Yeah, I did buy it. You have to slide it all the way to the lever side to open the lever to mount and dismount it. That is the only way that the lever will clear the slide itself. It is heavy and big. I like to use it w/o tightening it down for field work, it is fast and malleable this way. If you only use a bipod occasionally and are looking at clones anyway, this is the king of the clones for stability. It seems to be sturdy; but I am not going to test that out. Extended out, your top heavy bullpup is unlikely to fall over using this thing. In use, I can't believe they sell this for almost the same price as the small ones and I thought it would be cheap as hell, it isn't. I also bought the slightly smaller (and more expensive) carbon fiber Spina too. That one is still too big to keep on the gun all of the time, and not as dynamic in use. I am using this on what most on this site would say are cheap pcp's from China, so I think that they are suitable for me. If you have an airgun/scope/sideshot rig that goes for$5000+, then don't stop here, -get the real deal and be done with it.
