I bought the Mav 88 8-rd 20" barrel from PSA for $220 over the weekend. I already have switched out the Knoxx stock to it. Also, I completely disassembled it and "honed" some of the edges. It works somewhat smoother than the very gritty feel and sound it had str8 out of the box.
I shot it a couple times just to see if it worked. It performs very much like a shotgun should. Bang! Slide, repeat.
I have no pics, but it is just like all the rest you have seen just in this thread alone.
Thanks for the input.
