I have amended some of the the answers based on Rostislavs response. Some things have changed between the prototype and the production model. He does speak fluent English so he has his answers translated. I will mark which answers are from him.
Q: Any photos or videos of the side charging handle?
A: Rostislav- "The production model of the firearm will not have a side charging handle. The reason is a redesign of the bolt assembly—the firearm testing video already shows the modified bolt. The bolt has a dual locking system and does not have a side charging handle."
Q: What colours would it be available in?
A: "Any customer can have a car painted any color that he wants so long as it is black,"- Henry Ford
Truth be told, Rostislav wanted to make the gun stand out at IWA in a sea of black guns so he chose the robin egg blue. It also allows the features and controls to contrast well. First production will be black. The finish is cerakote.
Q: Will it lock into battery or slip out easily like the Taipan?
A: Rostislav- “There is no pump-action handle lock in the front section, but the bolt has a dual locking system."
Q: Can we get some mlok on the pump?
A: The pump itself is slimmer and would need to either allow space inside for the t-nuts or be hollowed out with a thicker design. Perhaps this is something the aftermarket can look at.
Rostislav- "The fore-end is too narrow for M-LOK. This can be replaced by mounting an angled 45° Picatinny rail onto the top rail behind the front sight.”
Rostislav- " We assume that the pump-action handle may be replaceable according to the customer’s wishes as a “custom” option, but it will not slip—this has been verified through firing tests. During rearward movement, grip is provided by the textured surface of the pump-action handle. During forward movement, both the pump-action handle and the bolt are under pressure from their respective return springs."
Q: Can we get a folding stock?
A: Theoretically yes, but practically no. We did not want to over complicate the design and inflate cost. The entire action is contained in the upper receiver and the stock tube is just there to host a stock.
Q: Expected price range?
A: Too hard to say at the moment.
Q: Any chance of proprietary mags so we can get more than 10 rounds?
A: Not with this iteration. The vision for this is to be an alternative for those who had a PCC caught in a ban. Most folks that I have shot 3-gun with had something that used Glock mags let that be a PC Carbine, FX-9, B&T etc. We wanted a gun that customers could use magazines they already owned, would be easy to source and of course are reliable.
Q: Would you ever consider a 7.62x25 version?
A: No. 9mm is the most available market standard. I have thought of this before with another PCC project. The issue becomes existing magazines. My thought was the NP762 mags but there is no longer a good supply of them or an easy method of getting them to a manufacturer to design the gun around.
