  1. I use the CMC 3.5# flat faced bow trigger. Minimal reset and drop in with hardly any adjustment required.

  2. Trigger Tech is better than any of these. Why are they not in the mix? Typical biased, paid, advertising at best. I recently studied and have bought several triggers, none on this list but 4 other brands, and Trigger Tech with their roller technology is ridiculously smooth and so superior to these old designs, they really cannot be compared fairly. All these others are old gritty mechanical friction based tech compared to them. You should do an article on the design differences and no one would buy any of these old designs ever again unless they were in the proper sub $70 price range, which most of these are not anywhere close to priced properly now.

  3. Rise armament Folds of Honor Nibx coated is a outstanding trigger for the money if you can find it. The POF mentioned above works great in lowers with oversized trigger housings and cold weather gloves and it fits tight no slop. Not mentioned is Hyperfire , I’ve tried their mil spec, 3gun, and Eclipse all are impressive with the Eclipse being phenomenal that baby will never give you a light primer strike.

  4. Hello, I would like to build an AR-15 For sport shooting can someone send me a list of all the parts I will need. Thanks
