Magazines considered High Capacity are controlled by the ATF and/or local jurisdictions are not available for purchase/shipment in all areas.



The Hera Arms H1 Magazine fits naturally in your hand with its tapered leading edge while a textured surface provides positive control.  Centering support fins along the mag square it off when inserted into the magwell, preventing it from rattling in place. Flush with magazine body, the floorplate is quickly removed by pushing out the locking tab making disassembly a breeze.

Really 9+1 Mag


Good:Fits well, no wobble, and quality construction. Great for shooting from a rest/lead sled and walking thru the woods while hunting. Bad: though you can physically fit 10 rounds in the mag you cannot load the mag with all 10 rounds with the bolt closed so this really is a 9+1 mag as you have to load a full mag with the bolt open.

I ordered these for spare mag's on top of that German engineering excellent on these ! I used them in my 300 blackout to see how they would do ran 100%

9 rounder

Disappointed. As mention you can fit 10 rounds but it wont seat fully. 9 rounds and it locks in

10 Rounds Fix


I got 10 rounds in mine and fits right in with the bolt closed. Slide the bottom plate keeper in the lower front magazine out. Take the spring and follower out and remove the spring. Cut about 3/8" off the front lower down guide of the follower. Reassemble and now you have room to load to capacity and insert with the bolt closed. Took me all of 5 minutes start to finish.

Economical and quality

Bought these despite some middling reviews. Using in my Mossberg MVP, and no complaints. Good size for benchrest or prone. No issues seating the mags or feeding.
<br>Would have bought more but for the 5 mag limit, and now they're out of stock.
