Standing on the shoulders of the GEN3 Honoris Rifle Suppressor, the MG7 pushes the suppression-centric design further. Now in a tubeless embodiment, we have leveraged the years of development and testing to craft a tough, light and above all, quiet suppressor.

The MG7 was designed for more discreet and tactical use. It is a compact, light and stout package for maximum suppression of subsonic rifle, pistol and small case supersonic rifle cartridges. Though, if you wish, you can put it on anything of magnum stature, just don’t expect the sound reduction like its big brother, the MG10 Ultra Rifle Suppressor. Ready for extreme full auto, the MG7 is not just a tactical rifle suppressor, it is quite happy on your hunting rifle too. The light weight and easy maneuverability make it great in the field.

Backed by our lifetime, no bullshit warranty we designed the MG7 to be easily recored should you ever have any problems. The serial number and engraving is at the very back of the suppressor body. This is the safest place in the event of a baffle strike. If you ever damage to the suppressor we can recore it fast and return it to factory new condition in a matter of days.

Precision CNC machined from 100% 17-4PH stainless steel, fully welded then hardened to the max. The final result is a suppressor with a hardness of 45-47Rc and tensile strength of 190,000psi. Go ahead… mag dump, bump fire or swing your selector to full auto. This suppressor is ready to last a lifetime or two or three!

In addition to the design of the suppressor itself, we also made our assembly systems easily adaptable to custom orders. If you need a special bore size for your host firearm or even a special length, we can build it for you. Our manufacturing cells are flexible enough to accommodate one-off custom assemblies. We can even customize your serial number.

The MG7 and all of our rifle suppressors are compatible with industry standard quick disconnect (QD) mounts. The main thread on the back of the suppressor is 1.375-24. There are many options for QD mounts on the market.
