It looks like a new silencer company has emerged with a strange tubless suppressor design. I stumbled on them while browsing Reddit and noticed they were running a sale to introduce the new SOS-22 rimfire suppressor. It appears that the new company is more or less Veteran owned and is based out of El Paso.
The new suppressor is interesting because of its relatively low entry point and the fact that it only features 3 baffles. Rated for .22 LR, .22 MAG, and .17 HMR on either a rifle or pistol it seems that the SOS-22 checks all the important boxes for a rimfire suppressor. The SOS-22 weighs in at a scant 3.2 ounces thanks largely in part to its simple design and the fact that it is made from 7075 aluminum.
The most striking feature of the SOS-22 is its ability to take the suppressor down without removing the tube. The serialized portion of the suppressor looks to be the section that attaches to the firearm and the three baffled sections thread into the serialized section. With a noise reduction rating of 39-41 dB dry, it seems that they may be onto something. I wouldn’t be able to say for sure until my calibrated ears heard the suppressor back to back with some of the more common designs.
You can learn more about the SOS-22 on the Rebel Silencers website HERE. It appears current MSRP is $99 for individuals while dealers get a nice price break with a $50 cost.
