Dnz black12042 and silver 12042s mounts excellent - DNZ Products Game Reaper Scope Mount - Marlin

Like the title says, Excellent.. fit, finish and quality. So here is my combination of use with each:

Black 12042 mount on the Marlin 1894c 357/38 special lever action carbine w/ the Nikon 3-9x40 1" Matte BDC Riflescope #16017.
The medium height mount worked out perfect for my eye alignment with the rear objective of the scope. The factor mounted rear sight blade had to be folded down to provide clearance, but other than that.. perfect. Build and design EXCELLENT! Color matches the Black Scope perfectly.

Silver 12042s mount on the Marlin 336ss 30-30 lever action carbine w/ the Nikon Prostaff P3 3-9x40 1" Silver Riflescope #16592
The medium height of this mount worked out as well, but in addition to folding down the rear sight blade, I also had to remove the elevation ramp to give enough clearance below the scope's front objective. Build and design EXCELLENT! Also, finish matches the silver color of the scope perfectly.

In conclusion, the medium height worked out for me to be perfect for my eye alignment but the high mounts would have given more clearance with the possibility of not aligning with my eye as well. So it becomes personal fit and preference between the medium and high mounts. Do your research by watching how to videos on riflescope mounting and eye / scope alignment as far as mount height, but either way the DNZ Game Reaper Scope Mounts are the best I've ever installed.
