The Alex Pro Firearms APF 5.56 Pistol 2.0 is an AR-pattern pistol chambered in 5.56 NATO, built with a 10.5-inch barrel and finished in Robin's Egg Blue Cerakote. Its semi-automatic action runs off a nitride M16 bolt carrier group paired with an adjustable gas block, and it comes set up as a braced 30-round pistol rather than a rifle.

The APF 5.56 Pistol 2.0 draws the same praise as other pistols in this class: the compact size makes it easy to store and transport, and the weight stays manageable with the shorter barrel. The Cerakote finish, in this case Robin's Egg Blue, holds up well to handling and range use according to owners who like a finish that stands out from the usual black or FDE.

Ergonomics get good marks too. The Magpul MOE grip and SBA3 brace combination is familiar to anyone who has run other AR-pattern pistols, so there is little learning curve, and the M-Lok handguard has enough real estate for a light and a foregrip without feeling crowded.

Value-wise, buyers see the nitride-coated barrel and bolt carrier group as good inclusions at this price point, since a coated barrel usually costs extra on other builds. The trade-off some mention is that a bright finish like this one is a matter of taste, so resale interest can be narrower than a standard black gun.
