F5 Manufacturing Is Making 50 Rd Drum Magazines for Pistol Caliber Guns. Check out the CZ Scorpion drum magazine.

F5 Manufacturing

There are only a handful of reliable drum magazines on the market. Beta has been making its dual drum magazine design for decades but they are large and heavy. 50 round drum magazines seem to be a good balance. However, your options are limited. Rifle caliber drum magazines like the Magpul D60 or the XS Products drums have proven themselves to work well. But what about pistol caliber guns like the MP5, Scorpion or the MPX? Well, step in F5 Manufacturing. They make drum magazines to feed your favorite 9mm bullet hose. Check out this CZ Scorpion drum magazine!

The CZ Scorpion drum magazine manufactured by F5 Manufacturing is compatible with pistol and carbine models chambered in 9mm.

F5 Manufacturing Drum Magazine Development

They started with the MP5 drum magazine, which took a year to develop. Later, they branched out to make the CZ Scorpion drum magazine. F5 Manufacturing makes its drum magazines with 6061 aluminum. They hold 50 rounds of 9mm.

F5 Manufacturing MP5 drum magazine.

Compatible with HK MP5 models and variants. Designed around the Zenith/MKE Z5-series models, as well as Dakota Tactical and the Quarter Circle 5, chambered in 9mm.

They are coated with Cerakote. The MP5 drum took them a year to develop. This is due to the variances in different roller lock manufacturers.

  F5MFG MP5 50 round drum mag has been in development and testing for over a year. We’ve found that mag well dimensions vary from different manufactures just enough to make a precision machined part fit loose in one manufacturer and tight in another (HK for example). Given this scenario, we’ve overcome this obstacle to make for reliable feed/function thru an adjustable shim system.

A tighter fit vs loose (loose being 1/8″ max front to back play) is required for reliable feed.

Insert magazine in mag well and observe fitment, the aluminum shim is malleable and witness marks will be visible (normal). This can be considered part of the wear in/break in procedure.  If too tight, the shim can be adjusted by peeling back one of 6 layers that are .003 thick to achieve desired fitment.

 

So they claim compatibility with the top roller locks on the market.

CZ Scorpion Drum Magazine

They had an easier time designing the CZ Scorpion drum magazine since the gun is built with more consistency.

In the top photo they announced that they are making a drum for the B&T APC 9. The only gun left on the list of trending 9mm pistol caliber carbines is the Sig MPX. Don’t worry, they are on it.

Manufacturing Drum Magazines

Making drum magazines should not be very difficult. If the drum is reliable it should not be too difficult to redesign the towers to fit different guns. Since the F5MFG drum is metal it is a bit heavy, but their design is compact. In fact, the drum mag height is shorter than a standard 30 round magazine. The MP5 and Scorpion drum mags retail for around $200 so I suspect the APC 9 and MPX drum mags will be similarly priced.

    I need 50 rounds of 9mm desperately. .

      50 rds would be nice for my new Spike’s Tactical, built to use Glock mags. Unwieldy, I’m sure in a 19,26; or 34; but might be workable in emergency. I sold my Rock River complete lower that uses Colt mags in order to have them operate with Glock pistols, too,

    No Colt-style AR-9mm drums?

    Someone has come up with a mod for the Hi-Point 45 carbine that allows it to use standard 1911 mags, including a 28 rd drum ……….how about F5MFG following suit for the Hi-Point 9mm carbine….??

    • Brandon Badger

      Did you just admit to owning a Hi Point?

      • Dave

        Yes, with the conversion……and a drum…..parallel firepower as a Thompson at a significant cost savings….
