Frankford Arsenal 110V 7L Review

Frankford Arsenal rotary tumbler is one of the best products in the market right now. The Platinum Series Rotary Tumbler delivers a new level of brass cleaning performance. Rotary tumbling with stainless steel media in a liquid bath gets brass much cleaner and works much faster than ultrasonic or vibratory tumbling methods.

Frankford Arsenal Rotary Tumbler Reviews & Guide 3This tumbler can effectively clean without the use of stainless steel media pins and can clean using a mixture of brass cleaning solution and water. This thing works fantastic. It cleans the outside, inside, and primer pockets very well. Like everything in life, getting better results usually requires that you put in a bit more effort.


This tumbler features a dual-layer drum with noise dampening rubber lining for minimal noise while running.


The new tumbler is larger than the Rebel 17. For my 9mm test, the Rebel 17 cleaned 227 cases and the FA 7L cleaned 734 cases. I am not sure if the FA 7L will handle 1,000 – 5.56 cases as advertised, but based on my testing with 9mm the FA 7L probably will.

Frankford Arsenal Rotary TumblerThe Rebel 17 recommends running about two lbs of brass (approximately 230 – 9mm cases) with five lbs of stainless steel media. I believe the Rebel 17 has a 17 lb capacity. The drum for the Rebel 17 weighs 6.5 lbs (without the cover). For my first test the Rebel 17 I ran 227 deprimed and dirty 9mm cases.

The total weight of the drum, with SS media, brass, water, detergent, etc. was 23 lbs (15.5 lbs net). For the FA 7L 9mm test, I ran 734 deprived cases with 5 lbs of SS media. The total weight of the drum, with SS media, brass, water, detergent, etc. was 25.5 lbs.


The FA 7L has a timer switch (the only way the tumbler can be operated) with a maximum of three hours. This may be an issue as sometimes I let brass run longer than three hours. However, the Rebel 17 runs at about 32 RPM while the FA 7L runs at about 63 RPM, so perhaps the FA 7L will clean better in three hours.

As the Rebel 17 runs at about 32 RPM it is “gentler” than the FA 7L. This may prove useful for nickel-plated brass – I have not tested this yet, but I have worn nickel plating off brass by running it too long with the SS media.

Delivery (not too good)

The FA 7L was shipped in its retail box without an outer box. There was a packet of some blue cleaning solution (a liquid) that was taped to one end of the tumbler.

This was impacted during shipping (as far as I can see that was a foregone conclusion as the packet had no protection and was right on the end of the tank) so the blue liquid leaked all over the box and tumbler.

FAQ About Frankford Platinum Series Rotary Tumbler

What makes this better than the rebel 17?
Because the acronym is FART, Frankford Arsenal Rotary Tumbler. Way more fun than the rebel.
Is there a minimum number of cases to tumble? I have 380 .45acp cases I’d like to clean, but wonder if the tumbler will shine that small an amount.
There is no minimum number of cases per say to clean, and the rotary tumbler is rated to clean up to 1000 cases of 223 brass. You will love this product, and it will shine up your 45acp nicely.
Is the five pounds of media enough or do you need to buy extra?
It is plenty of media. It works great. I have found the secret to really shiny brass is to use dish soap and blemishing to clean. After that rinse and shake the pins out.

My last step and I believe the most important is to add clean water back in and put it back on for 15-30 minutes. Every time I have done that it has been great. Without the last step, it’s hit or miss with the soap get completely rinsed off and not leaving water spots.

Will this actually polish the brass to a polished finish or just make it shiny clean?
The brass looks brand new clean.
Want to clean old brass dresser pulls that have a small amount of paint in the crevices- will this both polish brass and remove the paint for me?
This is designed to clean and polish. It uses small stainless steel pins to ‘scrub’ the brass and using a solution of LemiShine and dishwashing soap does a pretty impressive job of polishing as well.

I don’t think the pins would damage the brass, but I’m also uncertain how long you would need to leave in tumble mode before cleaning out all the paint chips.

Bottom line

Frankford Arsenal rotary tumbler has an impressive capacity and does an excellent job cleaning your brass. You can use vibratory tumblers with NuFinish and other brass polishes, ultrasonic cleaners, etc.

But nothing does as thorough of a job inside and out as this does. The occasional pin gets caught sideways in the neck of 30 cal rifle cases, but it’s very obvious when doing your case inspections and easier to remove than dry media from the flash hole.
