The bolt cycles in the receiver and the barrel mounts to the receiver and is secured with the round threaded barrel collar that also acts as a short handguard. What exactly is your concern? I would be surprised if the receivers are different? It does look like they may offer a shorter barrel collar based on some of the pictures. The only other difference seems to be at the rear where the stock attaches the pistol version won't accept the long stock, but I thought I saw an option for a brace with maybe a vertical section of pic rail at the rear?My concern is the tubular unit where the barrel mounts and the bolt cycles. If both versions use the same assembly, there is a potential problem.
Hopefully these are popular for the manufacturer and we see several caliber options and perhaps even a willingness to do custom runs for the Canadian market.
My preference would be 12.5 inch barrels to meet BC hunting regs, and a vertical pic rail at the back so people can choose their own adventure when it comes to stocks, a compact folder that meets min length would be nice.
