The Trijicon Tenmile 3-18×44 first focal aircraft scope is a good instance of the development in merchandise that bridge the realms of precision capturing and searching. For technically inclined hunters who wish to dial their dope for longer photographs it’s an interesting choice. Over the years I’ve run three totally different samples of this scope on three totally different searching rifles, which is an effective indication of what I give it some thought.
Among its virtues are a magnification vary (3X to 18X) that’ll cowl nearly any situation encountered searching open nation, a well-designed reticle that includes helpful element with out being overwhelming, sturdy development, and a measurement and weight that isn’t burdensome for even excessive mountain searching.

Trijicon Tenmile Family
The Trijicon Tenmile 3-18×44 is one in all six fashions within the Tenmile lineup, most of that are aimed particularly at long-range shooters. The Tenmile 4-24×50 is the opposite one within the household that may do double responsibility as a searching optic, because it weighs 25.7 ounces—simply 1.3 ounces greater than the 3-18X—and shares related dimensions. I’d nonetheless favor the 3-18X as a result of I’d relatively have the decrease backside magnification setting (3X vs. 4X) and I feel the Christmas tree reticle on the 3-18X is superior to the plain MRAD crosshair on the 4-24X.
Trijicon Tenmile 4.5-30×56
The 4.5-30X56 is constructed on a 34mm tube, weighs 36 ounces, and is obtainable in two FFP ($2,810) and one SFP ($2,732) configurations. In FFP you could have the selection of both an MRAD or MOA reticle whereas the SFP is MOA solely. Its measurement, weight, and—to some extent—value relegate it to devoted long-range rifles.
Trijicon Tenmile 5-25×50
This is a SFP scope with a fundamental, virtually minimalistic, MRAD reticle. It comes on a 30mm tube, weighs 25.6 ounces, and has .1 MRAD changes on the windage and elevation. For capturing disciplines on known-range targets it’s a strong alternative, particularly for shooters that don’t take care of FFP scopes. Because SFP scopes aren’t as costly to construct it carries a $2,100 price ticket.
Trijicon Tenmile 5-50×56
This hefty scope (38.4 ounces) with its 10-times magnification vary is supposed for excessive long-range capturing. It is SFP solely and will be had in MRAD or MOA configurations. To fine-tune the elevation on lengthy photographs, the MRAD model comes with .05 MRAD click on changes, whereas the MOA mannequin makes use of 1/8 MOA clicks. Thanks to its 34mm tube it has 29.1 mils/100 MOA of elevation on faucet and 14.5 mils/50 MOA of windage. It prices $2,837.
Trjiicon Tenmile 6-24×50
This is one other SFP scope that may be had in MRAD or MOA trim. It’s constructed on a 30mm tube, weighs 24.9 ounces, and is the least pricey scope within the Tenmile lineup at $1,470. While missing the flexibility that FFP scopes convey the celebration, it’s an financial alternative for long-range shooters. The 6-24X magnification vary it isn’t very best for large recreation searching however is true at residence for ringing metal at lengthy vary and for controlling your native inhabitants of floor squirrels and prairie canine.
Trijicon Tenmile 3-18×44 Controls
The controls on the scope are all simple to control and customarily properly executed. All the weather that dial or regulate require the correct quantity of effort to show. Nothing is both too tight or too sloppy.
The format of the controls is intuitive so there’s not a lot of a studying curve to get used to the scope. The markings on the scope are cleanly executed and simple to learn. Though making the numbering a bit bolder, particularly for these of us with getting old eyes, can be a worthwhile improve.
Elevation and Windage Turrets
The elevation knob on the scope is uncovered, whereas the windage knob is secured underneath a cap. This is the best setup for many precision rifle scopes and is completely the suitable alternative for a precision searching optic.
There isn’t any profit to having the windage knob completely uncovered. Under solely probably the most peculiar circumstances would you ever wish to dial windage whereas trying a shot on recreation. Instead, it’s best to depend on the hash marks within the reticle to make windage corrections. When a windage knob is hanging on the market, unprotected, nothing however unhealthy issues can occur. Usually within the type of the knob getting knocked off its zero.
I had that occur to me a number of years in the past and it value me a pleasant bull elk. If I’m ever searching with a scope that has an uncovered windage knob I wrap it with electrical tape after establishing the zero to ensure it doesn’t budge. I recommend you do the identical.
The elevation knob is a bit of over .75 inches tall and has a raised knurled rim on the high to supply some grip. The knob turns simply and offers 8 mils of elevation per revolution. That’s sufficient for 1,000-yard photographs with most high-performance cartridges.
The scope has extra elevation than that on faucet, nevertheless. Once I set the zero on my H-S Precision 7mm PRC I had 13.5 mils of elevation left, which might get me out to 1,450 yards or so earlier than needing to carry over with the reticle. That’s a lot farther than I’d ever plan to shoot with that searching rig, aside from to fiddle on metal.
