Order Now For 10% Off | Ends October 31st! This month Armory Den is donating to the Hope For the Warriors with contributions through October.

The design and engineering of our 304 Stainless Steel Adaptive Solvent Trap Kit is identical to the Aluminum and Titanium 1.57″OD AST kits, but naturally heavier due to the material. This kit includes a 1/2×28” and 5/8×24” thread mount, one sealed end cap,  2.5” tube extension, 8 adaptive storage cups.

Standardized 1.1875-24 TPI Adapter Included: This item converts a thread of 1.375-24 TPI to a 1.1875-24 TPI.  This adapter attaches to the industry standard 1.375-24″ TPI tube thread. A setup for those that have a need to adapt to various industry muzzle adapters, for purposes such as a quick detach setup to simplify the connection and disconnection of the solvent trap for streamlined cleaning!

Solid from website to my hand, top shelf As I shopped for the product, I kept returning to the Den website. Descriptions are clear, lots of good information, very good value. Ordering is simple, terms are straightforward. I had special shipping instructions, followed perfectly. Secure packaging. The trap is well machined, fits tight, and is nicely finished. The hand-feel has heft and is of quality. Extra care at every step. Thanks.

They did the right thing! Let me just start with Thank you Armory Den! What exceptional customer service! Their response time to emails, is faster response time then the police department has where I live for 911 calls lol j/k. Seriously, they answered me on Sunday, morning and afternoon. No company does that! Also, I asked about a part I thought came with my order. I was ready to pay for it, nope, they sent them to me for free, and shipped on a Sunday! No one does that! I’m a customer for life! I even canceled an order I had with another company, just so I can buy from ARMORY DEN! My business motto is “always do the right thing l, no matter what” they obviously follow it also!

This company is the real deal I was a little skeptical about ordering honestly. I hadn't heard much about armory den and could only find good reviews lol. But I took a chance and put through an order. Everything arrived as described and is awesome. Be aware that you may receive multiple shipments based on what you order. These guys respond fast and from what i have seen, produce quality products. They have my future business. I've put up similar reviews and given a recommendation on their FB page.

Great customer service I think of all the online retailers I have dealt with, these guys are truly set up for great customer service. They have gone way out of their way to make this buying experience more than great. Quick response to the needs of customers are rare today. Thank you for doing what other online realtors have just forgot to do. Taking care of the customer.

304 Stainless Steel


A solvent trap is a firearm cleaning system that is designed to capture (or “trap”) cleaning solvent during the bore cleaning process, in order to transport and dispose of it efficiently, safely and in an environmentally friendly manner. Solvent traps attach to a firearms muzzle and feature cups, also referred to as dry storage cups, dividers, among other interchangeable names. Solvent traps are designed in a way that ensures a bullet may not pass through them.

The BATF defines a solvent trap as a “firearm cleaning accessory”, but to make certain that a solvent trap remains within the BATF’s “firearm cleaning accessory” definition, it should be clear that they are constructed to serve such a purpose.  Our solvent traps are designed and manufactured to serve one primary purpose, which is as a firearm cleaning system. We do not endorse, support or recommend using our solvent traps or solvent trap dry storage cups to silence, muffle or diminish the report of a firearm. Rather than selling our solvent trap tubes, dry storage cups and end caps separately, our solvent trap cleaning kits include all parts needed, and they are sold for cleaning purposes only. Modifying our products and/or using them for any other uses are not recommended or endorsed by Armory Den.

Solvent traps can be purchased legally without a Form 1. However, you cannot alter, modify, or redesign them into a device for muffling, silencing, or diminishing the report of a firearm without first, paying the NFA Mandated $200 Tax Stamp (if applicable) and receiving back an approved From 1 from the BATFE. Please be aware of the restrictions and regulations and those within the states you reside. 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.

Foreign Purchase Warning for Consumers

As a consumer in the solvent trap market, it’s important to ask the right questions prior to purchasing online. You should understand why certain US solvent trap companies have been shut down, why others still operate, and which specific companies will continue to operate. You should also understand why those who purchase solvent traps overseas are visited by the ATF and receive a letter from the U.S government regarding illegal products they have ordered online from companies they believed to be legitimate. These questions are far more important, as opposed to saving a few dollars by ordering illegal solvent traps that are also made from weak diluted metal composites.

Illegal foreign solvent traps are permeating the US market, and a majority of them are illegal. These foreign solvent traps are not vetted, nor do these companies have U.S attorneys or former Special Agents and specialists to ensure legal solvent traps are being engineered for legal U.S purchase. These same foreign solvent traps contain inferior and diluted metals, and poor finishes. More importantly, they contain clear and unclear characteristics deemed to show ‘constructive intent’ by regulators. This is very important to understand when you shop around for solvent trap solutions.

Even legitimate U.S sources such as firearm and non-firearm auction sites, as well as broker and listing sites are littered with illegal foreign solvent traps sold by their subscribers who list them on these outlets. Even Armory Den products have been cloned and listed on these same reputable auction and listing sites. We process complaints to protect consumers, but it is extremely difficult to get timely a resolution and/or response. The reason foreign companies choose to clone our products with weak materials and illegal versions, are because we dominate search engines. **Armory Den only sells products via our website**

Armory Den is one of the most reputable and trusted solvent trap cleaning solution companies listed on Page 1 of Google, Bing, Yahoo and DuckDuckGo. Any company, counterfeiter, or scammer can easily create a Paid Advertisement in a matter of seconds, but being listed on Page 1 of organic search results takes time, reputability and long-term investment. Companies with long-term views invest in such a thing. Google and other prominent and respected search engines will only show the most reputable companies who sell products consumers can trust, as well as relevant and reliable information.

Foreign companies will advertise their products as legal, simply because they do not know any better, and because they are not legally bound to U.S laws. To them you are a sale and a number on their analytics reports. If you happen to receive one of their illegal solvent traps, you may end up with a knock at your door from the ATF, and/or receive a letter from the U.S government – A risk and headache you don’t want!

Meanwhile, the foreign company who sold you the product will have zero repercussion. Overseas sales are monitored by the ATF through Customs, whether you believe it or not. There are also companies in the U.S who sell illegal solvent traps, simply because they do not understand what makes a solvent trap legal vs. illegal. These companies will eventually be shut down, and you don’t want to be listed as one of their customers!

This information is to help our consumers make a well-informed decision prior to purchasing a solvent trap online.
