Frankford Arsenal Platinum Series Rotary Tumbler Spare Drum 7L

Description

This is the genuine factory spare drum for the Frankford Arsenal Platinum Series Rotary Tumbler, and it is a smart pickup if you clean a lot of brass. Instead of unloading, separating, and reloading the same drum every time, you keep a second one filled and ready to go. Load the clean batch out of one, drop the next batch into the spare, and get right back to tumbling. For anyone running big volumes of range pickup or match brass, that kind of workflow saves real time at the bench.

Why a Spare Drum Earns Its Keep

The big draw here is the 7-liter capacity. This drum holds up to 1,000 pieces of .223 brass in a single run, and a similar count of pistol brass like 9mm. If you shoot in volume or prefer to batch your cleaning into fewer, larger sessions, having two drums means you are never waiting on one to finish before the next pile goes in. It fits the full-size Platinum Series Rotary Tumbler exactly as the original did, so there is no fiddling or guesswork.

Built to Run Quiet and Protect Your Brass

The drum uses a dual-layer design with a molded-in rubber lining. That lining does two jobs at once: it cushions the brass as it tumbles with stainless pins and water, and it knocks down the noise so the tumbler is not rattling your whole shop. Wet tumbling with pins already gets cases cleaner than new, inside and out, including primer pockets and flash holes, and this drum is built to deliver exactly that.

What You Get With the Platinum Series Spare Drum

This is the drum assembly only, not a complete tumbler. It comes with two clear end caps and the rubber seals needed for wet tumbling, so it is ready to run the moment it arrives. Worth noting: this drum is made for the current Platinum Series rotary tumbler and does not swap onto the older-style Frankford Arsenal or MidwayUSA tumblers. If you already own the Platinum Series base, this is the exact replacement or second drum you want.