The turret is barely numbered from zero to seven mils with ticks at .1 mil intervals. So, when you dial past one revolution, you’re going to wish to do some counting and math to maintain observe of the ultimate elevation worth.
If that’s a difficulty for you, Trijicon works with Kenton Industries to create customized turrets with extra knowledge (together with a second row of numbers).
The scope offers good suggestions with every click on, although it isn’t as sharp as you’ll discover on different premium scopes. I used to be capable of dial by really feel with my eyes closed, however discovered it required further focus to maintain from inadvertently including further clicks.
Zero Stop
The Trijicon Tenmile scopes all have zero stops that perform the identical method and will be set pretty simply. The high of the elevation turret unscrews, letting you take away the turret from the scope. That exposes the zero-stop mechanism. The scope comes with a small Allen-key wrench that’s used to loosen three set screws on the mechanism. Once they’re loosened, you rotate the zero cease till the small put up on the disk contacts one other put up fastened within the base of the mechanism. You then tighten the set screws and put the turret again on.
One factor I like about this zero cease is that you may set it to offer you few clicks beneath the precise zero. When this selection is accessible, I often set it so the elevation turret can go .5 to 1 mil previous zero. This offers you some cushion to reset the elevation in case your scope will get knocked off (or if it’s important to swap to a brand new load) with out having to fiddle with the zero cease.
The one factor I don’t like concerning the zero cease is that it’s a bit mushy—at the very least on my scope. I need the cease to have a pointy, outlined wall and mine has only a contact of play in it. It’s not a serious flaw, however it’s value nothing.
Parallax
The parallax adjustment knob is on the left facet of the scope and is simply contained in the dial that controls the reticle illumination. It is about half an inch broad and has a skinny raised rim with machined knurling for higher buy. It rotates roughly three quarters of a flip (270 levels) and is numbered from 15 yards to infinity.
The parallax will be dialed barely nearer than the 15-yard mark, and I used to be capable of focus my reticle on objects 13 yards away. Being capable of deal with objects so carefully is a profit when doing dry-fire follow in a confined house (like your home).
Illumination
Illumination on the Trijicon Tenmile 3-18×44 is managed with dial that sits simply outdoors the parallax focus. It has ten settings, 5 that mild the reticule inexperienced and 5 that mild it purple. The values on the dial go from R1 to R5 a technique, and G1 to G5 the opposite. Between every depth degree is an off place, which is a helpful function.
The swap turns freely in both course, so you’ll be able to hold spinning the dial to get to the place you need with out coming in opposition to a cease. The reticle illumination is vibrant sufficient to make use of in full daylight on the fourth and fifth settings, whereas positions one by three will make the reticle seen in dimmer mild with out washing out the picture.
The scope makes use of a single CR2023 battery that gives 39 hours of energy on the very best purple setting (R5) and 94 hours on the very best inexperienced setting (G5), in keeping with Trijicon. The battery sits beneath a cap on the illumination dial that’s easy to unscrew and that’s sealed in opposition to the weather with a rubber gasket.
I didn’t take a look at the battery’s period in excessive chilly—so I don’t know if these printed figures would maintain true in excessive circumstances—however I’d all the time make certain to have a spare in my pack to vary it within the subject if want be.
Magnification Ring
The scope zooms from 3X to 18X with a half revolution of the magnification ring. The ring has a big, raised portion that’s about .67 inches broad and textured in order that it offers an excellent handhold when adjusting the scope’s energy.
The ring strikes easily by its 180 levels of journey. It is stiff sufficient in order that it’s unlikely to get knocked to a special setting inadvertently but will be turned with out undo effort.
The numbers on the ring are clearly marked and simple to learn. The scope comes with a small stud that may be screwed into the ring to behave as a throw lever. It extends .4 inches above the magnification ring and offers you further leverage to regulate the magnification degree. This is especially helpful once you’re arrange behind the rifle and wish to regulate the magnification with out breaking your place.
Ocular Focus
The eyepiece deal with the Trijicon Tenmile 3-18×44 is a European type, that means it doesn’t have a locking ring that secures it in place. Instead, it turns freely just like the diopter adjustment on a binocular.
The stress on the main target ring is pretty stiff so it isn’t prone to get knocked out of place. But the ring has a “+ / –” etched on it with a triangle between them so you’ll be able to inform the place the main target is without having to look by the scope. Once you set the main target in your eyes, I’d recommend dabbing a small dot of nail polish on the scope tube that’s in keeping with the triangle. That’ll allow you to return the main target to the proper place in a flash.
Trijicon’s MRAD Precision Tree Reticle
The major crosshairs on the Trijicon Tenmile 3-18×44’s reticle have hashmarks positioned at .5 mil intervals with a central floating dot. The hash marks are smaller on the .5 mil positions, and bigger on the entire values. In addition, the reticle is etched with even numbers, going from 2 to 12, above the corresponding hash mark on the horizontal crosshair.
