Best AR-15 Upgrades to Improve Accuracy in 2025

The AR-15 remains one of the most popular rifle platforms due to its adaptability and reliability. Whether you use your rifle for home defense, training, or recreational shooting, the right upgrades can significantly improve your accuracy and shooting experience.

Here are the top AR-15 upgrades for 2025 that offer meaningful performance improvements.

Enhanced Triggers

A quality trigger is one of the biggest accuracy upgrades you can make. The Geissele SSA-E and LaRue MBT-2S continue to dominate the market for crisp breaks and predictable resets. For shooters on a budget, CMC offers excellent drop-in trigger options that still outperform stock units.

Free-Float Handguards

A free-floating handguard prevents the barrel from being influenced by sling tension or grip pressure. BCM, Aero Precision, and Midwest Industries produce strong, lightweight rails that improve both accuracy and handling.

Red Dots and LPVOs

Optics have become essential for modern AR setups. For close to medium range shooting, the Holosun 510C and EOTech EXPS series are top choices. For versatile distance capability, low-power variable optics such as the Vortex Viper PST Gen II 1-6x offer clarity and speed.

Muzzle Devices

A well-designed muzzle brake or compensator reduces recoil and muzzle rise, improving follow-up shot accuracy. The SureFire WarComp and BCM Gunfighter Comp remain top performers.

Quality Barrels

Barrel quality directly affects precision. Ballistic Advantage, Criterion, and PSA’s Sabre barrels provide excellent accuracy while maintaining reliability.
