Had the chance to check out one of these MP-513M air rifles recently.
http://www.baikalinc.ru/en/company/117.htmlWhat makes it unusual, is that it is a spring piston airgun that has an exposed spur hammer that has to be cocked in order to fire the gun (like an exposed hammer shotgun). The hammer acts upon the sear, knocking it out of engagement with the piston. The premise is that a much lighter trigger pull is attainable. I wasn't able to actually shoot it (it was at a store), so I can't comment on it's actual feel, firing bahavior, or how the hammer drop sear arrangement affects the lock-time, etc. I can't really recall seeing this type of an arrangement on a springer in the past, so this may be a new innovation in the airgun world. Is there anyone else other than me that this is "news" to? Anyone own one of these rifles that would care to comment on firing behavior?
Also, forgot to mention in my initial posting - much of the metalwork is aluminum alloy. For the sheer size of this magnum class rifle, it is super light in weight. I have some apprehension as to how well that aluminum alloy main tube will stand up to the rigors of a magnum class springer, and as well, how well the steel lined alloy barrel will withstand cocking a very powerful mainspring. I guess time will tell. The finish looks similar to parkerized steel.
