In Part 2, we learned that the peep sight has been around for a very long time. But following the American Civil War, the entire world became intensely interested in shooting for about 60 years, and target shooting was at the top of the list. World-champion target shooters were regarded like NASCAR drivers are today.
Because of all this interest, the common peep sights that were already at least 50 years old, and perhaps as old as a full century, started to change. By 1870, designers were innovating again. One of the most famous innovators, and the man whose designs are still impacting battle rifles 125 years later, was Col. Buffington of the Springfield Armory. In 1884, Springfield selected his sight for the U.S. .45-caliber, single-shot military rifle — the gun we call the Trapdoor.
The Buffington rear sight is both a peep and several different open notches. It sits 10-12 inches from the eye, yet is easily used with practice. Adjustable for both windage and elevation, it increases the accuracy potential by sharpening the sight picture.
As far as I know, the Buffington sight is the first use of a peep sight on a rifle that was intended for all combat troops. It worked so well at ranges of 500 yards and beyond that the American Army used it on all versions of the Krag and the M1903 Springfield, as well. Even though the peephole is located 10-12 inches away from your eye, it still works with precision.
The U.S. Army was so satisfied with the peep sight that they put it on the O3A3 Springfield of WWII, the M1 Carbine, the Garand, the M14 and all models of the M16/M4. It’s an easier sight to learn and far more precise than an open notch. Only in recent years have our Army and Marine Corps begun to experiment with optical sights, with the declination of the peep sight.
The refinement of the peep sight
But it wasn’t the Buffington sight that brought peep sights to their highest level. It was a challenge in 1873 that came from the champion Irish rifle team to any team of riflemen the Americans could put together for the championship of the world. No one, including the Americans, thought the Irish would lose the match; but just shooting against them was such an honor that we put a team together, built a thousand-yard rifle range and two firearms companies — Sharps and Remington — each built long-range target rifles for the team members to shoot.
The Irish shot Rigby muzzleloaders that were considered the most accurate in the world. No one thought a breechloader had a chance against them. And Rigby, himself, was part of the Irish team!
Until the year of the match (1874), there were no peep sights with vernier scales in the U.S. The best anyone could do was adjust their sights by 1/200 of an inch. At close ranges out to a maximum of 300 yards, that’s good enough; but when the distance is 800, 900 and 1,000 yards, the sight has to adjust in the thousandths of an inch. The way to do that was to add a vernier scale to the sight. So, both Sharps and Remington did exactly that.
A vernier scale is a scale of numbers that aligns with an index, making it possible for the naked eye to see measurements as small as one ten-thousandth of an inch, even though our eyes cannot actually see things that small. The vernier scale magnifies the final measurement for us through an ingenious scale of lines that are 10 times or 100 times larger than the measurement it’s measuring.
This closeup shows the Ballard rear peep sight from 1876. This is a common short-range (up to 300 yards) rear sight that’s adjustable to 1/100 of an inch, with care. There’s no vernier scale on this sight, so it has to be read directly. There’s a lot of interpolation required, and I have to use a jeweler’s loupe to read it that close.
This is a vernier scale on a peep sight. The offset index marks on the small scale align with the sight index marks, but only one of them is aligned perfectly. This allows you to “see” measurements as small as 1/1000 of an inch.
This Ballard front sight from 1876 uses an aperture! It was hand-filed to the correct size for the 20-rod (220 yard) bullseye target. It also works perfectly for a smaller 100-yard bull.
The results of the first international match at Creedmoor was a win for the U.S. team; but the score was extremely close, and the Irish team had fired one shot at the wrong target — losing the score. As far as the world was concerned, the match proved nothing about the superiority of muzzleloaders or breechloaders. However, the next year the U.S. won again in England, and this time the score was more conclusive. The breechloader had finally arrived on the target scene, and peep sights were accepted, though most shooters were using scopes if the rules allowed it. And the day of the precision peep sight with a vernier scale had finally arrived.
The American shooters positioned their rear sights on the heel of the butt, giving them the maximum separation of the front and rear sight, but requiring the shooter to lay down with his feet toward the target and balance the muzzle on his shoes. This odd position was given the name Creedmoor — after the range — and has every since defined that style of prone shooting.
Not every nation adopted the peep sight, and some who were as well-regarded as the Americans (namely the Swiss), shot very well with the older post and notch. They used it right on up through the 1960s. The US, Canada and the UK stayed with the peep sight on their battle rifles because it was quicker to learn, faster to use in battle and more precise.
Notice, also, that target shooters were using front aperture sight elements in the 1870s! Until a few years ago, I thought front apertures were an invention of the 1970s, but they’re at least a full century older. They came about because of changes from square targets to round targets around the mid-1870s.

Today, we’ll look at peep sights. Do you think a peep sight is a modern invention? Wrong! Despite what Wikipedia says, peep sights date from at least as far back as the 1840s and perhaps even a half-century earlier. There were sights enclosed in tubes during the American Revolution (1775-1783), but those had not yet reached the full development of the sights I will discuss today. By 1840, peep sights were being offered by a great many rifle makers.
