Daniel Defense DDM4 Custom Build SBR, 5.56 NATO, 11.5" Barrel, 32rd, M-LOK

The Daniel Defense DDM4 Custom Build SBR is a 5.56 NATO short-barreled rifle assembled around a DDM4 lower receiver and an 11.5-inch, medium-profile barrel with a 1:7 twist. Daniel Defense stock, pistol grip, foregrip and charging handle establish the component lineup, while fixed front and rear sights give the build a distinctive carbine configuration.

This build pairs a DD4 7.0 M-LOK handguard with a fixed front-post gas block featuring a bayonet lug. An A2 birdcage flash hider completes the muzzle, and a Daniel Defense A1.5 fixed rear sight uses Rock & Lock mounting. One 32-round magazine is included.

Shop the Daniel Defense DDM4 Custom Build SBR at BattleHawk Armory for this specialized combination of DD components, fixed sights and an 11.5-inch barrel.

11.5-Inch Medium-Profile Barrel

The barrel measures 11.5 inches and is chambered in 5.56 NATO. Its medium profile identifies the barrel contour, while the 1:7 twist means the rifling completes one full turn in seven inches. These defining specifications give the custom build its compact SBR proportions.

An A2 birdcage flash hider sits at the muzzle. Its familiar slotted configuration complements the fixed front-sight layout and completes the rifle's traditional carbine appearance. The barrel length, medium contour and A2 muzzle device are central to the identity of this particular build.

DDM4 Lower and Daniel Defense Furniture

The DDM4 lower receiver includes an ambidextrous safety selector, providing selector access from either side. Daniel Defense supplies the stock, pistol grip and foregrip, giving the rifle branded components at its primary contact points. The build also includes a Daniel Defense charging handle.

The shoulder stock and 11.5-inch barrel form the short-barreled rifle configuration. The foregrip supplies a dedicated forward hand contact point, while the pistol grip and stock complete the rear furniture. Together, these parts create a coordinated DD component package.

DD4 7.0 M-LOK Handguard

The DD4 7.0 handguard provides a 7-inch M-LOK fore-end. Its M-LOK interface supports compatible accessories at the available attachment slots, allowing accessory selection to suit the space and mounting requirements of the handguard. The fore-end works alongside the build's fixed front-post gas-block arrangement.

Fixed Front Sight and A1.5 Rear Sight

The front sight is integrated with the fixed front-post gas block, which also includes a bayonet lug. At the rear, the Daniel Defense A1.5 sight provides a fixed sighting reference and uses the Rock & Lock mounting system. This front-and-rear combination supplies a complete iron-sight arrangement.

Fixed sights remain upright as part of the rifle's configuration. Their visible profile is a key feature of this custom build, giving shoppers who prefer a traditional carbine sight layout a clearly defined option.
