3D Printing & DIY
Someone (@Prometheuzzzzzz) released files for the "Buffer Stuffer," a series of 3D printed components that can be inserted into an AR-15 buffer tube to convert it into a .22LR silencer.
The documentation suggests avoiding PLA/PLA+ filament (too heat-sensitive) and opting for PETG or better. Once the baffle stack is printed, you drill out a 0.28"+ hole through the whole column and install your 1/2" x 28 or desired thread adapter. The aluminum buffer tube acts as a rugged housing for the components.
On the off chance that anyone on this mailing list doesn't know what the buffer tube is, here's a diagram (shamelessly stolen from an Aero Precision stock image):
The smart thing here is that ordering a buffer tube from Brownell's doesn't raise eyebrows in the same way that ordering a Chinese "solvent trap" does. This approach is a clever way to allow folks to build a silencer without ordering parts that are obviously going to be repurposed and may draw the wrong type of attention.
There's probably an argument to be made that having buffer tubes in your safe instead of solvent traps will protect you from a constructive possession charge too, but I'm not a legal expert, so consider this info at your own risk.

Ivan's/DD's/Fuddbuster's Amigo Grande is now available to the public as a completed release. This project takes a .308WIN CETME C/PTR91/G3 parts kit and 3D printed clamshell-style receivers/handguards and turns your mid-20th century battle rifle into a modern crypto-anarchist bug zapper.
Now, this build is a bit more advanced than other DIY projects. Going all-in, you'll need to use a hydraulic press and feeler gauges to correctly set and pin the barrel into the trunnion and space the bolt. This is well beyond a Glock build in terms of a technical challenge.
The project does have excellent documentation (a 95-page PDF with color photos and step-by-step instructions) and supporting how-to videos. One should probably expect to see someone selling pre-fabbed bolt/trunnion assemblies before too long, too. If you have a Dremel tool, a halfway decent workshop, and the spirit of a warrior, then it will be an excellent project gun. Download it [Here] and follow Ivan [Here].
