Glock .40 S&W 8.5" 32-Round Rifle

The ArmaLite M15PDW40 M-15 PDW 40 S&W compact rifle is purpose-built for operators and tactical professionals who prioritize maneuverability without sacrificing firepower. Chambered in .40 S&W with a 31+1 round capacity using Glock-compatible magazines, the M15PDW40 delivers the ballistic advantage of a centerfire cartridge in a package small enough for vehicle carry, CQB environments, and specialized duty roles. The 8.5-inch barrel strikes a practical balance between velocity retention and overall length—short enough for rapid target acquisition in confined spaces, long enough to optimize .40 S&W performance. At 8.9 pounds unloaded, this rifle remains manageable during extended operations without the bulk of full-size platforms.

Field-proven features maximize operational efficiency. The muzzle brake reduces recoil rise and improves tracking between rounds—critical for rapid accuracy. Magpul MOE+ grip and furniture provide ergonomic consistency with weapons systems operators already train with, reducing the cognitive load of platform transitions. Ambidextrous charging handle and safety selector ensure both left- and right-handed shooters maintain the same speed and control. MBUS flip-up sights deliver co-witness height with red-dot platforms, offering a no-battery backup while leaving the upper receiver open for optional optics. The serviceable pistol buffer tube (without brace) allows customization and fits standard mil-spec components, while the M-LOK handguard accepts tactical rails and accessories at multiple points. All controls and components are designed for gloved manipulation and rapid reconfiguration.

Law enforcement tactical teams, firearms instructors, and serious civilian shooters select the M15PDW40 for applications where a rifle-caliber round matters but a standard rifle footprint does not. Close-quarters battle, vehicle interdiction, armored security details, and precision room-clearing operations all favor compact, powerful platforms with immediate handling. The .40 S&W offers proven stopping power at intermediate ranges while reducing overpenetration risk in environments where precision matters. Glock magazine compatibility streamlines logistics—standard law enforcement duty ammunition and magazines work directly in this system.

The compact rifle segment has matured significantly over the past decade, with designs now refined for serious duty use rather than novelty appeal. The ArmaLite M15PDW40 represents the upper end of execution—quality parts assembly, proven ergonomic foundation (AR platform modularity), and genuine attention to the feedback of end users. The .40 S&W in a dedicated rifle platform remains relatively uncommon, making this model distinct for agencies and operators already committed to that cartridge ecosystem.
