[QUOTE="victor3ranger, post: 2850657, member: 127035"] The optimal ejection for any AR platform should be at the 4:00 position. When building my AR10 243 it would pull the fired case only about a half inch out of the chamber. So I went into full blown check everything mode. Rings on the bolt-lined up correctly, buffer and spring-good, gas tube was shorter than I thought it should be so I replaced it. Same problem. Checked gas block and all was good. Last piece was the gas port in the barrel. Sure enough the hole was too small. Drilled it out until I got the 4:00 ejection. After that I sighted in and ran her out to 500 yards. 👍 [/QUOTE]
