Yes It does, it's a solid chunk of metal that's for sure. I was taking a close look at it yesterday and was just looking at the way the setup works . When the Underlever is pulled down,towards the end of the stroke . It would simultaneously raise the block. Its machined pretty flat cause on the piston side is where the breach seal sits at. On the Forward side it has a milled out edge that acts as a stop when it is pushed back down. Someone mentioned it's kinda similar to an HW57 but I never seen that gun in person. Also there is no baffling on the end piece either, the barrel runs all the way to the end . I can't wait until I get slightly better weather here so I can take my time and see how well or not well, it shoots. But its amazingly comfortable to hold . I'll post a video real soon to show anyone that's intrested in this rifle. So far it looks promising or that "closet wonder shooter" we'll see soon. I'm actually gonna leave work early to just run some pellets down range to feel it out. Temps in the low 30s out here.
