In September 2018, the U.S. Army awarded Angstadt Arms a contract to supply ultra concealable 9mm sub-machine guns for the purpose of protecting high risk personnel (HRP). To address this operational need, personnel security detail required a weapon with greater lethality than pistols but more concealability than rifles.

The ultimate objective being a highly concealable Sub Compact Weapon (SCW) system capable of “engaging threat personnel with a high volume of lethal force while accurately firing at close range with minimal collateral damage.”

The SCW Stock system is what allowed our SCW-9 sub-machine gun to achieve an overall length of just 14.7″ without sacrificing barrel length or a standard muzzle device.

Key Design Features

Truly Sub Compact

The collapsed length of the sub compact weapon stock is just 2.5″. Allowing your rifle to travel inside smaller, more discreet bags.

Multi-Caliber Compatible

5.56 NATO, .300 Blackout and 9mm configurations available.

Upper Receiver Single Rail System

Unlike other PDW stocks the single rail on the SCW stock is positioned alongside the upper receiver. This provides added clearance above the safety selector switch resulting in faster manipulation and safer use.

Faster Deployment

The stock can be opened without pressing a button. Just grab the stock and pull back.
