(4 out of 5) ATI Milsport AR-15
by from Boise, ID on

This gun is fun and looks great. Only problem I’m having is that after 150 rounds my hammer pin walked out 2mm or so. Almost fell out of the left side on the receiver. The hole for it does not look spec. It was drilled to big or trigger/hammer assembly wasnt installed right. Have yet to take it apart. Hopefully an easy fix with anti locking pins, or fixing the hammer spring. You get what you pay for.
