Dead Air Model: Primal 46Cal Rating: .458 Caliber w/ Energies Up To .338 Lapua Length: 7.9″ Weight: 16.5oz Diameter: 1.618″ Materials: 17-4 Stainless Steel Finish: Nitride Thread Insert, High Temp Cerakote Silencer Mount: Ships with 5/8-24 Insert, HUB to P-Series Adapter and TLPack Wrenches Optimized for big caliber high pressure rifles, but adaptable enough for your pistol – and everything in between. Extreme versatility makes it the king of the multi-platform shooting. Direct thread simplicity, quick-attached Keymo, accuracy driven Xeno, pistol boosters, and 3-lug for sub gun fun, are all made possible thanks to our industry standard 1.375″-24 rear threads and our newly engineered HUB to P-Series adapter. To get you started, we’re including a 5/8-24 direct thread insert and the HUB to P-Series adapter. The Primal is ready for Nomad, Wolfman, and Ghost compatible mounts, right out of the box. From 9mm to 45ACP, and 45-70 to .338 Lapua, like a rabid beast the Primal will eat just about anything you give it. If you only want one silencer (to begin with), the Primal is it. Feed it what you want, mount it how you want. Your gun is waiting.
