I started with the factory adjustment (fully open) and closed it a half turn per shot, I was also trying to get my scope dialed in at the same time. Each turn made a noticeable difference in recoil and ejection pattern. Once I had a fail to feed I stopped adjusting, but the next 5 shots were good so I gave it one more half turn closed. That ran three shots fine but the next half turn was a FTF so I backed out a half turn and thats where Im at. Every shot after that was good.
Ive heard its best to run dry on adjusting but I run all my ARs with light oil on the bolt face & extractor. Since I was breaking in a new upper and new mags I didnt want to create any issues on first trip out.
The pistol lower Im running had a RRA NM with a Wolff xtra power spring, SB fixed brace & H2 buffer since it usually runs my 7.62x39 10 upper. Good feel and looked like I was getting good primer strikes on the Wolf steel case.
