The FN Reflex MRD in FDE gets positive reviews for its compact size, light weight, and optic-ready capability. The red dot compatibility is the most-discussed feature, with shooters who use micro red dots finding the mounting system straightforward. Ergonomics and grip feel are generally rated well, though a few users with larger hands find the grip slightly short.

Reliability and accuracy are described as solid, with most owners reporting clean function from the start. Some mention a short break-in period or ammo sensitivity. Trigger feel divides opinion: some like the consistent SAO pull, while others prefer a crisper break. The FDE finish draws mostly positive comments on aesthetics. Price comparisons to competitors are common in discussions, with opinions split on whether the value proposition is strong.
