80 Percent Arms Introduces GST-9 Ghost: First Truly Modular 80% Pistol Frame System

Tuesday, November 19th, 2019

Garden Grove, CA., (November 15, 2019) – 80 PERCENT ARMS, Inc., the nation’s largest manufacturer of 80% firearms, is proud of our history in challenging the status quo by releasing new products that have revolutionized the 80% lower industry. Today, we are continuing the tradition with the release of our new GST-9 Ghost: the world’s first truly modular 80% pistol frame system compatible with Glock® 19 platform components, as well as our patent-pending modular grips allow for easy conversion between compact and full size. We started by taking a close look at the famously reliable Glock® platform, diligently researched what was missing on the market today, then used our years of expertise manufacturing 80% firearms to develop the most shootable 80% pistol system from the ground up.

Based on extensive research and focus group testing, we also improved ergonomics by designing a contoured grip that improves comfort and helps tame recoil. The undercut trigger guard gives you a higher grip on the frame, thus lowering the bore-axis and reducing muzzle flip for faster, more accurate follow-up shots.

The GST-9 Ghost features several improvements over the time-tested Glock® platform, starting with the mating surface between the slide and frame. Frame rails have been extended three times their normal length for more repeatability, better accuracy, and controlled recoil impulse. Nickel plating improves reliability by reducing friction between moving parts in the harshest conditions, even after liquid lubricants have long since cooked off. 

The GST-9 is centered around one thing: you. There is no one-size-fits-all solution to your mission. That’s why we designed the GST-9 to allow every shooter to build a frame that is tailor-made for them. Whether it’s a compact or full-size grip, a streamlined magwell for carry or a flared magwell for competition, we give you options. Build the frame you want for your mission with the 80 Percent Arms GST-9 Ghost. 

Blast From The Past – The Arcus 3D-Printed Rubber Band Gatling Gun

Tuesday, September 17th, 2019

A few years back, I briefly mentioned The Arcus, A 3D-Printed Rubber Band Gatling Gun. Since the original video was taken down or otherwise made unavailable, I’d say it’s worth a revisit.

As the title states, The Arcus is a rubber band Gatling gun, made with 3D-printed components. It fits over the forearm and is capable of discharging 48 rubber bands in seconds. Impressively, the gun has no external firing mechanism, aside from the initial trigger pull, as it’s powered entirely by the energy from the rubber bands that it shoots.

What’s also impressive is the design: the Arcus requires no adhesive or fasteners to construct; all the parts snap together, and it can freely and repeatedly be taken apart and reassembled. The parts themselves are designed to be printed without any supports, and all fit on a 200mm x 200mm print bed.

So, if you have an appropriate 3D printer, or access to one, and are looking for a cool new project that involves the rapid discharge of projectiles, then you may want to give The Arcus a try.

The full instructions and part files can be found at the link below:

Make It Extreme – DIY Electric Rotary Gun

Tuesday, February 26th, 2019

YouTube channel Make It Extreme planned out and built a ‘DIY Electric Rotary Gun’. A more detailed description of the build can be read here, but essentially they developed a motor-powered gun that feeds round projectiles from a hopper into an aluminum spiral-walled ‘barrel’ (a piece repurposed from an air compressor). The makeshift ‘barrel’ rotates at approximately 3000rpm, in which the rounds launch around the walls of the barrel until shooting out the opening, with a surprising amount of force. As the video clearly demonstrates, this isn’t a particularly accurate gun, but this inaccuracy is offset by the massive volume of projectiles, 8mm plastic shots for the purpose of the video; although the creators state their gun is capable of shooting both plastic and metal shots sized from 6mm to 9mm.

The video shows the non-descript build process for the gun, but if you want to make one for yourself, you can join the $10 tier of their Patreon, and you’ll have access to the plans. Also, to be fair, a common interpretation of DIY is you can do it yourself with fairly common tools and implements; the equipment in this video, such as the lathe and press, are fairly specialized components, so how DIY this project truly is can be pretty subjective.

It’s still pretty darn cool, though.

How to make a Quadcopter Drone From Cardboard

Sunday, November 26th, 2017

YouTube Channel SKM shows off how to make a quadrotor drone from cardboard. Well, specifically ,a model of a quadrotor drone; this one doesn’t work as a drone as-si.

Still, a good DIY project is a good DIY project, after all.
