Terrific trigger upgrade - ALG Defense ACT Advanced Combat Trigger for AR-15/AR-10

This is a fantastic replacement for a gritty stock / OEM trigger (Sig M400 in my case). The polishing and coating on the surfaces was surprisingly good for such an affordable trigger. Two choices for pull weight depending on which of the provided hammer springs you choose (I opted for the heavier - about 6 lbs.). Very crisp feel. I watched video reviews of this and a few other replacement triggers and I’m very happy with my choice. There are of course many terrific products out there but I don’t think you can go wrong at this price.
