Description and Specs
The MG7 458 is a compact, light and stout .46-caliber silencer designed for maximum suppression of big bullets. It is perfect for .450 Bushmaster, other .45-caliber variants, and 400 Legend. Ready for extreme full auto, the MG7 is not just a tactical rifle suppressor, it is quite happy on your hunting rifle, too. The lightweight and easy maneuverability make it great in the field.
The MG7 is precision CNC machined from 100% 17-4PH stainless steel, fully welded, and then hardened to the maximum amount. The final result is a suppressor with a hardness of 45-47Rc and a tensile strength of 190,000psi. In other words, it can handle it.
The MG7 and all of Rex Silentium’s rifle suppressors are compatible with industry-standard quick disconnect (QD) mounts. The main thread on the back of the suppressor is 1.375-24.
All silencers require the purchase of a $200 Federal Tax Stamp.
