I purchased an AR-Stoner upper receiver lapping tool and finally got around to using it tonight. Fit was tight but not excessively tight. Use plenty of ALG grease before starting. My question is….. “How much material should be removed?” I just tried to even out the high spots. Any advice / direction is greatly appreciated as I have several more uppers I plan to do. TIA. Rick

I did not want to remove that much either. So when I fit it without the abrasive compound I could get a piece of paper on the top left side (facing the upper). After I go close to being flat I switched to the fine compound. I didn’t realize it was off like it was. I checked it more than 6 times during the whole process. 😂
