The MEC E-Z Primer V is an automatic primer feed system designed for the MEC 600 Jr and 700 progressive reloading presses. If you've spent any time hand-feeding primers into your press station by station, you know it's tedious, repetitive work that slows down your reloading rhythm and takes focus away from what matters—consistency and safety. This accessory eliminates that bottleneck by automating primer feed, so you can keep your hands free to manage cases and focus on the reloading cycle itself.
For shooters running high-volume rifle or pistol loads on a MEC progressive press, the E-Z Primer V turns a friction point into fluid motion. You're not hunting for primers one at a time or managing tiny components by hand; the system feeds them automatically into the primer arm as you cycle the press. That means more rounds per session, less hand fatigue, and fewer dropped primers—especially valuable if you're loading large quantities for competition, hunting season prep, or regular range trips.
This is a straightforward efficiency upgrade for anyone who owns a MEC 600 Jr or 700 and wants to reclaim time and reduce the tedium of manual primer handling. It's not fancy, but it works: one less thing to think about, one more reason to spend your energy on powder charges, bullets, and quality control.

| Product Type | Automatic Primer Feed Accessory |
| Compatibility | MEC 600 Jr, MEC 700 progressive reloading presses |
The E-Z Primer V is compatible with the MEC 600 Jr and MEC 700 progressive presses.
The E-Z Primer V is designed for the 600 Jr and 700 models. For Mark V compatibility, check the specifications of your specific Mark V model or contact customer service.
Instead of hand-feeding one primer at a time into each station, the automatic feed system places primers into the primer arm as you cycle the press. This keeps your hands free to manage cases and focus on other critical reloading tasks, increasing overall speed and reducing fatigue on longer reloading sessions.
