DBX57
Ultra-compact. Dual gas piston. 3 pounds of American-engineered personal defense. The DBX57 redefines what a PDW can be.
Purpose-Built Performance
Dual Gas Piston System
Locked-breech dual gas piston with 4 adjustable positions for reliable cycling across ammo types.
Monolithic Upper
Upper and lower receiver machined from billet 7075 aluminum for maximum rigidity.
AR-15 Compatible
Uses standard AR-15 triggers, grips, safety selectors, and muzzle devices for easy customization.
Sub-16" Footprint
15.25" overall length at just 3 pounds — compact enough for vehicle carry and home defense.
Locked-Breech
Dual Gas Piston
Unlike traditional AR-platform direct impingement, the DBX57 uses a locked-breech dual gas piston system with 4 manually adjustable positions. Both pistons must be synchronized for proper function — giving you precise control over cycling behavior.
Compatible with FN Five-seveN magazines. Many AR-15 parts interchange — triggers, muzzle devices, grips, and safety selectors.
