On the RHS, in front of the chamber where the HG is cut out, when the charging handle cycles, there is an open area where you could get your fingers caught if holding rifle improperly when rifle cycles, sorry if I wasn't clear.
But in all seriousness, given it’s the same cutout and op-rod design (in this area) as the M1, it sounds like no one in the history of both rifles has reported a stuck or injured finger from getting caught in there so I’d say it’s pretty well a non issue.
