn’t going to address technique as much as it will be an equipment review.
My introduction to shooting was competitive riflery and despite my interest in other shooting disciplines, throughout the years I have always had a special connection with shooting at distance. Most of my competitive shooting was done with match-tuned M14’s and M1A’s, which can be excellent performers. When it comes to precision shooting however, there’s just no substitute for a scoped bolt gun. So in this installment, I would like to explore some options available for the left-handed rifle marksman.
A few years ago I signed up for some precision … Read More »
There are plenty of holster options out there, unfortunately, most of the good ones aren’t typically what you find at the local gun and sporting goods stores. They certainly carry a variety of holsters, but for critical uses like concealed carry, the holster is an integral part of your overall weapons system.
Here is my criteria for a suitable concealed carry holster:
1. The holster must STAY OPEN when the firearm is drawn, this implies the material must be something durable like rigid leather or Kydex.
2. The MUZZLE must be protected or covered. Holsters that allow the muzzle to completely protrude, such as competition-style holsters, are not desirable for defensive use for a number of reasons.
3. It should ATTACH firmly to the belt. There are some minor exceptions that are very specific in nature but IN GENERAL, for a defensive carry holster, it should … Read More »
