The 3D printing wars are hotting up, as Thingiverse users upload a design for an AR-15 magazine (holds five rounds, easy to expand to as many rounds as the material will hold without snapping) and an AR-15 lower receiver, a component whose ownership is proscribed or regulated in most of the USA.
This is a near fully printable 5.56mm X 45mm or .233 REM AR-15 magazine. It is current only a 5 round magazine. I left my printed spring design out on purpose for saftey reasons. However, with a little printing experimention and some range time it can be made easily.
The Lower Receiver is the frame that holds together all the other pieces of the firearm. In the States, all the other pieces can be purchased without a permit - over the counter or through the post. The Lower Receiver is the only part which requires a background check or any other kind of paperwork before purchase.
Typically this part is made of aluminium. A rifle with a Lower Receiver made of plastic can be perfectly functional.

California criminal defense attorney Rick Horowitz had a juvenile client, he was shocked when the prosecutor in the case told him that to see the evidence against his client, he’d have to log in to evidence.com, run by Taser International (now rebranded as Axon).
Bamboo has lots of uses beyond just being panda food. Things like bikes, roads, scaffolding, and musical instruments are made from the fast-growing grass. But unless you are participating in a tropical-themed LARP, you probably wouldn’t want a shirt made from bamboo stalks. So why do bamboo bed sheets make any sense? Because yarn extracted from […]
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
