The Jack

The Jack Build

“The Jack” lower receiver seemed like a great place to start. Our team had ideas the minute we saw the custom receiver. Inspired by the infamous “Jack the Ripper” playing card symbol, The Jack lower receiver is a testament to the fusion of art and functionality. The decision we came to was to build a 13.3″ barrel pistol-length AR-15 chambered in .300 Blackout. Selecting the remaining parts after the receiver took almost 4 weeks and some sourcing. We added a few custom pieces from Unique ARs, another awesome company to work with. For a complete list of parts, check out “The Jack” parts post we did before we started the build.

With some ideas, we generated doing “The Jack” build, some great team concepts, and some ideas the Unique Ars team brought to the table, the “Overthrown” was equally as fun as the previous build. We opted to go with an 18″ barrel chambered in .223 Wylde.

Overthrow AR-15 Build

With the “Overthrow” build, we wanted a longer-range rifle than the previous .300 Blackout build. We also decided to Cerakote both the top and bottom receivers. We opted for a “sword” themed custom Unique ARs handguard, which they did the Cerakote on both the handguard and receiver set. While the Cerakote was being done, we sourced the balance of the Overthrow parts.

Sharps Bros "Showdown" receiver

The showdown was the hardest of the receivers to get our hands on; it took months. Further, we were having trouble getting some background on it. We contacted Sharps Bros., and in a day of dying customer support, we were pleasantly surprised to get a reply from the founder John Sharps in less than a couple of hours. It seems their level of customer support matches the quality and attention to detail of their products.

John Sharps’s reply to our inquiry about the background of the “Showdown” was;

Showdown was mainly inspired by the desire to step it up and create something amazing for our final face design – and the Showdown warrior seemed like a great project. It took 10 years to design and release the 5 designs: Hellbreaker, Warthog, The Jack, Overthrow and Showdown.  Showdown completes the collection.  It’s by far the most difficult, over two hours of machine time per unit.