The first peep sight consisted of a round, flat plate with a hole drilled through its center. It was mounted on a threaded stalk; and when turned, it could be screwed up and down for vertical adjustment. One-half turn was all that was required, because the plate was the same on both sides. It was located on the tang of a rifle and was used in conjunction with a very fine front bead sight that was mounted atop a tall thin post. This early peep sight has been called a lollipop sight for more than a century because of the resemblance to that candy.
This lollipop sight is from a later schuetzen rifle, but it’s very similar to ones made before the American Civil War.
The front sight was so thin as to be fragile, and so was enclosed in a steel tube — or what we now call a globe. The earliest type of front bead was made from pig bristles that were touched on their tips by a red-hot iron. The heat caused the bristle to melt into a tiny ball that became the bead. The other end of the bristle was stuck in a small piece of soft pine and covered with shellac to hold it in place. The piece of wood was then attached inside the front tube, completing the sight. Later front posts were filed from steel, but they could never be as thin as the ones made from pig’s bristle.
This steel front post and bead is many times thicker than the pig’s bristle front sight mentioned in this report.
Using the peep sight
To use the peep sight, the shooter looked through the hole in the plate (the peephole) and focused on the front bead. The bead was then held either in the center of the target or just under the center, depending on the type of targets being used. An early target was a wooden shingle blackened by fire and scraped white in the center. This white spot was called the mark, and early target shooting was called “Shooting at a mark.”
You’ll notice that I didn’t discuss where the front bead is supposed to be positioned relative to the peephole. That’s because it doesn’t work that way! If you look through a peephole and keep both eyes open, your brain will automatically center the bead in the center of the peephole, because that’s the source of the brightest light.
From the shooter’s perspective, all he does is look through the peephole and put the front bead on the target. His eyes do the rest. That’s why the peep sight is so much more precise than sporting types of open sights.
When the front sight is a square post, it works the same; but you have to estimate the location of the middle of the peephole. On some sights with large peepholes, that can be difficult. It’s still many times faster than a post-and-notch sight set and at least as prercise.
This is what a square-post front sight looks like through a peep. The aim point is 6 o’clock on the bull.
The front aperture
Around 1874, a new type of front sight came into widespread use. It was an aperture atop a post, and the reason it took until 1874 to come into use was because most targets weren’t round until then. Most shooters shot at targets that were squares, so a round aperture wasn’t of much use. But when the American Standard target came into accepted use (the National Rifle Association lobbied for it), it brought the front aperture with it.
To use this type of front sight with the rear peep sight, you look through the peep and focus on the front aperture. Center the black bull in the aperture, and you’re done. As long as your front aperture is very close to the same size as the black bull downrange, all you have to do is align a series of concentric circles.
This is what you see through the peep sight when the front sight is an aperture and the bull is round.
Keep both eyes open!
It isn’t just a good idea to keep both eyes open when using a peep sight — it’s absolutely essential to their proper operation. I did a blog on this back in 2009 that gave you a quick experiment to conduct. If you do so, you will discover why you must keep both eyes open to use peep sights!
In what era do you place the movie Quigley Down Under? Be careful, because the rear sight on his rifle had not been used on an American rifle before 1874. That was the year the UK champion Irish Rifle Team challenged the US team to a match to decide the world championship. The US had no team at the time of the challenge, nor did we have any standard rifles that were up to shooting the 800-, 900- and 1000-yard distances involved. Even the rifle range known as Creedmoor was specially built for this challenge match.
To help the American team, both Sharps and Remington made special Creedmoor match rifles fitted with the very first vernier rear peep sights ever used in this country. They also had wind-gauge front sights to adjust for the drift and winds on the range.
When I return with the next section of this report, I’ll show you what an advancement this really was.

Edith has been after me to write this report for over a year. I’ve been researching it and believe I can do it some justice, but this is a large topic. And it’s a fundamental one — like learning to shoot a handgun one-handed.
I’m going to make the case that the scope sight has destroyed the potential of more shooters than anything else. Not that scopes don’t work, but that they work too well. It’s my opinion that every shooter who is able (and that’s a lot more people than are willing to admit it) should first learn to shoot with open sights; because in doing so, they learn the fundamentals of breathing, trigger control, follow-through and perhaps many other basic components of accuracy as well.
There are several ways to go about this, and I’m going to present it in sort of a chronological sequence. The first guns had no sights at all, but that was okay, because they also were not at all accurate. Trying to aim one of them was almost a lost cause. I’m referring to the early hand cannons.
I see these guns coming to auction on Gun Broker from time to time, and the dealers sometimes list them as “target guns.” What a joke! These guns have wide, flared cannon-type muzzles, no sights and are the antithesis of a target gun. I think people list them that way because they have no notion of how a gun works, and the words they choose are for effect, only.
