So the hammer hits that extension on the bolt carrier, which triggers a firing pin? The charging handle seems to be non-reciprocating, so is there any form of forward assist?
The major win with that kind of bolt carrier design is that it can be very compact, removing the necessity for having a lot of room for recoil movement inside the stock. Thus the magazine well can be closer to the buttplate. One could even have a collapsible stoc for minor adjustments. The downside would be the inevitable complexity of the component.
I designed it this way so that the cartridge could be dropped out behind the magazine, thus eliminating the issues with ambidextrous bullpups of the past. It also lowers the rate of fire, and hence perceived recoil.
There is a forward assist lever, it's collapsed along the top of the weapon, ontop of the bolt carrier. You flip it up if you need it.
