The PWS BDE556-TI suppressor is a modular, 3D-printed titanium rifle can for 5.56mm from Primary Weapons Systems (PWS part no. BDE556). It ships with removable baffles, so you can set the length and the noise reduction to suit the rifle and the job. The baffles are engineered for low back pressure, which cuts the gas blowback that a suppressed AR sends toward the shooter. A universal 1.375×24 thread pattern lets it work with most suppressor mounts. For an AR-15 owner who wants an adjustable titanium can rather than a fixed-length one, this is the PWS answer.

Key Specifications

• The caliber is 5.56mm, the AR-15 chambering this model is built for.

• The design is modular with removable baffles, so length and noise reduction can be set to preference.
• The baffles are tuned for low back pressure, reducing gas blowback for smoother cycling.
• The thread pattern is a universal 1.375×24, compatible with most suppressor mounts.
• The exterior has a DLC coating, a durable finish that protects against the elements.
