The ProMag MOS01 delivers what most folks need from a spare mag: solid construction, no-frills functionality, and a price point that won't make you hesitate to grab extras for the range. Built from heat-treated steel that's been TIG welded for strength, this 10-rounder uses a music wire spring and injection-molded polymer follower that keep rounds feeding without fuss when things are running smoothly.
One feature that shows up consistently in real-world use: the ProMag doesn't have witness holes drilled into the side like the factory magazines do. That means no debris getting trapped in those holes when you're shooting in dusty or outdoor conditions. The removable base plate also makes field cleaning dead simple compared to Mossberg's all-welded design. Spring tension on this magazine sits a bit tighter than factory specs, which some find requires a break-in period before everything cycles as smooth as you'd expect.
The magazine is manufactured domestically and comes with a lifetime warranty against defects. If something fails, you can send it back to ProMag for replacement. That said, the MOS01 uses precision tolerances that don't always account for variation in production, so some units may require a light hand filing on the contact surfaces if fit feels too snug in your mag well. It's the kind of thing you'll know in your first magazine change at the range.
The 10-round capacity keeps things practical for range days and training without eating up your shooting budget. If you're building a rotation of mags for your Plinkster, these work as solid standbys.
The MOS01 is designed specifically for the 702 Plinkster and most users report it fits and functions without issues. Some owners have mentioned the magazine feels slightly snug on initial insertion, which typically resolves after a few uses as the finish breaks in. If you experience a very tight fit, light sanding of the contact surfaces with fine-grit sandpaper can help.
The MOS01 solves one common complaint about factory magazines: it has no holes drilled in the sides that trap debris. The removable base plate also makes cleaning easier. The spring is wound tighter, which some prefer and others find requires a short break-in. The ProMag costs less than factory alternatives, and the lifetime warranty backs your purchase.
Most users report the magazine functions smoothly right away, but a light coat of gun oil or CLP on the follower edges can help if you notice any stiffness. The tighter spring means the first few magazine changes might feel more resistant than factory mags, but this breaks in quickly with normal use.
The package contains one 10-round steel magazine. It ships ready to use with no additional parts or tools required. The removable base plate allows you to disassemble the magazine for cleaning if needed.
