I dunno, that last gun pictured could get real painful, particularly with that cocking handle coming back where your teeth are if using the sight/scope. Anyhow I thought it funny given that left handed guns are pretty damn rare, and it gets even more funny when you realize that the selector switches are all also on the wrong side too (left handed ejecting guns with ambi selector switches are even more rare).
But I've seen that lots before. A lot of modders who make these models, don't know the first thing about guns
