Description

Note: The item is located abroad. Please note that delivery conditions, shipping times, and/or the purchase process may differ.

The DDM4 300S was designed for those demanding a high-performance, short-barrel rifle chambered in the versatile 300 Blackout cartridge. Built around a 10.3” Strength-to-Weight (S2W) profile barrel, the 300S uses standard 5.56 bolts and magazines to deliver .30 caliber projectiles with greater muzzle energy than comparable 5.56mm platforms. The increasingly popular 300 Blackout cartridge has proven itself to be extremely efficient in short-barrel rifles, yielding superior ballistics over the venerable 7.62x39 cartridge. With a wide variety of factory ammunition made for everything from home defense, target shooting, hunting, suppressed operation, and tactical applications, the 300S is capable of delivering exceptional performance from a compact, fast-handling package.NFA DISCLAIMERThis firearm is a regulated item by the National Firearms Act (NFA). Please check with your local and state municipalities for any further regulatory requirements. It is the buyer’s responsibility to make sure he/she complies with all NFA rules and applicable laws.MATERIALS & CONSTRUCTIONLOWER RECEIVER: Mil-Spec with Enhanced Flared Magazine Well and Rear Receiver QD Swivel Attachment Point.
