So heres a little review on the 0561 i picked up a few days ago.This knife is a home run.It has been with me since i got it and i dont see it going anywere for quite some time.
It actually makes my XM18 3.5 look small but there is no real noticeable weight difference, which i think is a Big plus.
I had a chance to pick between a few of these a the place i purchased and chose this one because of the Detent.It is VERY Strong.All of them had a strong detent ,but this one was noticeably stronger than the rest.And it Fires hard and fast.
I was lucky enough to get a low serial number too (0037)..
The blade is perfectly centered with no Blade or lock play at all
And the KVT system is just plain awesome.Hers a short vid of how smooth it is(sorry about the crappy video)
I just cant say enough good things about it.Here are a couple more comparison pics
