In a world that is continuously obsessed with intermediate cartridges like 5.56 and .300 blackout, fewer people are understanding the merits of a full-size cartridge like .308 or even 6.5 creedmoore. If you are among this like few that get to shoot heavy metal cartridges and full-size bullets, consider yourself lucky.
If you can shoulder the extra weight and cost these cartridges provide, you get far better performance than any of their smaller cousins have to offer. If you’re looking for a rifle to harness the power of these rounds, for the .308 at least and m1a is a cult favorite.
The m1a, m14 or m1a1, depending on how you know it, was designed in a simpler time. Back when military doctrine stated that the Army that put the most led downrange would always win. While these rifles can be adapted for precision fire, they are often used for plinking, hunting and little more.
In a practical sense, they weigh double what an AR 15 does and lack the performance of a well-made AR 10. If you still want to shoot one of these rifles, having the best scope for your m1a can make the difference between being able to hit at 300 yards or 1300 yards.
These rifles were not designed to be used with optics, and a few idiosyncrasies will have to be addressed before you can make full use of them. Here are the best scope for M1A on the market as well as tips and tricks to make sure you don’t buy the wrong one, as well as the lessons learned from how to mount an M1A to a scope that it wasn’t designed for.

How to Choose a Rifle Scope for an M1A?
Scopes and other magnifies optics are highly technical. When you shopping make sure you’re paying attention. Small differences in technology and in measurements that you see written on the box of the scope can make huge differences in the field.
Especially for a scope that needs to perform so many things well if it’s going to be mounted on an m1a, you need to get the technical aspects of the scope correct. Broadly speaking here are the main categories what to look for in a few details that you might want to consider before you go shopping:
Size & Weight
When it comes a size of the optic that you select, is going to depend more what you are doing with your rifle to the type of rifle you have. With this means that you are plinking, and not likely to take shots past 100 yards, you do not a very large objective bell. However, if you are a long-range hunting at the edges shooting light, you will need every millimeter you can get. Be sensible, and by the smallest scope that you can get away with.
The m1a is a heavy rifle. There’s no getting around the 9+ pound weight that you are going to be carrying if you decide to go with this full-size rifle. Adding a scope is only going to make it heavier. However, adding which this rifle is not always a bad thing.
When you use a rifle that is going to be shot more than it gets carried, recoil can become a substantial problem early on. Adding 2 pounds of scope to this rifle is going to help smooth out the recoil considerably and make it easier on your shoulder and head to shoot for long periods of time.
If you are buying a scope that you can use to compete in the national match or surplus competition, consider getting a heavy scope and steel base. This will help dampen the recoil by adding weight. However, if you are using your M1A to control hog population on a farm or as a general use firearm in case of emergencies, try to keep weight to a minimum.
In these circumstances, you are much more likely to carry rifle you are to be shooting it and that extra weight is going to make it much more difficult carry in the field.
Budget is a dirty word no one wants to talk about. Optics are expensive. Good glass on a rifle can double or triple the cost that you paid for the rifle itself. There’s no getting around that equipment costs money, but carefully deciding on which features are essential and which ones can be eliminated is the best way to save money.
When it comes to optics, proprietary features and brand names are the most expensive options you can get. Proprietary features are great, sometimes. Truly innovative companies like Leupold and vortex put out reasonably priced scopes that combined proprietary features and prices that are available. Companies like US Palm and NightForce take advantage of charging money for their brand name and providing very niche capabilities.
Try to stick to companies that provide customer support and warranties, but don’t buy from a company simply because it’s a boutique brand. There are companies that make their entire business model off of simply reselling the same features and level performance of their competitors, but it three times the price. Everyone would love the tricked-out night vision, ebr stock, and custom Zeiss scope equipped rifle, but at what cost?
Depending on the type of shooting you’re going to be doing, you’re going to need a different scope that someone with the same m1a. Scopes are a lot like vehicles. You don’t the same thing with a minivan that you do with a pickup truck.
Much the same way you don’t plink with the same scope that you are going to be hunting with. However, a few features that you are going to want regardless of which will be doing are the following: waterproof, fog proof, O-ring sealing, dry nitrogen purging, fully multicoated lenses, and single piece construction.
Even the cheapest imported scopes on the market have those features. At a minimum, this will allow you to comfortably carry your rifle from your truck to a deer stand or into a range and shoot with it. Whether or not your scope lasts a last a long time, has glass clear enough to shoot at 1000 yards, or will allow you to easily make adjustments with target turrets, is completely up to the manufacturer’s level of quality.
Like everything else in life, there’s a difference in what you pay for and there’s a difference between an affordable “Walmart Special” and an expensive Trijicon ACOG.

Eye relief is defined as the distance from your pupil to the eyepiece of your rifle scope. This is important for a number of reasons, most notably on M1A because you have to be within the eye relief that your scope is designed for in order to see through the scope without errors.
Eye relief is extremely important for M1A because if you plan on using a scout scope or want extra eye relief for faster shooting, you need to make sure that the scope you buy will facilitate this. Most long-range and precision rifle scopes have what is called critical eye relief. This is where there is a very specific distance your pupil must be at from the eyepiece of the scope.
This is a problem for fast shooting, and for hard recoiling rifles. Typically, long range rifle scopes have very short eye reliefs, which can cause scope bite and take longer to shoot through. Look for scopes that use noncritical eye relief, or scout scopes that have extended eye relief of several inches so that you can set the scope up the way you want and keep your eyebrow safe.
Eye Box & Fast Focus Eyepieces
If you’ve looked your scope and seen a thick black ring around the edges of the sight picture, you know exactly what it means to have a tight eye box. An eye box refers to the amount of lateral movement the scope will allow your pupil to have when viewing through the scope before you start to experience parallax errors and losing focus through the prism.
