ArmaLite M15PDW40 40 S&W Pistol 8.5" 31+1 Glock Mag Compatible

The ArmaLite M15PDW40 delivers pistol-caliber performance in an AR-15 platform, chambered in 40 S&W with Glock magazine compatibility. This personal defense weapon combines the familiar ergonomics of the AR system with the stopping power of a proven law enforcement cartridge. The 8.5-inch barrel provides optimal velocity while maintaining compact dimensions for close-quarters applications.

What Makes This Different

Unlike traditional AR-15s chambered in rifle cartridges, the M15PDW40 utilizes straight blowback operation optimized for pistol ammunition. The Glock magazine compatibility eliminates proprietary magazine concerns while providing access to high-capacity options. Factory Magpul furniture and MBUS flip-up sights come standard, eliminating the need for immediate upgrades that plague budget alternatives.

Key Features

• 40 S&W chambering with straight blowback operation for reliable cycling
• Glock magazine compatibility accepts standard 22-round and extended capacity magazines
• 8.5-inch barrel with muzzle brake reduces recoil and muzzle rise
• Magpul MOE+ grip provides enhanced texture and ergonomics
• Factory MBUS flip-up iron sights with standard sight radius
• Mil-spec buffer tube ready for brace or stock installation

The 40 S&W cartridge delivers 400-500 foot-pounds of energy at the muzzle, providing substantial stopping power for personal protection scenarios. The straight blowback action cycles reliably with both standard pressure and +P ammunition. Law enforcement agencies appreciate the commonality with existing Glock pistol magazines, while civilian users benefit from the widespread availability of 40 S&W ammunition.
