Will the Geissele Super Dynamic-Enhanced (SD-E) Trigger make My new M&P15 perform better than it does now? Expert Answer

Yes, the Geissele Super Dynamic AR-10/AR-15 Enhanced Trigger will reduce your overall trigger pull weight to 2.9 - 3.8 pounds. It is also a two-stage trigger which allows you to know exactly when the firing will take place upon pulling the trigger.

Geissele Trigger by Bubba, March 16, 2023
