Dead Air's multi-purpose .46 caliber Primal can handle everything from big-bore, high-pressure rifle cartridges, as well as low-pressure pistol rounds and anything in between. It is one of Dead Air's most adaptable suppressors. It features direct thread simplicity and can work with quick-attach KeyMo, Xeno, pistol boosters, and 3-lug mounts for sub-gun platforms. This is due to the use of 1.375-24 in. rear threads and Dead Air's HUB to P-Series adapter. It comes with a 5/8-24 direct thread mount and the HUB to P-Series adapter. The Primal is ready for Nomad, Wolfman, and Ghost compatible mounts, right out of the box. All silencers require the purchase of a $200 Federal Tax Stamp.
