The modern home- and in-vehicle defense environment demands compact, reliable platforms that deliver rifle-class performance without sacrificing maneuverability. This review examines a short-barreled, piston-driven design that condenses the SCAR family into a package that’s easy to carry, aim, and maintain in tight spaces.

FN SCAR 15P [FDE] *10-ROUND*

The SCAR 15P brings a proven piston-driven 5.56 NATO platform into a sub-20-inch overall package. At a listed 19.75 inches overall with a chrome-lined, free-floating 7.5-inch barrel and a 10-round magazine restriction in this FDE variant, the 15P is tailored for legal compactness while keeping the SCAR lineage’s ruggedness intact.

Key features and what they mean on the range

The monolithic aluminum receiver carries over from the SCAR family, providing a stable mounting platform for optics and zero retention. Weight is listed at 5.65 pounds—nearly a pound lighter than the SC model—so it’s easier to maneuver without excessive fatigue. The non-reciprocating, dual ambidextrous charging handles and the M1913 Picatinny rails at 3, 6, 9 and 12 o’clock allow fast, intuitive manipulations and accessory mounting for lights, lasers, and short-range optics.

Gas system and reliability

The two-position user-adjustable gas regulator is valuable for tuning the 15P between suppressed and unsuppressed use or to manage different ammunition loads. The piston-driven design keeps the operating system cleaner under sustained fire compared to direct impingement counterparts—an advantage for defensive use where reliability is essential.

Handling, ergonomics, and intended role

At under 20 inches and described by FN as ideal for in-vehicle or in-home defense, the 15P sacrifices a traditional stock to remain out of SBR territory while adding a vertical rear Picatinny rail with a QD sling cup for single-point attachment. That rail placement and the QD point make it simple to transition between carry and deployment in confined spaces. The chrome-lined barrel supports longevity and corrosion resistance for extended service life.

Price is listed at $3,899.99, reflecting the SCAR family’s premium materials and engineering. For those who need a compact, high-quality semi-auto defense platform in the Semi Auto category, this model is worth considering. View product details and pricing
