Description
There are lightweight rimfire cans, and then there is the Pipsqueak 22. At 1.5 ounces and 3.5 inches long, this thing weighs less than most pistol magazines, so it disappears on the end of your barrel. That matters more than people think. A lot of suppressors make a 22 pistol feel nose heavy and throw off the balance of a lightweight rifle. Hang this one on a Ruger 10/22 or a Mark IV and the gun still handles like the suppressor is not even there. This version comes dressed in an Olive Drab Cerakote finish that pairs nicely with just about any field or hunting setup.
How the Pipsqueak 22 Stays So Light
Anechoic machines the body from aerospace grade 7075-T6 aluminum, then adds a Grade 5 titanium thread insert where it counts. That titanium mount is a smart touch, since all-aluminum cans are known for carbon lock and galled threads after a few range trips. Here you get aluminum weight savings with titanium durability at the wear point. It is also fully user serviceable, and the included wrenches make teardown and cleaning straightforward, which is a big deal with dirty rimfire ammo.
One Can for Your Whole Rimfire Lineup
The Pipsqueak 22 is rated for 22 LR, 22 WMR, and 17 HMR, and the fixed 1/2×28 direct thread mount fits nearly every threaded rimfire rifle and pistol out there. It even carries a full auto rating up to 100 rounds of 22 LR and a rapid fire rating of 25 rounds with 22 Mag, so casual mag dumps at the range are on the table. Keep in mind it is a rimfire can only, so no 223 or 5.56 hosts.
Small Can, Real Suppression
Do not assume the compact size means it gives up much at the ear. Side by side comparisons against larger rimfire suppressors on identical rifles have shown the difference is barely noticeable outdoors. If you want your 22 quiet without changing how it carries, points, or balances, this little can from Anechoic is about as easy a choice as they come.

Frequently Asked Questions
What firearms will the Pipsqueak 22 fit?
It uses a fixed 1/2×28 direct thread mount, which is the standard thread pattern on nearly every threaded rimfire rifle and pistol made today. Popular hosts include the Ruger 10/22, Ruger Mark series pistols, and threaded bolt guns in 22 LR, 22 WMR, or 17 HMR. Just remember it is rimfire only and not rated for 223 or 5.56.
How quiet is a suppressor this small?
Better than the size suggests. In side by side range comparisons against larger rimfire cans on identical rifles, the difference at the shooter's ear was barely noticeable outdoors. Pair it with subsonic 22 LR and you get genuinely quiet shooting from a can that weighs about as much as a few sheets of paper.
Can I take the Anechoic Pipsqueak 22 apart to clean it?
Yes, it is fully user serviceable and ships with the wrenches needed for disassembly. That matters with rimfire suppressors since 22 LR ammo is dirty and lead and carbon build up fast. Regular cleaning keeps it performing well for the long haul.
Is the Pipsqueak 22 rated for rapid fire or full auto?
It carries a full auto rating up to 100 rounds of 22 LR and a rapid fire rating of 25 rounds with 22 Mag. Round counts should be reduced on shorter barrels, and the manufacturer advises keeping the can under 400 degrees Fahrenheit. For typical plinking and hunting use, that is plenty of headroom.
