Your AR will be fine. The big difference here is that the AR system always has the extractor jump the case rim. On a Glock or other semi auto handgun system, the case rim slides up under the extractor when properly loaded from a magazine. Manually inserting the round into the Glock, XD, 1911, etc. will cause the extractor to jump over the rim and WILL eventually cause problems with extractor spring tension and start failures to extract. As you can see, the systems are set up differently. Manually Load Away.