It’s fairly simple to get oriented within the appropriate spot on the horizontal aircraft with out a whole lot of follow. The format is clear and uncluttered.
The “tree” beneath the horizontal crosshair has dots indicating windage in .2 mil intervals on “branches” at each full mil. Those branches are labeled 1 to 12 on the periphery that can assist you orient your self when holding over.
The width of the branches will increase the farther you drop down the tree. At 1 and a pair of mils, they prolong two mils to the left and proper of the central vertical crosshair. At 3, 4, and 5 mils, they supply 3 mils of windage dots. At 6, 7, and eight mils, the branches prolong 4 mil on both facet. And from 9 to 12 mils the branches stick out 6 mils both method.
That format is especially helpful when capturing distant prairie canine the place getting correct ranges will be practically unattainable. But it is usually good for making comply with up photographs on recreation in case you miss or have to fine-tune bullet placement.
The vertical portion of the crosshair extends 4 mils above the central aiming level and has the identical format because the horizontal crosshair—small hashes at .5 mil and bigger hashes on the complete numbers.
Optical Quality
The glass within the scope is excellent. It delivers a crisp clear picture within the heart of the view, with some distortion and lack of deal with the perimeters. Some diploma of spherical aberration is regular and exists on even the highest-price optics.
In phrases of coloration high quality, the scope was glorious. I by no means skilled significant chromatic aberration with any of the samples I’ve used and have been pleased with how they behaved underneath difficult circumstances, comparable to when your goal is sort of in keeping with the solar. All in all, the scope earns excessive marks for its glass.
Trijicon Tenmile 3-18×44 In The Field
As I stated, I’ve mounted three totally different samples of this scope on three totally different searching rifles over time and have all the time been happy with their efficiency. Most lately, I ran one on a two-week bighorn sheep hunt in Alberta that was about as bodily demanding as any hunt I’ve ever accomplished.
The scope withstood lengthy miles on horseback, banging by willow thickets alongside the river and creek bottoms, and busting by the dense, trackless pine forests we needed to traverse to get to the excessive nation.
After that, the true enjoyable started with lung-busting vertical ascents with my rifle strapped to my pack or slung over my shoulder. Much of that climbing concerned actually hanging on for pricey life, so there was no time to child my gear.
I took a reasonably critical tumble at one level, sliding 40 yards down a steep slope of jagged shale, mud and ice. I got here to a cease proper above a plunging waterfall that might have spelt critical bother had I gone into it, however because it was all the pieces on me—together with me—was fairly beat up. Other than getting scratched and smeared with mud, nevertheless, the rifle and scope held up fantastic. (I did a full overview of the rifle, an Allterra Arms Mountain Shadow Steel, that features footage of the Trijicon Tenmile.)
The scope additionally survived extra typical abuse—ice and snow, rain, mud—with none points. Trijicon has a long-standing repute for making sturdy optics—I don’t know of something extra rugged than a Trijcon ACOG—and the Tenmile scopes appear to be reduce from the identical fabric.
The latest Trijicon Tenmile 3-18×44 in my assortment is on the H-S Precision rifle pictured under. I’m nonetheless within the technique of gathering accuracy knowledge and placing the rifle by a sequence of capturing drills earlier than my overview is last, however up to now the scope has complimented the 7mm PRC properly. I’ve accomplished some capturing with it at longer ranges, as I did with the Allterra Arms rifle, and located that the scopes on each weapons tracked properly and had no points returning to zero.
What the Tenmile 3-18×44 Does Well
This scope hits a candy spot that different corporations are prone to emulate. It’s a FFP optic in a helpful magnification vary that isn’t too cumbersome and is priced pretty. I additionally like the truth that it’s MRAD primarily based. While loads of hunters and shooters will debate the deserves of MOA vs MRAD, I gravitate towards mils for sensible long-range functions. Milliradians, designed on a base-10 system, are extra intuitive and require much less math to make use of than minutes of angle.
Though when you’re a died-in-the-wool MOA shooter, however like what you’ve examine this scope right here, have a look at the Trijicon Tenmile HX 3-18×44. The Tenmile HX scopes are all MOA-only designs.
What the Scope Could Do Better
The listing of issues I’d change on the Tenmile 3-18×44 is fairly quick. I’d wish to see the numbers on the scope marked extra boldly and a second row of elevation values positioned on the turret. I additionally assume the clicks when dialing elevation could possibly be a bit sharper to offer higher tactile suggestions and management.

Final Thoughts on the Trijicon Tenmile 3-18×44
I’m an enormous fan of this scope as evidenced by the truth that I’ve mounted it on a number of of my favourite rifles and have trusted it sufficient to take it on some very massive hunts.
For a hunter trying to make the leap from a second focal aircraft scope, and who’s interested by utilizing an MRAD primarily based optic, there aren’t many scopes that measure as much as it.
