This is a AR Gold trigger made by American Trigger Corp. This one breaks at 2.5#'s, and the reset travel is extremely short. I have used this trigger in my Tac Ops 3 gun rifle for about 1.5 years now. If you are unfamiliar with this trigger read up on it or try one out before buying. Some will have to be fitted depending on which safety selector is used. I suggest the JP adjustable safety for ease of installation. These sell for $270 new, but I will take $175, or best offer, shipped in the USA. PayPal or MO only. PM or email for more info.
