Try this with your Fx.
Why would anyone do that? Not a 'real world' incident. Or maybe airgunners with LC100s are so irresponsible that they routinely leave their rifles leaning against their trucks and then drive off...or lose them in long grass and use a 2.5ton 4x4 to 'find' them.
I wouldn't expect any rifle to withstand that and wouldn't choose one over another because it could.
