The Primal is Dead Air’s .45 caliber Rifle Centric yet multi-purpose silencer. Although it is optimized for rifle calibers like .458 Socom, 45-70, 450 Bushmaster, etc. it can accept Dead Air’s SD500 booster assembly making it usable as a handgun silencer, making it the most versatile model in Dead Air’s line-up. It can use direct thread, KeyMo, Xeno, 3-lug, or SD500 (Nielson Device) and it can eat anything from high pressure magnum calibers like .338 Lapua, all the way down to your light duty pistol calibers. Think of it like a crescent wrench. If you could only have one wrench in your whole toolbox, this is it. So, whether you are looking for a great solution for your .458 or 45-70, or just needing a do-all option while you start filling your toolbox with more dedicated models, the Primal has you covered.
