I had a few FTE problems. I moved the ejector over a hair about 1500 rounds ago. No problems since. I now have over 2000 rounds through it (I’m no longer counting, just hurry up and reload the mags!).

Mine hates CCI. Everything else I have loves CCI but my 15-22for whatever reason simply will not run them. Federal Bulk, Federal Auto Match, Federal Lightning, Federal Champion all cycle with very few problems (less than 10 in the last 1500 rounds).
