There are several types of PCC or SMG operating systems that are popular. The HK roller-delay system, the Stribog roller-delay system, the CMMG radial delay system on the Banshee, the gas piston, and straight blowback operation. I show some of the more popular firearms and discuss the pros and cons to each operating system.
We take out a PKM using 174gr ball ammo and put it up against RMA NIJ level IV plate armor to see if it meets or exceeds NIJ standards. We take a look at the back face deformation too. Level 4 armor is rated for most common rifle calibers.

B&T has released the StationSix pistol which was previously known as the VP9. The StationSix is a modern take on a classic WWII covert operations pistol known as the Welrod. We do meter testing with 3 silencers and show a full disassembly. I forgot to mention the price: $2,249.
