Upgrade 1: Improve the Trigger
One of the simplest and most effective upgrades for the M&P 15-22 is replacing the factory trigger. The stock trigger is functional but can be heavy and have a lot of creep. By installing a high-quality aftermarket trigger, you can reduce the trigger pull weight and improve the overall shooting experience.

Upgrade 2: Add a Free-Float Handguard
The factory handguard on the M&P 15-22 is functional but can be restrictive when it comes to adding accessories. By installing a free-float handguard, you can create a more versatile rifle that can accommodate a variety of accessories, such as lights, lasers, and scopes.
Free-float handguards are designed to allow the barrel to float freely, which can improve accuracy by reducing barrel pressure and vibration. They also provide a more comfortable shooting experience by allowing you to customize the handguard to fit your needs.

Benefits of Adding a Free-Float Handguard
- Improved accuracy due to reduced barrel pressure and vibration
- Increased versatility with more accessory options
- Enhanced shooting experience with a customizable handguard
Upgrade 3: Install a High-Quality Barrel
The factory barrel on the M&P 15-22 is adequate but can be improved upon. By installing a high-quality aftermarket barrel, you can enhance the accuracy and performance of your rifle.
Aftermarket barrels are designed to provide improved accuracy, durability, and corrosion resistance. They are often made with high-quality materials, such as stainless steel or chrome-moly, and feature advanced rifling designs that improve bullet stabilization.
Benefits of Upgrading the Barrel
- Improved accuracy due to advanced rifling designs and high-quality materials
- Enhanced durability and corrosion resistance
- Increased confidence in your shooting abilities
Upgrade 4: Add a High-Quality Optic
A high-quality optic can greatly enhance the shooting experience and improve accuracy. By installing a scope or red dot sight, you can quickly and accurately engage targets at various distances.
There are many options available, including scopes from companies like Leupold, Nikon, and Vortex, and red dot sights from companies like Aimpoint and Holosun. When choosing an optic, consider the type of shooting you'll be doing, the distance to your targets, and the level of magnification you need.

Benefits of Adding a High-Quality Optic
- Improved accuracy due to enhanced targeting capabilities
- Enhanced shooting experience with faster target acquisition
- Increased confidence in your shooting abilities
Upgrade 5: Install a Muzzle Brake
A muzzle brake can greatly reduce recoil and muzzle rise, making it easier to control the rifle during rapid fire. By installing a muzzle brake, you can improve the overall shooting experience and reduce fatigue.
There are many options available, including muzzle brakes from companies like SilencerCo, AAC, and SureFire. When choosing a muzzle brake, consider the type of shooting you'll be doing, the level of recoil reduction you need, and the overall design of the brake.
