I was recently contacted by a client who was considering purchasing a threaded ‘solvent trap’ adapter and using it as the basis for a Form 1 build of a suppressor.
For those unfamiliar with a ‘solvent trap’ adapter, it is an adapter that allows an oil filter to be threaded on one end and the other end will fit a threaded barrel.
As sold the purpose is to facilitate barrel cleaning but with a small degree of workmanship, a properly sized washer, and an oil filter they can be converted into a suppressor.
That is what my client was interested in doing. He wanted to file a Form 1 and, upon approval, legally build an inexpensive suppressor. However, before doing so he had several questions:
1) Which component would comprises the actual ‘suppressor’ … the adapter or the tube?
2) If the tube is the actual suppressor (or an integral part) then would he be able to change the oil filter as it began to wear?
3) Which component would need to be serialized?

Such buy a mini model between 1961 and 1963 but did not find any serial number or vin could help me and I do not have the documents I want to restore, I could help my email email protected From: Ameer. Date: @ 6:18 PM. I’m a bit of a torch nut. Used to have maglite in the 1980-90s and loved it. Esp the candle function. Then realised it was very dim around the time that LEDs started infiltrating 🙂.
The ATF has addressed these questions before and a copy of the relevant portion of a guidance letter can be viewed below. But the simple answers are:
1) The adapter and the oil filter together make up the suppressor as an integrated whole
2) While a licensed manufacturer could change out such a component, an individual or trust who made a suppressor on a Form 1 could not unless they registered a new suppressor on a new Form 1 and submitted an addition $200 tax.
3) The adapter and the tube would share the same serial number.
Therefore, it would generally not be cost effective to plan on using a ‘solvent trap’ adapter as the basis of a Form 1 build since you would be stuck using a single oil filter for its entire service life.
However, if you really like the idea of using an oil filter as a suppressor then there is another alternative.
Cadiz Gun Works of Ohio, which is a licensed manufacturer, sells a completed version of this design known as the EconoCan. And because they are a licensed manufacturer they can replace the oil filters as they become worn for a modest fee … $25 at the present time.
The relevant portion of the ATF guidance letter is as follows:
Most of us probably have a Maglite of some sort sitting around the house. Known for their superior build quality and durability, Maglite is considered to be the everyday premium flashlight. We will be taking a look at Maglite’s LED line of flashlights featuring the latest Luxeon Rebel LED.
Form Factors
The LED Maglite is available in several form factors and with two kinds of LEDs, and the type of LED is something that should be given some thought as there is a significant difference.
LED
Older lights are frequently still seen on the shelf, so the kind of LED should be noted. The current LED Maglites use the Cree XP-E LED, and previous generation LED Maglites use the Philips Lumileds Luxeon Rebel or Luxeon III LED. The Cree XP-E is brighter and more energy efficient than both Luxeon LEDs, however, older models are often mixed with new stock on retail shelves.
The Luxeon III (left) is larger than the Luxeon Rebel (right). The Cree XP-E is mounted similar to the Luxeon Rebel, and the main difference is the square base of the XP-E. The only way to differentiate between the models is to look down the business end of the light through the clear plastic packaging.
With the D-cell lights, the serial number also indicates the type of LED inside. If the serial number begins with DLXXXXXXXXX, it is either Cree XP-E or Luxeon Rebel. If the serial number begins with DXXXXXXXXXX, it is the Luxeon III. Also, if the packaging mentions interchangeability with incandescent bulbs, then it is the Luxeon III.
Sizes
Here’s the breakdown of the sizes that are available based on LED type:
| Luxeon III | Luxeon Rebel | Cree XP-E |
| 2 AA | 2 AA | 2 AA |
| 3 AA | ||
| 2 D | 2 D | 2 D |
| 3 D | 3 D | 3 D |
| 4 D |
The 2AA light is an exception and is actually available in three different form factors. There are two types of the 2AA with the Luxeon Rebel – one with the flat tail cap (old), and one with the lanyard tail cap (current), similar to the regular 2AA Mini Maglite. The lanyard tail cap is preferable to the flat tail cap due to increased reliability, as well as compatibility with regular Mini Maglite tail caps (making aftermarket accessories such as “clickie” switches usable).
A common question is 2D or 3D? The gist of that decision is personal preference. The 3D is a hefty light, but it has, by far, the longest runtime. The 2D is more compact, but runtime is shorter due to the need for voltage boost. The difference in brightness between the two is not very significant, so considerations should fall on runtime and size.
Pricing & Ordering
Compared to other premium flashlights, Maglites have one major advantage – local availability. At the time of writing, regular price for the 2AA is usually around $20.
Frys and Lowe’s also sell the lights online, but after reading the previous section, you will know that ordering online is not a good idea. I was able to pick up several 2AA lights for about $10 each, at Lowe’s and Home Depot during the year-end holiday sale.
The 2D and 3D models are a little more expensive, at around $30 for either. If you are a Costco member or know someone who is, Costco has a 2AA and 3D twin-pack that is a great deal for $29.99. Again, prices vary by time and location, so this should only be interpreted as an estimate.
In The Box
For the 2AA, included in the blister packaging are: Maglite LED 2AA flashlight, 2 x AA battery, and belt holster.
For the D-cell models, only the light is included.
Batteries
While the 2AA includes two alkaline batteries and the instructions specify that only alkaline batteries should be used, it is not recommended to use alkaline batteries. The reasoning behind this is that no matter the brand, alkaline batteries can and will leak! If the light is stored in extreme conditions, such as in the glove box of a car, the chances of leakage are much higher. Instead, lithium primaries or low self-discharge (LSD) NiMH rechargeable batteries are better alternatives.
Lithium primary batteries, such as Energizer Advanced or Ultimate Lithium, are more expensive, but last longer than alkaline, perform better in cold temperatures, do not leak, and are approximately 1/3 lighter than the average alkaline. The voltages of these batteries are also slightly higher, which leads to increased output compared to alkaline.
LSD NiMH rechargeables, such as the Sanyo Eneloop that popularized low self-discharge, are able to retain charge up to one year. One thing to note about LSD rechargeables is that Duracell Pre-Charged rechargeable batteries that have a white top on the positive end are re-packaged Eneloops, and these are preferred over the black top counterparts. If you’ve ever used rechargeable batteries, you’re probably aware of the extremely high self-discharge rate that could leave the battery half-empty in a short amount of time. LSD rechargeables are an investment that will definitely pay itself off if the light is used frequently.
For D-cell lights, options are more limited, and quality alkaline batteries are a good choice. Rechargeable LSD NiMH D-cells are quiet expensive and difficult to find, though AA to D adapters can be purchased online so that primary or LSD AA’s may be used. Some adapters offer the ability to hold 2 AA’s in parallel, which will greatly increase runtime. In addition, 2 AA’s will be lighter than a D-cell.
The Light
Head
The head features a plastic lens and a smooth reflector. The beam can be focused with a quick turn of the head, and the D-cell models feature continuous cam action so which direction the head is turned will not matter.
For the 2AA model, brightness will decrease beyond a half-turn due to increased distance between the LED and the reflector, but the head can be unscrewed all the way and the light converted into “candle mode”
Body
The entire light is type-II anodized aluminum inside and out. The anodizing helps prevent corrosion, and also electrically insulates the light. (Picture below shows lights with optional anti-roll ring accessory.)
The 2AA light sports a multi-mode switch with four modes: 100%, 25%, blink, and SOS. If the light is needed for an extended period of time, one set of batteries will last for more than a day on 25% mode.
The D-cell lights feature a three position on/off switch: momentary, on, and off.
Tail Cap
D-cell lights with the Luxeon III will have a spare incandescent bulb in the tail cap. For the Luxeon Rebel models, the tail cap is not very interesting and consists of only a spring.
Performance
If you’re an incandescent Maglite user, you will certainly be surprised with the output of the LED Maglite. LEDs give off a cool white color, do not generate as much heat, and are brighter. As with incandescent Maglites, the larger models can be used as a baton if needed, although using the head as the striking surface would not be best as the LED cannot be replaced like a bulb! Below are some beamshots of the lights in spot focus:

Check Maglite Serial Number
All of the LED Maglites are regulated, which means that as the batteries are depleted and voltage drops, more current is drawn from the batteries to offset the lower voltage, resulting in consistent brightness until the batteries are completely depleted.

Accessories and Upgrades
Maglite Serial Number Lookup
Maglite offers a decent variety of OEM accessories for their lights, ranging from belt holders to lamps to traffic wands. I purchased a D-cell and an AA accessory pack, which came with a rubber anti-roll ring that also protects the head and lens from scratches when set down head-first, as well as a set of red, blue, and clear lenses. The D-cell accessory pack also came with a pair of mounting brackets, which I found to be convenient for storing the light. The mounting brackets are quite firm and the light snaps in with a solid THUNK.
For those with incandescent Maglites, Maglite offers a 3W drop-in LED upgrade for the 2-cell, 3-cell, and 4-cell C or D lights, which uses the Luxeon III LED. This upgrade is being discontinued due to the older LED used, but there are aftermarket upgrades (including some with the Luxeon Rebel LED) available from manufacturers such as TerraLUX. For Mini Maglites, there are no OEM upgrades, but TerraLUX and Nite-Ize make 1W LED upgrades that will certainly improve the light’s usefulness.
Conclusion

These lights are certainly quite handy to have around! The size of the 2AA makes a great every-day carry (EDC) light, or could be handy to keep in glove boxes or emergency kits (with lithium batteries installed, of course). Whether you’re an avid outdoorsman or just wandering around the house late at night trying to find your bedroom, these lights are great value and will come in handy, ready for action, for years to come.
