Best upgrade you can do! - Geissele Single-Stage Precision M4 Curved Bow Trigger

I've had this trigger installed in my M&P 10 and M&P 15 for about 5 years now. So smooth and so crisp. One of the best triggers you can use, especially for longer range shooting or competition. This trigger is not for new shooters or for a battle rifle. The trigger is very light and probably not good to have in pressure situations. Use the two-stage trigger with around 4lbs of pull for those applications.
