Responding to the US Army’s request for a new sub-compact weapon system, Charlotte NC based Angstadt Arms set out to create their shortest and most compact weapon ever, the SCW-9.

Having already designed the successful UDP-9, Angstadt Arms was no stranger to compact 9mm rifles. They drew upon this experience as they began looking to shrink their existing platform even further.

The Challenge

The SCW-9 is based on the same AR-style design as the UDP-9 with a closed bolt, blowback operated system. It is also fed by Glock magazines with last round bolt hold open. However, the original UDP-9 was simply too large, measuring 24″ long with a 6″ barrel and Magpul MOE stock.

The real challenge involved shortening the stock, which housed the recoil spring and buffer typical of AR-based rifles. To solve this, they created their own Sub Compact Weapon Stock which collapses to a mere 2.5″.

The new stock features a minimalist aluminum shoulder pad that collapses flush with the modified buffer tube. As a result, the SCW-9 measures only 14.7″ long and weighs 4 pounds, while maintaining a reasonable barrel length of 4″ and tri-lug adapter.

The stock system is also compatible with 5.56mm and .300 Blackout and will be available for purchase separately. In addition, it will be compatible with exiting AR-style rifles from other manufacturers. Work is also underway to design a pistol brace version of the stock system.

The Result

The Angstadt Arms SCW-9 does a nice job of retaining functionality in a weapon that will be instantly familiar to anyone who has handled an AR-style rifle.

It’s hard to comprehend just how compact the SCW-9 is without actually seeing it. Although I had seen numerous photos prior to SHOT Show, I was still surprised when I saw the final product with my own eyes.
