There were two things that convinced me to by the KPOS instead the Roni; First is that the clearance of the KPOS over the ejection port of the Glock was much wider and lower than that of the Roni. This means less or none of the stovepiping issues I found with the Airsoft Roni.
Second was the fact that the muzzle tube of the KPOS is much bigger and allows for more room for the muzzle blast of expand, unlike the much more enclosed space of the Airsoft Roni's muzzle tube, which resulted in flame damage to the muzzle of my Glock's slide.

I bought the unit for P32k at Armscor, and it came with the following items:
- Large, black polymer case with gray foam lining;
- Carbine conversion unit;
- Special rear back plate for use with the KPOS;
- Tool for rear plate removal;
- Manual;
- Under the arm sling;
