When I think about the M16A2 I think of the U.S. military\u2019s last battle rifle. A rifle that evolved from jungle combat. A rifle in High Power competition that can tag a target at 200 to 600 yards if you do your part. It\u2019s a rifle design that lasted from the mid-1980 to early 2000s. Pals my age remember the rifles fondly as a milestone in their lives. The Springfield Armory SA-16A2 brought back a lot of memories. My iron-sight shooting may be a tad rusty, but keeping them all in the black with this black rifle is something every rifle shooter should add to their bucket list. It\u2019s not just a box to check and go on to the next. After shooting this rifle, you will want to run more. It\u2019s just that type of rifle.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-the-m16a2-is-old-school-not-outclassed\"><strong>The M16A2 Is Old School, Not Outclassed<\/strong><\/h2>\n\n\n\n<p>You might just yawn at the M16A2 as just another old rifle design. It helps if you know your history. There was a time when all AR15s looked like the M16A2. The era of the M16A2 was a certain generation\u2019s battle rifle. It is our rifle, and I like to think of it as not old or dated, just not new anymore, because it is still a capable firearm.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"762\" height=\"400\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/m16a1-in-vietnam.jpg\" alt=\"M16A1 rifle used in Vietnam War with triangular handguard and duck bill muzzle device\" class=\"wp-image-237192\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/m16a1-in-vietnam.jpg 762w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/m16a1-in-vietnam-400x210.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/m16a1-in-vietnam-150x79.jpg 150w\" sizes=\"(max-width: 762px) 100vw, 762px\" \/><figcaption class=\"wp-element-caption\">The M16A1 was used extensively during the Vietnam War. Note the triangular handguard and duck bill muzzle device. Courtesy NARA.<\/figcaption><\/figure>\n\n\n\n<p>Just like the M1 Garand, M1 Carbine, and M14, the M16A2, in the guise of the SA-16A2, is a piece of our military history. If you are familiar with more modern AR15 carbines, you will know the SA-16A2 intuitively. You\u2019ll understand how modern M-LOK rails transformed the 16A2, making it easy to attach accessories. No duct tape or zip ties required on modern guns. What I like best about the 16A2 is the rifle-length gas system. It is smooth cycling, easy on the shoulder, and a big reason this old-school 5.56 NATO rifle still has a pulse. Mid-length gas systems are a one size fits all solution to modern AR15s with shorter barrels. You need to feel the 16A2 at the range. You need to handle the length of the 16A2. You need the M16A2 as a reference point in modern rifle design.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-m16a1-vs-m16a2-the-changes-that-built-the-sa-16a2\"><strong>M16A1 vs M16A2: The Changes That Built the SA-16A2<\/strong><\/h2>\n\n\n\n<p>It was 1979 when the Marines requested changes to the M16A1. They liked the M16A1 and used it extensively in combat during the Vietnam War. However, they thought it could be better. Let\u2019s take it feature by feature.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"890\" height=\"608\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/m16a2-training.avif\" alt=\"Marine training with M16A2 rifle that inspired the Springfield Armory SA-16A2\" class=\"wp-image-237193\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/m16a2-training.avif 890w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/m16a2-training-400x273.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/m16a2-training-150x102.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/m16a2-training-768x525.jpg 768w\" sizes=\"(max-width: 890px) 100vw, 890px\" \/><figcaption class=\"wp-element-caption\">This Marine is training with the M16A2, which was an improvement over the previous M16A1. Courtesy NARA.<\/figcaption><\/figure>\n\n\n\n<p><strong>M16A1 Barrels vs M16A2 Barrels:<\/strong> The A1 had a 20-inch barrel but with a 1:12-inch twist, which worked well with lighter, 55-gr. bullets like M193 ball ammo, but can\u2019t really stabilize heavier bullets. The A2 barrel is also 20 inches long but has a 1:7-inch twist rate to better stabilize the heavier, longer bullets. The barrel contour of the A2 is also beefed up forward of the handguard, but under the handguard the barrel diameter is exactly the same as the A1 so an M203 grenade launcher can be attached.<\/p>\n\n\n\n<p><strong>M16A1 Muzzle Devices vs M16A2 Muzzle Devices:<\/strong> The M16A1 used a three-prong flash hider commonly referred to as a \u201cduck bill,\u201d which easily snagged on the vegetation in a jungle environment. The M16A2 received a new A2 flash hider nicknamed a \u201cbird cage,\u201d which is enclosed on the front edge. Open side slots are located on the top. There are no slots on the bottom, which transformed the muzzle device into a dual-purpose device that acts as a flash hider and compensator. No slots on the bottom also meant no debris is blasted up when shooting prone.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0181-1-1024x768.jpg\" alt=\"Springfield Armory SA-16A2 muzzle with M16A2 bird cage flash hider and heavier barrel profile\" class=\"wp-image-237197\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0181-1-1024x768.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0181-1-400x300.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0181-1-150x113.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0181-1-768x576.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0181-1.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">The forward section of barrel on the M16A2\/SA-16A2 was heavier than the M16A1.

