This is a really outstanding Perazzi Stock Lock built for a MX10 originally. It has all the bells and whistles that Pat McCarthy puts on his stock locks. It has a really beautiful piece of upgraded English Walnut with a 14 5/8 LOP with the new Kick-Eez pad installed. I just got it back from Pat where he went thru it and performed complete maintenance on the internal system. As you can see from the pictures, it is in perfect condition with no dings or cracks. It will fit any MX3 Special/MX8/MX10/MX11/MX15 or MX2000 drop out trigger receivers. It went right on my MX8 receiver with no issues. I bought this Stock Lock to try and shoot on my MX8 step rib top single. It was just a little too high for me on that low Perazzi top single rib so therefore I'm selling it. Really liked it, but just won't work on a low MX8 top single rib for me. Selling for $1700 shipped to the Lower 48 states.