This is a very technical setting on a scope. Essentially speaking, you want to have a generous eye box and a fast focus eyepiece. This will not only allow you more flexibility in the shooting angles that you are able to utilize your scope, it will make sure that when you shoot your m1a, having an extremely sturdy cheek weld is not your top priority.
Because m1a’s are notorious for having bad cheek welds while shooting, and with tall scope set up it’s very easy to cant the rifle, having a fast focus eyepiece in generous eye box means you don’t have to worry constantly about holding the rifle perfectly still and straight. You just want to be able to hold the rifle straight enough to reliably use the scope, and no more.
Getting a Good Mount
Mounting an optic on m1a is tricky. Mainly because they were designed before optics were a mainstay of the individual soldier and commanders didn’t think that an optic would be feasible for everyone. Nowadays, especially in the civilian world, optics are the norm and not the exception to the rule.
While there are a ton of different mounts available for every varying of the m1a, you’ll typically see one of two options. People are using the factory installed scope mounting base along with user supplied rings for a scope set up, or they are buying an aftermarket mount to put an optic over the bridge of the rifle.
Putting an optic over the action of the rifle is a balancing act. If you mount the optic too low you’ll be the ejection of brass and keep the gun from operating. If you mounted too high, you won’t be able to get a cheek weld to shoot accurately.
Several companies a step up to the plate and are producing excellent aftermarket mounting options that supply a picatinny rail for use with virtually all rings and mounts available for optics these days. These range in price from just a few dollars for steel versions made for Springfield Armory, all the way out to several hundred dollar titanium models made for enthusiasts who are competing.
The difference in performance between these different mounts is suspect, just make sure you get a decent mount that is made to specifications and is durable enough to last. Typically, manufacturers make mounts available for the rifles including all the current manufacturers of m1a’s.
Features You’ll Want for Your M1A
Other than general quality and workmanship, there are a few things you to keep in mind when shopping for a scope and getting it mounted on your m1a. These are specific to this rifle because it was designed during a time when magnified optics were not common place for the everyday soldier and the rifle is not as easily adapted to using a scope as others.
Get It Professionally Mounted
Mounting a scope on an m1a is tricky. You either have to use a factory supplied scope mount, if you have a Springfield Armory model, or you have to have an aftermarket scope base or rail installed over the bridge of your rifle.
Trying to install a scope mounts of questionable quality, when you don’t know what you’re doing is a wonderful way to damage a rifle. If you want to spend several hundred dollars in scope and mount combination, make sure you leave some money in the budget to get it professionally mounted and bore bore-sighted.
The worst thing you want to happen is to strip out the mounting screws on your rifle or break the mount your scope you just bought trying to improperly shoehorn it together. This is especially true of loaded and super match versions of these rifles that are made for maximum accuracy.
As Low A Mount As Possible
Mounting a scope on the m1a means that you will most likely be sacrificing a secure cheek weld to the rifle when you shoot. This is just the nature of having the ejecting brass fly out of the top of the receiver, rather than the side like modern rifles.
Once you add in the height of an objective bell, the thickness of a mount, and the height of your rings you could be looking at over 2 inches of elevation above the bore axis and comb of your stock. This is a recipe for canting while you are shooting. Not to mention, most people are not used to shooting full-sized cartridges and repeatedly shooting a .308 without a cheek weld is going to leave you bruised and battered.
To avoid that headache, take your rifle to a gunsmith and have a mount your scope as low to the bore axis as possible. Just make sure that it doesn’t impede the function of a rifle.
A Great Warranty
M1a’s typically see harder shooting and more abuse than bolt action or other hunting rifles. This is most likely because they are seen as war rifles and workhorses rather than heirlooms. Any scope that you put on a rifle that you plan to thrash on needs to have a great warranty.
Especially considering that m1a’s experience for more recoil than most other guns and are shot and semi auto, often quickly, you can imagine the abuse the scope is going to see in its lifetime mounted to one. You don’t want to buy a scope from a fly-by-night import company that won’t have your back if you invest several hundred dollars and the product, only to leave you hanging when their scope breaks during normal use.
Make sure you buy from a reputable manufacturer that is going to be around long enough to actually honor the lifetime warranty they offered you.
Generally speaking, most people don’t need target herds. Target allows you to make it on the spot adjustments to your rifle scopes zero and quickly return it back to the way it was.
Target turrets are best use was shooters who can reliably call when and make adjustments on the fly. Typically speaking, the people shooting m1a’s are rarely looking to take advantage of extremely long-range marksmanship fundamentals that can be applied through target turrets.
However, if you like to use highly technical equipment, stick with it. Target turrets require a learning curve that you have to sit through, and that includes putting up with them snagging on every strap, vine, and obstacle that comes remotely near your rifle.
With the multitude of options on the market today, there’s never been a better time to buy a scope for your M1A. However, be very difficult to sort through the seemingly endless options available online. The best thing you can do for choosing the best scope for M1A is a decide how you will be using your rifle, sort through the brands and styles a scope that you like and determine how much you’re willing to spend on a scope.
If you do these things before you go shopping, you’re more likely to end up with a product that you will enjoy shooting with. Make sure the scope that you actually enjoy, not one that you feel like you have to compromise with. For the first time ever, we can truly have magnified optics that do just about everything. Compromise is a necessity with scopes anymore.
Just make sure that once you settled scope and purchased it, you get it mounted up to your rifle and cited in. Take it to the range as often as you can because the best scope in the world doesn’t do you any good if it’s in your gun safe.
