I can't say it is the best.
However I can say it has been a quest to get a RMR on this Merkel 141 double for a least a couple years, and I like it.
This particular Merkel is chambered for the 8 x 57 JRS cartridge and has a single trigger. The right barrel fires first, always, and the recoil cocks the trigger to fire the left barrel.
Shots 1-7 were to get within minute-of hoglet at 50 yds. Shot #8 was the left barrel.
It works.
First blood for the Trijicon RMR @ +/- 65 paces.....
Small javelina sow that was a target of opportunity!
ya!
