Well mistakes happen but this one has put and extended wait oily even further. I ordered a pt&g lapping tool in both ar15 and ar10 and fast forward weeks later I get two ar15 tools. I have all my parts sitting on my bench ready to go. Does anyone have a lapping tool I can use and mail back? I’ll pay shipping both ways and if I mess it up you can have my brand new one. I’m just ready to get this thing together. Plus I’m a huge Auburn fan and I need all the help I can get as far as sympathy right about now
