A slightly less than two-ounce, 3D-printed titanium suppressor from a Minnesota startup posted the lowest sound numbers of any .22 Long Rifle can tested at the 2025 Thunder Beast Arms Silencer Summit, the latter acting as something like an independent referee for the suppressor industry.
Made by Off Grid Suppressors of Shevlin, Minnesota, the Scorpous .22 LR measured 115.4 dBA at the muzzle and 118.73 dBA at the shooter’s ear on a pistol host—the quietest result in the rimfire category at the August 2025 event in Cheyenne, Wyoming. The Summit brings competing manufacturers to the same facility to shoot the same hosts with the same ammunition while TBAC operates the measurement equipment and publishes the raw data. Manufacturers can’t pick their own numbers, which is why the rankings have become a reference point for buyers.
The Scorpius isn’t machined from bar stock or stacked from individual baffles; the entire internal structure is grown in a single piece on a metal 3D printer using grade 5 titanium. That manufacturing approach lets the designers build internal geometries that would be difficult or impossible to cut on a lathe. Second, at 1.95 ounces and five inches long, it’s light enough that it doesn’t noticeably change the balance of a host pistol or rifle—a real consideration on small rimfire guns where a four- or five-ounce can hangs off the muzzle like a brick.
As for the tradeoff, it’s the fact the Scorpius is sealed. There are no take-apart baffles to clean, which is the standard approach on many rimfire cans because .22 LR is famously dirty ammunition. Off Grid’s answer is that owners drop the whole suppressor in an ultrasonic cleaner or a chemical bath instead of disassembling it. Whether that holds up over thousands of rounds of lead and wax fouling is something the long-term market will have to answer.
Off Grid's Scorpius suppressor is rated for .22 LR, .22 WMR, .17 HMR and 5.7x28 mm, uses a 1/2x28 direct-thread mount and carries an MSRP of $469.99. It ships with a lifetime warranty.
Something else to note: additive manufacturing has been quietly reshaping a category that spent decades dominated by traditional machining. Several of the top finishers across categories at the 2025 TBAC Silencer Summit were 3D-printed designs, and a startup with a printer and good engineers can now show up with a suppressor and beat companies with decades of history—provided the numbers hold up under someone else’s microphones.
