We are in the home stretch now. The design of the mag body, insert, and floorplate is finalized. The design of the follower is finished, too. We just need to mill some tooling for the follower. That will happen over the next two or three days—and we’ll be there.

Some of the features that put our all-metal magazine head and shoulders above the competition include:

• Mag stop. On the front of the mag is the mag stop—a go/no-go feature IMHO. The important feature prevents over-inserting a mag into your gun with the bolt in the open position—and bending your ejector rod, which can quickly ruin your day at the range.
• Robust, high-reliability feedlips. The feedlips are designed for optimal ammunition feeding. I wish I could take you through all the ins and outs of what makes these feedlips king of the hill, but that would take a doctoral dissertation to explore. One thing you should know is that these mags make your feedramp redundant. The rounds never even touch the feedramp. So if you have a feedramp that’s out of spec—almost the norm for these guns—resolve your feeding issues once and for all with these super high-quality magazines.
• Compatibility with the Uplula. Yes, you can easily load your Shockwave M11/NINE mags using the handy Butler Creek Uplula mag loader.
• Works with all stock designs. We designed this magazine to function with all stock designs—including the factory folding stock.
• Ammo witness holes. The oblong holes on the left side of the mag allow you to see remaining ammo at a glance. (There are 30 rounds loaded in the mag in the first three pics, and you can see that rounds 10, 20, and 30 are perfectly centered in the windows.)
• Optimally placed mag catch. The cutout for the mag catch is on the rear of the mag. (Note that the mag pictured is still a prototype. The welding on the production mags will be much much better. )
• Anti-tilt metal follower. In the final pic, you can see how the follower sits. (The follower shown is simply a 3D printed piece. The production followers will be stamped sheet steel.)
• Black Oxide finish. Rugged finish will protect your magazines for decades to come.
• Ease of disassembly. Magazine disassembles without tools for cleaning.

Almost ready for beta testing, which will begin the first week of October. Test units will be shipped to the beta testers before then.

Let me know your thoughts.

Thank you,
