Configurations
Modular length — this suppressor can be run at more than one length. The manufacturer does not publish the dimensions of each configuration, so the length above is the only one on record.
Prices are manufacturer's suggested retail (MSRP). What you pay may differ.
Mount interface: 1/2x28 Over-Barrel. Nothing in the catalog attaches to it yet; check with the manufacturer for the hardware it takes.
Manufacturer claim
- Overbarrel design allows for less added length to end of rifle
- Direct thread eliminates need for costly QD muzzle devices and adapters and allows for easy installation
- Strategic serialization placement lessens chances of serial number destruction in case of an alignment issue causing a baffle/end cap strike
- The modular design allows the user to shorten the can when maneuverability ranks higher than suppression.

- Sonicore Suppressors are manufactured in Middletown, CT USA.
- The modular design lets the owner shorten the suppressor by removing baffles; the manufacturer notes that removing baffles decreases sound reduction.
- Integrated stainless steel muzzle brake allows suppressor to continuously tighten itself
- Stainless steel core with gas-disrupting grooves
- Knurled surface for faster heat dissipation and better grip when removing or installing suppressor
- The Paradox OB is a direct thread overbarrel suppressor, with a lightweight and modular design machined from 6026-T9 Aluminum and 303 Stainless Steel, finished with black, non-glare, Mil Spec Hard Coat Anodize.
- The Paradox’s lightweight design is achieved through using lightweight aluminum baffle modules in combination with 303 stainless steel baffle inserts to create a steel “core.” An integrated stainless steel muzzle brake spins gas in a way to continuously tighten the suppressor onto your muzzle.
- Sonicore suppressors are made out of a combination of 6026 T9 aluminum and 303 stainless steel, depending upon the model. All Sonicore suppressors are hardcoat anodized.
- Sonicore offers a limited lifetime warranty. For more details, please consult your owner’s manual or our website.
- The period between cleanings will vary depending on what type of ammunition you are shooting, the type of host firearm, and environmental conditions such as rain or high humidity. We recommend cleaning the suppressor at a minimum after every 1,000-1,500 rounds.
- Reassembly calls for a moisture-resistant, high-temperature anti-seize lubricant on the baffle threads (the manual names Loctite LB-8023) so baffles do not seize together.
- Lightweight design reduces amount of weight hunters carry in the field
- The Paradox is a perfect lightweight and effective option for hunters.
- Minimum barrel length — 5.56/.223: Minimum barrel length of 13.7 inches or greater is recommended.
- Minimum barrel length — .300 BLK Subsonic: Minimum barrel length of 8.5 inches or greater is recommended.
- Minimum barrel length — .300 BLK Supersonic: Minimum barrel length of 8.5 inches or greater is recommended.
- Minimum barrel length — .308 Win: Minimum barrel length of 18 inches or greater is recommended.
- Minimum barrel length — .30-06: Minimum barrel length of 18 inches or greater is recommended.
- Minimum barrel length — .300 WM: Minimum barrel length of 20 inches or greater is recommended.
- The Paradox OB and DT suppressors are meant for use on bolt-action, lever-action, and single shot firearms and as such, we do not have any defined Rate of Fire restrictions.
- We DO NOT recommend using them extensively on semi-auto platforms. The Rekkr DT and OB are more suited for use on those firearms.
- Due to the materials involved in construction, Sonicore Suppressors are not full auto rated.
- Sonicore Suppressors are not rated for FRT use.
- The minimum configuration recommended is the configuration the suppressor comes in from the factory.
- Use of an ultrasonic cleaner is not recommended for any Sonicore suppressor.
- Using a crush washer, peel washer, or anything else that causes misalignment voids the warranty.
- Over-barrel Paradox suppressors require at least 3.5 inches of clear barrel to install properly.
