I've got a Triggertech Diamond AR15 trigger for sale. PVD (black) shoe, flat face, red housing. It's been used to sight-in an AR15, and that's it. Bought it about a month ago. No wear, no scratches, probably less than 75 rounds fired with it.
Purchased for $285, asking $250 shipped to you. I take MO, PP (ff or buyer pays 2.9% fee), or checks.
Feel free to message me for pics or questions.
