"Excellent fit, Works perfectly"

Overall Product Rating:


Snug fit, bottom pin went in snug, top pin I had to lightly tap in place with a small rubber faced hammer. Installed with a Radian end plate and SB Tactical SBA3 brace. End result was a perfect, solid fit with no play whatsoever!! The finish on the adapter matches the Zenith perfectly. Excellent part!!
