The multi-purpose .46 caliber Primal. Optimized for big caliber high-pressure rifles, but adaptable for pistols and everything in between. Direct thread simplicity, quick-attach KeyMo, accuracy-driven Xeno, pistol boosters, and 3-lug for subgun fun, are all made possible thanks to the industry-standard 1.375-24 rear threads and the newly engineered HUB to P-Series adapter.
