For a Glock 49 Gen5 MOS, the Trijicon RMR Type 2 is widely considered the best overall optic due to its durability, reliability, and proven track record. Other excellent options include the Holosun HS507C X2 for a good value, the Aimpoint ACRO P-2 for enclosed emitter preference, and the Leupold DeltaPoint Pro for competition shooting.
