Short or tall, the MG22 can do it all!


The MG22 was born of the MG series rifle suppressors. 100% hardened 17-4 Stainless Steel (190KSI tensile strength) for extreme duty, and high volume shooting in all rimfire cartridges. No aluminum to damage by either excessive shooting, or lack of cleaning! Designed for up to 9 length configurations, it allows the user to tune the weight, and desired suppression level to their liking.

Clean it or not… it will take it. Go ahead, scrape off the baffles with your pocket knife. The MG22 doesn’t care!

It is built to run and run. A 100% no-fault lifetime warranty comes standard, as with all Rex Silentium products. If you kill it, we fix it, no BS!


Keep it clean, and remember that after cleaning use some ablative gel (petroleum jelly or similar no toxic gel) on all internal parts before reassembly. The wipe can easily be replaced as a repair item by you or a gunsmith.
