Yes. Purchasing solvent traps is legal in all 50 states when used strictly for firearm cleaning and maintenance. No background check or paperwork is required. However, modifying a solvent trap into a suppressor without an approved BATFE Form 1 is a federal offense.
At Freedom Gear, we only sell 100% compliant solvent trap kits and parts — no dimples, no monocore traps, and no illegal machining. Shop with confidence knowing your gear is designed, tested, and shipped legally from the USA.
We began as PreppersDiscount.com over 15 years ago, serving the preparedness and firearm community with reliable gear. Today, as Freedom Gear, we carry forward that same commitment to quality, compliance, and value — giving our customers solvent traps they can trust.
A solvent trap is a firearm cleaning accessory designed to attach directly to a threaded barrel. Instead of making a mess while flushing your bore with cleaning fluid, a solvent trap catches and contains the solvent at the muzzle end of your firearm. This makes routine maintenance cleaner, safer, and more efficient.
Unlike suppressors, solvent traps have no bore hole for a bullet to pass through. They are strictly designed for firearm cleaning and cannot be used to muffle sound without a BATFE-approved Form 1. When purchased from a trusted U.S. supplier like Freedom Gear, you can be confident your kit is 100% compliant and purpose-built for cleaning.

A low-profile 1/2x28 flat adapter that threads directly to the barrel and provides a secure, flush interface for your solvent trap or quick-connect hardware. Ideal for AR-pistol and handgun platforms using 1/2x28.
A robust solid end to close the system and capture solvent safely. Combine with threaded cups for liquid-tight containment during cleaning and transport.
A quick-connect adapter paired with a muzzle device for fast, repeatable setups. The muzzle brake slides into the quick adapter and installs in roughly 1.5 turns — great for users who swap components frequently.
Precision threaded cups that screw together for a liquid-tight seal, creating chambers that contain solvent during bore cleaning. Stack cups to tune capacity and flow.
Heavy-duty steel muzzle brake built to interface with D-sized quick-connect systems. Rugged, repeatable, and ready for frequent install/remove cycles.
Lightweight titanium brake paired with the Viper titanium ring for corrosion resistance and fast changes. A great option where weight savings and quick-connect convenience both matter.
Your solvent trap should match your barrel’s thread pitch for a secure, leak-free fit. The most common standards are 1/2×28 (often seen on many 5.56/9mm platforms) and 5/8×24 (common on .30 cal/.308/7.62 platforms). Always verify your barrel’s thread spec.
The Cupless design uses modular 1″ sections that screw together—no cups needed. On the product page, choose the thread pitch (1/2×28 or 5/8×24) that matches your barrel.

Material affects weight, corrosion resistance, feel, and price. Freedom Gear offers aluminum and titanium options for solvent traps, while our muzzle brakes are available in steel (and select titanium combos) for durability at the muzzle.
The most reliable way to verify your thread size is to check the specifications on your firearm's barrel or consult a qualified gunsmith. For common thread sizes, such as 1/2×28 or 5/8×24, it is usually mentioned in the user manual or product description.
Yes, you can switch between 1/2×28 and 5/8×24 threads if you have the correct adapters. Simply choose the appropriate threaded parts for your firearm's barrel and swap out as needed.
The main difference between D-size and C-size solvent traps is the diameter. D-size is larger and often used for larger calibers like .308, while C-size is more compact and commonly used for smaller calibers and pistols. Both sizes can be threaded with the same adapters to ensure compatibility.
