The HALO PDW from SIG SAUER utilizes a short stroke pushrod and will be offered in multiple configurations including barrel lengths, multiple calibers and even comes in an integrally suppressed model.
Shooters can easily switch between 5.56, 7.62×39 and .300 AAC. The upper is said to be compatible with any Mil-Spec AR style lower and as you can see in these photos, due to the operating system, it will accept side folding and collapsible stocks.
You may notice the 3D modeled brass deflector. This is so that they can rapidly test multiple versions in order to determine the most effective size, shape an angle for use with this weapon.
