Description

Ultra-Compact Maneuverability for Specialized Deployments When operating in confined spaces, tight vehicle interiors, or high-density urban environments, standard-length rifles introduce mobility constraints. The DDM4 PDW SBR resolves these challenges by packing high-performance 300 Blackout capabilities into an exceptionally short, fast-handling platform measuring as short as 20.75 inches.

Advanced Barrel & Recoil Architecture

7″ Cold Hammer Forged Barrel: Built around a proprietary Strength-to-Weight (S2W) profile barrel with a 1:7 twist, chrome lining, and heavy phosphate coating. Engineered specifically to stabilize 300 Blackout projectiles and ensure that heavy subsonic loads remain subsonic, maximizing acoustic suppression efficiency.
Maxim Defense CQB Stock & Enhanced Buffer: Features an integrated enhanced buffer system designed to deliver reliable, smooth cycling across both suppressed and unsuppressed operational states while offering quick length-of-pull adjustments.
Linear Compensator & Handguard Real Estate: Equipped with a Daniel Defense linear compensator that directs muzzle blast forward of the shooter. The 6-inch MFR XL flat front rail features M-LOK attachment points for secure, safe support-hand positioning and accessory integration.

Under U.S. law, purchasers must be 21 years of age or older, and transfers require federal NFA paperwork, approval processes, and Class 3 dealer facilitation.
