- Ignoring Compatibility: Not all parts work with every M&P 15 model. Make sure your chosen upgrade is compatible.
User Experience and Use Cases
How you use your M&P 15 will guide your upgrade choices.
- Target Shooting: If you shoot at paper targets, you might focus on upgrades that improve accuracy, like a new barrel or a match-grade trigger.
