Range: How Far Away is Your Target?

This civilian semi-automatic M1A with a .308 caliber is an advanced upgrade from its predecessors and is very popular among all types of shooters because of its versatility and usefulness of the entirety of its features.

A standard M1A has a barrel of 16 to 22 inches. For an aspiring shooter, the longer the barrel and the more he/she can magnify, the further a user can aim with this rifle. So, we could say that the M1A shoots with admirable accuracy and ease at 200 yards, with a less than 1 MOA (Minute of Angle). (1 MOA spreads about 1″ per 100 yards)

However, with enough practice and the right scope on this rifle, you can have a clean kill or a dead-on-target shot at 500 yards and more. What you need to know is that at a long range (>350 yards), you need a magnification of 10x and higher on your scope to achieve ideal accuracy.

For the most appealing mid-range distances (150 - 350 yds), you need a 6-9x magnification and for a small range of up to 150 yards, you need a rather insignificant power magnification of 1-5x on your scope. You can aspire for longer distances and success with this gun, all depending on the speed of the wind, individual skills, quality of the scope, ammunition, angle, etc.

With persistence and regular practice, you can achieve accurate shooting at even 1500 yards! So, don’t be afraid to reach for the farthest of aims with any of the scopes that we present here and be inspired to shoot for better and more accurate activities with your M1A.

How to Choose a Rifle Scope for the M1A

Prior to purchasing a scope, you need to define your purpose. Whether you are preparing yourself for an in intense close-up "ambush", or a challenging long range set-up, you need to feel comfortable and excited to adjust and work with, your new scope.

There are several factors that contribute to this mindset and one of them is becoming familiar with the most significant aspects and attributes of a scope, such as:

Magnification 

Magnification is the power of the scope that grants you a more precise aiming by enlarging the size of the target through the scope. Commonly, a riflescope's specifications will be indicated in numbers such as  3.5-10x50 or 4x32 (power-power x objective lens diameter).

The first number (3.5-10) indicates the range of possible multiplication of the scope and how your target's size and distance modify in the reticle. The higher the magnification properties of a scope, the larger the objective lens will be, and the more useful it will be in diverse light conditions. It is also preferable that the crosshairs (reticle) are not too thick and consequently obscure the image.

A fixed scope doesn't allow variations in magnification and is considered more reliable, and since it doesn't have multiple lenses, it produces a clearer, brighter image. However, a variable scope, that allows you to adjust the magnification properties, is more suitable for shooters that practice outside of the usual singular circumstances and targets.

In addition, the more expensive the scope is, the higher its power of magnification typically is.

Scope Image Quality 

A well-known brand can guarantee an impeccable design and material, but perhaps a peripheral, mid-priced manufacturer can also use the same components to make a less expensive, but equally productive scope.

Among the most famous scope manufacturers is Leupold, one of the available optics authorities today, alongside Zeiss and Swarovski. The rest of the most renowned companies are Vortex and Nikon, and they all have proved themselves through the use of excellent overall materials and ruggedness, offering a wide variety of rifle scopes for all types of shooters and intentions, and maintain an outstanding reputation.

These tried-and-true optical systems can range from $200 to $3000 per scope, but they rarely disappoint no matter the cost of the optics. Only the myriad of features differs - the more details, the more complex and performant the scope will be.

Build Quality & Durability

Scopes are usually single-piece constructions, preferably made of durable and compact material (usually aluminum) with an attractive film and matte finish. Most of them are in absolute waterproof integrity so they can handle tough situations and the lenses are coated in single or multiple layers. Coatings ensure reduction of glare, better light transmission, and sharper contrast, as well as zero scratching.

The windage and elevation tactical knobs are situated in the middle of the scope tube and serve to adjust the reticle according to the MOA instructions and allow users to listen to the audible clicks to measure precisely. The target turrets are taller knobs with the same function and are better protected with removable caps.

The Bullet Drop Compensator (BDC) is another way to predict the projectile’s trajectory through its ballistic coefficient, the temperature, barrel length, or elevation. It prohibits any aberrations of the bullet and it is a great tactic and tool for target acquisition.  

An important segment of gun-handling and comfort with a scope is having a rather static and constant cheek weld on the "comb" of the stock, for improved accuracy and shooting. With the forgiving eye relief most scopes offer, you can properly adjust the cheek weld and can have confidence while assuming any position. A scope that successfully holds at zero in unexpected situations, also speaks about the prolonged life of the scope and ensures a satisfied client. 

Some elements go into a high-grade scope, making it durable and of unquestionable quality.  The elements on this list are the ones you should be aware of when purchasing a scope.

Mounts 

The mounting hardware of a rifle-scope includes high, medium, and/or low rings and rails that help you elevate and/or move the scope on your rifle back and forth, according to your desires and preferences. Sometimes they are included with the scope, while other times you have to purchase them separately.

Adding weight to a firearm with a scope can help reduce the recoil and hence the potential damage of a heavy rifle, especially if that rifle is being used frequently. So, the mounting is important, not only because a proper mounting guarantees security, but because it can also sharpen the shot. For optimum accuracy, you want it as close to the barrel as possible.

 So, that said, we suggest that you always mount your scope so you don't have to move your head for optimal field of view. Move the scope to your eye, not your eye to the scope, they say.

A four-inch eye relief ensures safe recoil for the shooter and a full field of view. It comes with a BDC 800 reticle, designed for a 100-yard zero on the crosshair - with marks representing all ranges from 200 to 800 yards, making it very useful and helpful. Adjustments on the spot are as easy as can be with the Zero-Reset Turrets and their positive audible "clicks".

It also features a built-in 20 MOA slope and with the Spot On app by Nikon, that is meant to calibrate the scope to fit the ammunition you are using. It also comes with flip-up lens covers to protect the clear glass.

So, the patented ACSS HUD/DMR reticle this scope houses remains 'true' throughout the entire magnification range and hence opens plenty of possibilities for hunters, marksmen, and competitors everywhere.

It has impressed many users, together with its illuminating capacity and common CR2032 3V Lithium coin battery.
