1/2x28 Solvent Trap

1/2x28 Solvent Trap, The Legality of Fuel Filter Solvent Traps, How and What to Buy.

Many firearm owners have learned that 1/2×28 solvent traps have the same thread pitch size as many automotive fuel filters. A 1/2×28″ solvent trap is the thread pitch on a firearm cleaning kit’s thread mount that is intended to connect to the firearm barrel that shares this thread pitch, for cleaning.
5/8×24″ and 1/2×28″ thread pitches are the most common for American firearm barrels: From .30 Caliber setups, such as 6.5 Creedmoors, .308s, 300 Blackouts to 9mms, 5.56 NATO/.223 (AR15s) and .22LRs, and more. We would venture to say that 60 to 70% of American firearm calibers using a threaded barrel, use these two aforementioned thread pitches.

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.

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!

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.

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.

Many Firearm Owners Purchase these Auto Parts to Save Money

Many firearm owners purchase these auto parts to save money, with the intent of converting them into an unregistered Class III item, without going through the appropriate channels. This act has attracted investigative attention by the ATF/NFA, which has fueled further disproportionate attention to the use of solvent traps, even the legal and intended use has become hindered. You’re probably wondering, “aren’t solvent traps legal”?…
Yes, they absolutely are! But if one’s intention is to modify a solvent trap in order to quiet or dampen a firearm’s report, this first requires an approved Form 1 NFA Tax Stamp from the BATFE/NFA, which will register the item to a serial number selected by the applicant on the Form 1 application. Once this approved Form 1 Tax Stamp and the associated serial number come back, one can bring the item to a company, FFL 7 Class 2 SOT to have the number engraved and other modifications completed. 
Or, the applicant can do the modifications themselves after receiving the approved Form 1 and Tax Stamp back from the aforementioned channels. Not only is this process 100% legal, it is laid out, and constantly improved through innovation (i.e. E-File System) by the ATF/NFA.

The Difference Between a Solvent Trap and Auto Oil Filter…

Oil filters are used to extract pollutants from a car’s engine, pollutants that gather over time. Pure auto oil is vital because it could become saturated. Small, hard particles can wear surfaces in the engine if the oil is left unfiltered for some time. You can see how there are similarities between fuel filters and firearm solvent traps and why savvy firearm owners have purchased fuel filters in the past. Most have purchased car fuel filters because there were simply not many viable options nor information online or in the general market for them to use.
1/2x28 Solvent Trap
The auto part is solely made for use with automobiles. They’re not meant to be a firearm cleaning accessory! Sure they can be made to work, but wouldn’t it be best to clean your firearm and trap residual solvent with a part made specifically for that item and need? Some auto parts purchased to be solvent traps are Napa parts, Napa Freeze Plugs, Wix Fuel Filters, and other fuel filters, all items the ATF has cracked down on tremendously due to previous illicit uses by individuals not properly educated on the legalities.

Avoiding Legal Issues When Cleaning your Firearms with a Solvent Trap

Solvent traps are used to clean firearms and trap solvent. However, because anyone can alter solvent traps to operate as unregistered Gun Control Act of 68′ regulated items, legal questions have emerged about a solvent traps’ intended use.
Legal issues over the use of solvent traps are not all about avoiding hefty fines. It’s about steering clear of felony charges as well. Some tips to prevent legal issues but also taking advantage of the cleaning opportunities that solvent traps offer to owners of firearms are as follows:

Do not Alter The Solvent Trap

A bullet will not move through a solvent trap. As a matter of fact, it would be dangerous for one to discharge a firearm with a solvent trap on it…think about a car driving full speed into a wall, get the picture? Some alterations to a solvent trap that look like they could be designed to allow a shot to escape might raise suspicion; even markings or indications on solvent traps may show “constructive intent” and may be deemed unregistered NFA items due simply to the fact that these markings exist! Ridiculous? Yes, that’s an understatement, but that’s where we find ourselves today.
Be cautious to prevent any adjustments or modifications to the tube, end cap, or threaded adapter or storage cups (dividers). Adjustments that look like they might allow or facilitate a modification that would then allow a bullet to pass through the firearm’s barrel while using a solvent trap wouldn’t be legal without the proper registration approval from the BATFE obtained through the Form 1 process.

When Using your Firearm, Keep your Solvent Trap at Home

It is still legal to bring your solvent trap with you when shooting at the range, but it is simply not necessary, unless you plan to clean your firearm at the range. This is not a requirement by law, but apparently regulators have grown overly-sensitive to anything that is shaped like a tube, even if their own spokesman deem solvent traps unregulated firearm accessories that fall outside of the NFA Handbook or Gun Control Act of 68′ escape apprehension altogether. If it’s not with you while using your firearm, a solvent trap can’t be used as a non-legitimate item.

If it’s not with you while using your firearm, a solvent trap can’t be used as a non-legitimate item.
When purchasing something of this nature, you should use legitimate channels and buy from companies such as Armory Den. Solvent trap cleaning systems like the Stainless Steel 1.10″ Adaptive Solvent Trap Kit (AST) and the GR5 Titanium Tube Solvent Trap Kit are sturdy and reliable, and most importantly they get the job done!

The Very Popular GR5 Titanium Tube Solvent Trap Kit

The GR5 Titanium Tube Solvent Trap Kit comes with 9 Stainless Steel Storage Cups. It has an overall perfect weight balance. Its extreme durability under all conditions is one of its unique selling points. The GR5 Titanium Solvent Trap Kit is 1.45″ OD (Outer Diameter) with a 7″ length.
All 9 cups that come with this kit are pressed stainless-steel cups, not giving space for flaws. A long-lasting solution that will aid your firearm routine cleaning and maintenance sessions.

The Titanium Solvent Trap Kit has a 1.45″ Outer Diameter and a 7″ length. When the weight and fit are dropped into the tube after fixing the titanium end caps, it oozes flawlessness. This explains why this kit was designed with a spacer and pressed stainless-steel. The thread pitch on the solvent trap is M34x1.25; before now, buyers’ possibilities of getting direct threading their solvent traps were limited. The M34X1.25 is rare and is not standard across the industry. A durable firearm cleaning kit, saving you from spending money on a new one soon.
Suppose you don’t want titanium and still desire quality tubes and end caps. In that case, there’s another offer for the same product in a 7075 Aircraft Grade Aluminum (hard-coat anodized in black).

The Stainless Steel 1.10″ Adaptive Solvent Trap Kit

This Stainless Steel 1.10″ Adaptive Solvent Trap Kit (AST) includes both a 1/2 x 28″ and 5/8 x 24″ Threaded End Cap Adapter for direct threading providing service to various barrels allowing and you to clean a variety of firearms. This firearm cleaning solution Kit (AST) carries the same modular cup design as our other Adaptive Solvent Trap models.
However, it’s a solvent trap kit made of 304 Stainless Steel with a highly sturdy matte black finish.
1/2x28 Solvent Trap
This cleaning accessory is a more durable option, even though stainless steel is heavier compared to Aluminum. The increase in weight makes it an ideal offer for firearm owners who want a solvent trap with a smaller diameter. Your firearm cleaning routine is made easy! The kit has a 6.4″ length in the most extended configuration and a 3″ length in its shortest design.
This Stainless-Steel AST weighs 14 ounces in its maximum size. A solvent trap specifically made for firearm owners who want a direct thread solvent trap without using an adapter from aftermarket parts. This is because of its narrow configuration.
