Cmc trigger - CMC Triggers AR Lower Assembly Trigger Kit

I got 2?of these trigger systems in the mail and it took about a week for the first one 2 for the second. I’m guessing cause it was right around Christmas time. I dropped it inside of my smith and Wesson M&P and it fit perfectly with no complaints. I went out shooting and shout about 300 rounds it fired smooth throughout the time I was shooting.
