Yes, the muzzle is recessed with a series of 4 steps or actually a crown within a crown. This is more cosmetic than anything else as my trade mark on big barrels like this is usually a "triple crown"...

Yes again, the barrel is larger than what the receiver is and as such, I left the recoil lug off and the shoulder of the barrel itself acts as the recoil lug with the minimal recoil generated by the cartridge....
