Read their "Legality of Solvent Traps" disclaimer carefully.
JK Armament is selling parts and products for solvent traps.
Solvent traps are a “firearm accessory” as such they can be attached to the end of the barrel, with an adapter, as a cleaning accessory and are not considered as anything other than an accessory because a projectile, or bullet, cannot pass through the tube without modification.
Solvent traps can be purchased legally without a Form 1.
You cannot, however, modify, alter or redesign them into a device for silencing, muffling or diminishing the report of a firearm without first filing and receiving back from BATFE an approved Form 1. Be aware of the restrictions and regulations.
Only after getting the approved Form 1 back can you make any modifications to the product. A crime is committed if you make the alterations before obtaining the tax stamp. Felony alert! Don’t do any alteration or modifications to our products before getting the approved Form 1 back.
JK Armament disclaims any responsibility for your actions if you fail to follow these guidelines or any applicable laws. This includes Federal as well as state, county and municipal laws and regulations.
We also cannot be responsible for any result, consequence, damage or liability following any modifications or work done on our product after purchase. This includes third party liability.
No recommendation or endorsement of any modification, work or alteration to our product is made by these statements. Any such work, alteration and/ or modification is done at the sole risk and liability of the product owner. If you decide to make any modification or alteration to our products, please first read, review and follow all Federal regulations regarding NFA items.
The stated intent of a solvent trap is to catch and trap gun cleaning solvent during bore cleaning operations commonly performed on firearms. Solvent traps do attach to the muzzle of a firearm but do not have any design features intended to allow a bullet to pass through them.
Since as originally manufactured they are not intended to silence, muffle or diminish the report of a portable firearm they are not silencers as defined in 18 U.S.C. 921(a)(24) and thus also are not firearms as defined in 18 U.S.C. 921(a)(3) or 26 U.S.C. 5845(a)(7).
However, if the solvent trapped was redesigned or utilized to assemble a device for silencing, muffling or diminishing the report of a portable firearm or if intent was demonstrated to use the device for silencing, muffling or diminishing the report of a portable firearm, the solvent trap would be classified as a “firearm silencer” as defined in 18 U.S.C. § 921(a)(24) and as a “firearm” as defined in 18 U.S.C. § 921(a)(3)(C) and 26 U.S.C. § 5845(a)(7).
