S&W AR 15 Sport 2 Upgrades: What You Need to Know

If you own an S&W AR 15 Sport 2, chances are you're always looking for ways to improve its performance. Fortunately, there are several upgrades available that can help take your rifle to the next level. In this article, we'll explore some of the best upgrades for the S&W AR 15 Sport 2 and discuss how they can enhance your shooting experience.

Benefits of Upgrading Your S&W AR-15 Sport II

Before delving into specific upgrade options, let's first examine why upgrading your rifle is a good idea in the first place. Here are just a few benefits you may experience after making certain upgrades:

  • Improved accuracy
  • Increased durability
  • Enhanced functionality
  • Personalized feel and appearance
  • Higher resale value

Not all upgrades will provide every benefit listed above, but most will offer at least one or two advantages over stock components.

Best Upgrades for Your S&W AR-15 Sport II

  1. Trigger Upgrade – One of the easiest and most effective upgrades you can make is installing an aftermarket trigger. A better trigger can improve accuracy by reducing pull weight and increasing smoothness.

  2. Optics Upgrade – Adding optics like red dot sights or scopes helps increase accuracy by allowing faster target acquisition and more precise aiming than traditional iron sights alone.

  3. Barrel Upgrade – Replacing your barrel with one made from higher quality materials like stainless steel or chrome-moly can increase durability while potentially improving accuracy through improved consistency in bullet placement shot after shot.

  4. Handguard Upgrade – Updating your handguard with a free-floating model made from lightweight materials like aluminum helps reduce weight while also providing additional attachment points for accessories like lights or lasers.

5.Muzzle Device Upgrade – Swap out that factory muzzle device with something designed specifically to meet your needs whether it be flash suppression or recoil management.

Tips for Choosing Upgrades

When choosing upgrades, it's important to keep a few things in mind. For instance:

  • Consider your needs: Do you need greater accuracy? More durability? Improved ergonomics?
  • Choose quality components: Don't skimp on quality; cheap parts may fail or even damage your rifle.
  • Stick with reputable brands: Do some research and choose upgrades from trusted manufacturers with good reputations.


Upgrading an S&W AR 15 Sport 2 can enhance its performance and functionality while also making it more personalized. By adding high-quality aftermarket components like triggers, optics, barrels, handguards or muzzle devices you can improve the durability and accuracy of your weapon as well as make it lighter weight. Take the time to do some research into specific components before buying them to ensure that they'll meet your needs effectively. With these upgrades installed on your firearm, you'll be better equipped than ever before!


What are some popular upgrades for the S&W AR 15 Sport 2?

The S&W AR-15 Sport 2 is a versatile rifle that can be customized to suit different needs and preferences. Some popular upgrades that you can consider include installing new sights, changing the handguard, adding a muzzle brake or compensator, upgrading the trigger, and installing a new stock.
One of the most recommended upgrades is replacing the standard A2 front sight with an adjustable rear sight or optic for better accuracy at longer distances. You may also want to upgrade your handguard to improve comfort and enhance accessory mounting options.
Another common upgrade is swapping out your stock trigger for one that provides smoother travel and less take-up before breaking. This will result in more precise shots without sacrificing speed.

Should I opt for a free-float or drop-in handguard when upgrading my S&W AR 15 Sport 2?

Choosing between free-float and drop-in handguards can be challenging if you don't know what each option offers. Free-floating handguards provide better accuracy as they eliminate pressure points between barrel and rail while enhancing cooling performance by allowing air circulation around it.
Drop-in units are easier to install since they do not require removing any parts from your weapon; however, they tend not to have as much rigidity under stress like when using bipods or other accessories.

It's all best decided based on personal preference so choose whichever suits you best.

What type of muzzle device should I get?

Muzzle devices play an essential role in reducing recoil and noise levels while improving accuracy by redirecting gases away from shooter/muzzle direction; hence it's worth considering having one installed on your rifle.
The two main types of muzzle devices are compensators/brakes (for reduced recoil) & flash hiders (to reduce visible blast/flame). Depending on user need(s), prioritizing either function over another might lead them towards a specific type.

How can I improve the accuracy of my S&W AR 15 Sport 2?

The AR-15 Sport 2 is known for being an accurate rifle out of the box, but there's always room to improve. An excellent place to start would be with installing a new trigger that has less travel and smoother pull weight.
Swapping out your standard handguard with a free-floating one will also enhance accuracy by providing better consistency in barrel harmonics & pressure points on barrel while reducing weight.
Another option is upgrading your optic/sights system; more precise sighting devices like red dot or low magnification scopes may provide greater precision at longer ranges.

Can I perform upgrades on my S&W AR 15 Sport 2 myself?

Yes, you can definitely upgrade your S&W AR-15 yourself; however, ensure that you have sufficient knowledge about how firearms work before attempting any modifications. Furthermore, it's essential to follow all manufacturer guidelines when changing parts as breaking any rules could lead to safety issues or degrade performance over time.

In conclusion, upgrading an S&W AR-15 Sport II can significantly enhance its capabilities and make it more versatile for different applications. It's always best practice to research thoroughly what changes/modifications are required based on user preferences before starting any project. Be sure only ever utilize high-quality parts from reputable sources as these will guarantee proper functionality without causing damage either short term or long-term down the line!
