Home Forums Birds & Dogs Shotguns Winchester SX3?

It's hitting about 8-10-12" left at 40yds.

I can see it when I mount the gun with my eyes closed, Open them, and the bead is about 1/3 from the left instead of centered on the rib.

Drop seems good, There's about a 55/45 split on vertical which works for me.

The O-ring in the gas chamber has a pretty good scarf in it. How critical is the seal on this one?

Shims are available to change the cast. Hope that solves the left shooting problem. I didn't need to install cast shims on my black shadow. Let us know how you make out.
