Patrol Base got another Bolster Armouries Onyx variant to present, the Blackout... "The evil twin brother of the Bolster Armouries ONYX, the ONYX Blackout is a radical departure from the usual racy Bolster aesthetic, opting for more covert styling to suit stealthy operators. Meeting the Bolster performance bar with the very best aftermarket upgrades in the business, the Blackout is at the tip of the spear when it comes to custom-built AEGs and nothing else out there can touch it."
