I am looking for two 3 lug adapters for Colt 9mm barrels. The threads are 1/2X36. I would also like one 3 lug adapter for 1/2X28 thread. Please let me know what you have and how much you want for it. I have 7.62X39, 5.56X45, 9mm, and .22lr stuff to trade, if you are interested. The email button is best to contact me.