Not only did the handle allow the rifle to be easily carried, it housed the rear sight. The configuration of the front and rear sight on the M16A2 allows for adjustments to windage and elevation, unlike the earlier M16A1. The rear sight on the M16A2 is fully adjustable with click adjustments for both windage and elevation from 300 to 800 meters. The aperture also has two settings; the small aperture is for daylight shooting, and the large aperture for low-light scenarios. The M16A2 also used a four position adjustable post with a flat face for elevation adjustments. The M16A1 featured a five-setting round post. The M16A1 front sight could create an aberration in certain light causing groups to be off center.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0184-1024x768.jpg\" alt=\"Springfield Armory SA-16A2 front sight post with four position adjustment\" class=\"wp-image-237199\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0184-1024x768.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0184-400x300.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0184-150x113.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0184-768x576.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0184.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">The M16A2\/SA-16A2 uses a four position adjustable post with a flat face for elevation adjustments.<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"797\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0186-1024x797.jpg\" alt=\"Springfield Armory SA-16A2 rear adjustable aperture sight with 300 to 800 meter settings\" class=\"wp-image-237201\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0186-1024x797.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0186-385x300.jpg 385w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0186-150x117.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0186-768x598.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0186.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">The rear sight on the M16A2\/SA-16A2 is fully adjustable with click adjustments for both windage and elevation from 300 to 800 meters.<\/figcaption><\/figure>\n\n\n\n<p><strong>M16A1 Stock vs M16A2 Stock:<\/strong> The length of pull on M16A1 stocks was too short and the relatively smooth butt pad had a reputation for slipping out of your shoulder pocket.

The round handguard on the M16A2 was made of a stronger polymer and is symmetrical and can be used for a top or bottom half.

The barrel has a 1:7 inch twist rate so it should play nice with a range of bullet weights. My range bag doubled as a rest and I used a toe bag. I like shooting aperture style sights and found the SA-16A2 easy to shoot. The trigger broke at a consistent 6 pounds, which made me work for my groups.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"768\" height=\"1024\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0009-1-768x1024.jpg\" alt=\"Springfield Armory SA-16A2 100-yard target with Hornady Steel Match 55-grain HP ammo\" class=\"wp-image-237208\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0009-1-768x1024.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0009-1-225x300.jpg 225w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0009-1-113x150.jpg 113w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2026\/05\/springfield-armory-sa-16a2-review-IMG_0009-1.jpg 900w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><figcaption class=\"wp-element-caption\">Average 5-shot group at 100 yards with Hornady Steel Match 55-grain HP bullets.<\/figcaption><\/figure>\n\n\n\n<p>The best 5-shot group at 100 yards was with inexpensive Hornady Steel Match loaded with a 55-grain HP bullet at 1.36 inches; average was 1.66 inches.

Recoil was mild with none of that fast slappy cycling of a carbine length gas system. There is a definite difference in recoil even with mid-length gas systems. The two features I missed the most were an oversized charging handle and an ambidextrous selector.
