What To Look For?

The M1A SOCOM 16 's effective range is up to 1000 yards (3-5 MOA shot group) with good optic magnification and good shooting fundamentals.

Magnification

Image Referenced Gearsofguns

Did you know? As a rule of thumb, every 100 yards increase in the distance, you want your optic magnification to increase by 1X.

For the SOCOM 16, a MAX 6 - 8X magnifications are adequate for most engagement distances.

A low power variable optic like the Vortex VIPER PST, Nightforce ATACR 1-8X, and Vortex Razor HD Gen 2 are great because they have the ability to go from 1X to magnified power with just one optic, so you can use one gun for CQB and distance shooting without having to swap out optics.

Another important feature to have for a variable zoom optic is parallax, if you're not sure if you need it please read here to learn more about parallax adjustment

Keep 3.5 - 4" Eye Relief Distances

4" eye relief distance is the most comfortable for magnified scope users. 

The M1A does kick a little bit when a 308 round goes off, so you do want to keep that eye distance from the scope to protect your eye.

Optic Weight

The M1A SOCOM 16 is a decently heavy rifle, and the weight of the optic definitely need to be considered.

A micro style red dot doesn't significantly add perceivable weight to the rifle at all.

However, when mounting an actual scope that weighs 20+ oz will feel different.

Durable Optic Mount

For the guys who want to run red dots, the GG&G Aluminum Scope Mount and the SADLAK Tactical Scope Mount are the two best options.

They let the user mount an optic closer to the eye with decent eye relief distance, and it doesn't interfere with the ejection port.

Add Cheek Riser

It's highly recommended to have a low mount on the M1A, then add cheek riser to the stock.

MOA Dot Size & Reticle

If you're using the M1A with a red dot sight a 1 MOA or 2 MOA dot size is perfect for precision shooting without obscuring the target.

If you're engaging targets further out in the distance, a first focal point reticle is the best because the reticle changes as you adjust the magnification power, so your crosshair zero doesn't change when you zoom in and out.

For close quarter applications such as home defense, plinking on the range and fast action shooting, a micro-size red dot sight like the Holosun HE508T or Aimpoint Micro will get the job done.

For medium range to long-range shooting, a 1-8X magnification low power variable optic with at least 3 - 4" eye relief distance is a good match for the rifle. The Nightforce ATACR 1-8X first focal plane scope is the best out of all.

I hope you have gotten a lot of value out of this article, go out have fun on the range and be safe!
