The M-16A2 is easily one of the most recognizable firearms in history. From being featured in video games to movies to the news, you’ve almost certainly seen one. 

For the last several decades, the M-16 pattern rifle in one form or another has served the U.S. military proudly. While it has been widely replaced with the lighter and more versatile M4, you can still likely find some floating around reserve units and training classes. 

Unfortunately, not everyone can own a genuine M-16A2 due to its famous three-round burst functionality. But now, thanks to Springfield Armory’s SA-16A2, you can at least feel like you’re shooting the real thing, all while enjoying some additional features.

It looks like it belongs in the jungle, doesn’t it?

The aesthetics of the M-16A2 are what draw most people to it these days, but the performance is not something to be overlooked either. After spending the last several weeks with the SA-16A2, I can confidently say it’s not just a mantlepiece to look at. 

Features

As with any rifle, it only takes a quick glance to notice certain features. However, the most apparent features are often not the most impressive, and that sentiment holds true with the SA-16A2.

If only the burst mode worked.

That said, the attention to detail is top-notch, so once you take a closer look at the lower receiver, you’ll see the unique “property of U.S. govt.” and “burst” selector markings. Of course, you can’t actually shoot in three-round bursts (I wish), but these markings help it stay true to the original M-16A2.

The Accutite tensioning system makes sure everything is nice and snug.

Then, once you look even deeper into the lower receiver, there is the Accutite tensioning system that helps eliminate any play between the upper and lower receivers. It’s a nice touch that enhances performance potential and could be easily overlooked if you don’t take the time to examine the rifle. 

Working your way to the front of the rifle, you’ll pass the ribbed handguard that houses an integral aluminum heat shield. Keep in mind, this style of handguard will reduce your accessory options, especially if you’re used to an M-LOK or quad rail handguard.

The bayonet lug and sling swivels are nice touches.

Once you get past the handguard, not only do you have the standard A2 front sight tower, but you’ll also find an integral bayonet lug and sling swivel. Even if you don’t currently have a bayonet to attach, it’s cool to have the ability to!

The entire box of ammo fits inside the stock, minus the actual box, of course!

Finishing up on the opposite end of the rifle, the fixed stock doesn’t just offer superior durability, but also an impressive amount of storage space. Whether you want to store batteries, bullets, or some snacks, you have more than enough room to do so. I was able to fit an entire box of Wolf ammo in the stock, with a little room to spare. 

As you can now see, there is much more than meets the eye with the SA-16A2!

Range Time

I always try to test a wide variety of magazines and ammo when reviewing a gun that’s new to me. Over the course of several range trips, I ran everything from cheap steel-cased Wolf ammo to higher-end Hornady Match ammo, all of which were sent downrange without a hiccup. While I’ve only had the chance to put 360 rounds through it so far, I’m confident that future rounds will perform as reliably.

Regarding magazines, I of course used the included DURAMAG 30-round magazine, but also tested the SA-16A2 with the following:

I’m so accustomed to running PMAGs that I use them more than any others, but the DURAMAGs definitely fit the aesthetic better and run just as well with it.

My third grouping after getting things dialed in.

My first two range trips were indoors, between 20 and 25 yards, primarily to test various types of ammo and magazines. By the end of the first magazine, I had it dialed in and was keeping groupings like the above. Yes, many people are much better shots, but I’m happy with those groupings using iron sights while shooting from a standing position. 

Once I took it outdoors, I had no problems at all hitting every pop can and water bottle within 50-60 yards, which was the farthest I had available to shoot. Again, I was more than happy with the accuracy. I’m eager to take this rifle to the long-distance range soon and really see what it can do. 

Pros & Cons

Pros: 

  • Reliable and accurate
  • Authentic markings true to the M-16A2
  • The Accutite tensioning system provides a secure fit
  • Large storage compartment within the fixed stock
  • Integral bayonet lug
  • Comes with a soft rifle case and a 30-round magazine

Cons:

  • Handguard fitment was slightly inconsistent
  • You’re limited in accessory options (to be expected, though)

Final Thoughts

This rifle has been a blast to shoot…pun intended. It runs like a champ, was accurate out of the box, and gives you a unique nostalgic feeling when shooting, even if you’ve never shot one before! 

It was a welcome change of pace from the typical AR-15s I typically run. Although the primary purpose of the SA-16A2 is to replicate the infamous M-16A2, I would still likely make a few minor upgrades, such as adding an ambidextrous safety and charging handle. Other than that, this rifle would stay exactly how it came!

I’m looking forward to much more range time with the SA-16A2.

You don’t have to be a history buff or veteran to appreciate the SA-16A2. Between its performance and classic aesthetic, it’s hard not to enjoy shooting it. It’s one of those types of rifles that everyone should experience shooting at least once. 

If you find one for a good deal and have the money to spend, I don’t think you’d regret adding one of these to your collection. As always, stay safe, train hard, and have fun.
