The MG X is a platform for you to get the exact suppressor you want.

Starting with 3 baffles, you tell us how many baffles and what bore diameter you need. We do the rest for you in about a week. Not a one size fits all proposition, we will custom cut your bore to your desired caliber.

From 3 baffles up to 15 or anything in between, you get a custom suppressor done exactly your way. Want a special serial number or logo, just let us know.

Yes! NFA Dealers can order customs too!


Standing on the shoulders of the GEN3 Fidelis Rifle Suppressor, the MG 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.

Ready to take on your wildest host, whether a wildcat, ultra magnum, Weatherby magnum or just a vanilla 30 caliber, the MG can handle whatever punishment you choose. Backed by our lifetime, no bullshit warranty we designed the MG 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 MG 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.
