The T97 Gen1 likes some mags better than others, but once I found the ones it likes, I've put several thousand rounds through my Gen 1 without malfunction. If you're really worried, it literally tells you what year they were made in the serial number prefix. I have a 2015 and the issues were sorted out by then. There's rail adaptors you can plug into the carry handle and you can cram MAGPUL MOE rail sections into the handguard vents if you want a light. You can make it work.
