The SMP-40 - 3D Printed MP40 Clone

An early October 7th anniversary miracle! Stubbs from Black Lotus Coalition has released his 3d-printed MP40 clone. It uses an AR15 fire control group, an AR barrel, what appears to be an AR9 or UZI magazine and an aluminium receiver-liner. One of the biggest 3d print projects of 2025 that has got me most excited! Introducing the Stubb Maschinenpistole 40 from developer Stubbs and the Testing/Developer team over at Black Lotus Coalition! This PDW is based off of the German WW2 MP-40 and is basically a DIY build using a tube you cut, AR9 parts, and a printed chassis. This build is as close to the original as we can get without stamping it and machining every part by hand. Thanks to everyone over on our side who put in the effort and for 3DPF for the awesome affordable parts kits! Hope you all enjoy this one!

Oddware: Hera Arms H6, side-fed mag bolt action

The Hera Arms H6, a side-fed-magazine, modern, bolt action chambered in 5.56mm. I am a sucker for anything with a sideways magazine and I was interested in this when I heard about it years ago. But there are already dozens of 5.56 bolt actions, including several different AR15-based bolt actions, a 3d printed mauser-style 5.56, and even a 3d-printed side-fed bolt-gun based on a Halo sniper rifle (link updated!which I cannot find anywhere, it might have been a photo on twitter part of a closed beta project).

I quickly lost interest in the Hera H6 knowing I could possibly build something like it - that and I already bought a cheap Savage Axis in .223 so the allure of owning another 5.56 bolt action has been lost for me, but it's nice to see unique and odd weapons still being released. From Hera-USA:

Earlier we announced the new H6 repeating rifle from HERA ARMS Germany Earlier we announced the new H6 repeating rifle from HERA ARMS Germany, but what’s the latest on Hera’s repeating rifle? We’ll give you an update on the revisions and show you all the features of the final version! Get you all the information you need today!

Due to the high volume of customer feedback, HERA Arms went back to the drawing board and incorporated some changes, including elementary ones, into the new H6. The first weapons will be delivered in the spring (which will certainly please the existing fan base).