The first sights were nothing but reference points on the muzzles of guns. Sometimes, it was a raised bump at the top of the muzzle, and other times it was a groove or notch — just something the shooter could refer to when aiming the piece. The bead on a shotgun barrel is very similar to this kind of sight; and for the accuracy potential of the guns that had them, they were sufficient.
The simple bead is all the sight a modern shotgun gets. In essence, a shotgun is much like a musket of old.
The Kentucky rifle ushered in a new type of sight that, while not exactly new on the Kentucky, was certainly made famous by association with it. I’m referring to the low front blade that stood one-eighth inch tall or less and the wide rear vee that was equally low. These sights are so vestigial that they always look worn out to me, yet they’re capable of remarkable accuracy.
By the way, the term “Kentucky” is back in vogue for the types of American long rifles made from 1730 and afterwards — they have long barrels of relatively small caliber. Revisionist historians have tried to shove the title “Pennsylvania” down the throats of shooters and collectors for the past 60 years because most famous of these rifles were made in that region and not in Kentucky, which is just where they were carried and used. The term Kentucky rifle was originally used in Daniel Boone’s time because he explored the Kentucky region and both he and those who went with him carried this style of rifle. It was further popularized in a song during the War of 1812; and although it referred to a group of men in that song, rather than to their firearms, the name stuck.
The fine front sight blade on an early Kentucky rifle is so low that it appears to be worn out. It gave a fine aiming reference to good eyes.
An early Kentucky rear sight is a wide and shallow vee.
The early sights on a Kentucky rifle were low and fine. They gave a very small, sharp sight picture that resulted in extreme precision when good eyes were used.
Most shooters who see these primitive sights today think they’re not capable of accuracy, but history is full of anecdotes that prove otherwise. One of the more famous stories is the shot made by Daniel Boone during an Indian attack, when Boone shot a sniper in the forehead at a measured distance of more than 200 yards. It was a first-shot kill, and was apparently not considered to be that special, given the remarks that were made at the time.
A shooter with good eyes could “draw a bead” using as much or little of the front sight as he chose. Once a person became familiar with his rifle, sighting this way became second nature.
Paper targets found in the possibles bags of shooters prove these old rifles with their simple sights could often group their shots in one inch and less at 100 yards, though 60 yards was far more often the distance for a marksmanship contest. Because wood planks were the preferred targets of the 1700s through the 1860s, not too many original paper targets survive, though the older guns were often still being shot when paper targets came into widespread use after the American Civil War.
The term Kentucky windage stems from another special way the earliest type of sight was used. While the sights were often mounted on dovetails that could be moved left and right, it was much easier for the shooter to simply use a sight picture that compensated for the necessary windage. In other words, hold the rifle so the front sight appeared at different places on the rear vee. Since the need for windage changes with both the distance to the target and the wind, this is a very flexible way of doing it. The very fact that the term is “Kentucky” windage proves, yet again, that the popular name for the rifle was Kentucky and not Pennsylvania.
By holding the front sight to one side of the vee in the rear, the shooter controlled how far to one side the bullet went. This is called Kentucky windage.
Not made today
You’re not likely to see this early style of rifle sight today. The problem is that when Kentucky rifles are made new today, the makers almost never select the early primitive sights described here. Instead, they either use sights that are appropriate to rifles made at the end of the black powder era or they use sights that are even more modern, in the belief that they’re better and more appreciated by the customer. Perhaps they are, but only because the customer has little or no experience with the early, very primitive Kentucky sights.
The sights most often seen on guns we call Kentucky rifles are not the early Kentucky style, but the later plains rifle sights that most muzzleloading rifles had from about 1820 onward. The front blade is taller than the traditional Kentucky blade described above, and the rear sight is taller with a more of a buckhorn design. Many of these later sights are adjustable, or they have features like folding express leaves of different heights.
The American Civil War did much to mature open sights, but not the sights on the military guns. However, the civilian models evolved quite a lot — starting around this time; by 1875, they were as advanced as they would get for another 75 years.
After the American Civil War, front sights grew in height and gained some form like this one from 1867.
This post-1860 rear sight has two leaves for two different distances. Notice that the shallow vee has become a notch.
They also started to branch off into sporting sights and target sights. The sporting sights became more like the style that had been called target sights before 1860, while the target sights evolved into units capable of the greatest precision.
The driving force for this rapid advancement was a worldwide interest in target shooting. It exploded onto the American scene when, in 1874, the U.S. decided to accept the challenge of the Irish National team for the championship of the world. No one expected the Americans to make more than an honorable showing; but when the smoke cleared on the Creedmore rifle range, they were the new world champions!
The target sights they used were one of the special advantages they brought to the field, having increased in precision half an order of magnitude just for this match.
In the next report, I’ll show you how the sporting open sights continued to evolve plus what happened to the target sights.
