Owners of the AP51 PDW point to the 7.62x51 chambering in a pistol format as the defining draw. The combination of the short 8.3-inch barrel and the NATO round makes this a polarizing platform, with some finding it a unique large-caliber range piece and others noting that muzzle blast from the threaded barrel is significant without a device attached.

The manual safety and adjustable rear sight get consistent approval. The Picatinny rail is appreciated for accessory flexibility. The Navy-style grip draws more divided reactions, with some finding it comfortable for a large-frame pistol and others preferring aftermarket alternatives.

Value perception depends heavily on what a buyer wants. Those specifically seeking a compact 7.62x51 pistol see it as filling a genuine gap. Others feel the 20+1 capacity is a strong point, but note that the overall size and weight of the AP51 make it impractical outside of range or truck-gun use.
