AR-MPR: Mounting Nikon Monarch Scope and M-223 Mount

In this post, we’ll look at what’s involved in mounting the Nikon Monarch 6-24 x 50mm riflescope to our AR-15 using the Nikon M-223 scope mount.

Before we get on with the video, let’s take a look at the finished product:

What’s nice here about using the Midwest Industries quad rail handguard, is the “continuous top rail” that it creates which extends the picatinny rail feature on the A3-style upper that we used for the AR-MPR project. This means we can move the scope mount further forward as needed (a good thing when optimizing eye relief for a variety of shooting positions. Here, I’ve measured what will be best for benchrest style shooting.

Here’s the video showing the process:

I plan to sight in this rifle at the range starting at 25 yards, then moving to 100 yards for the initial sight in. Should be fun!

Thanks,
Gavin

    1. Yes, that’s correct, I created an annotation to correct that, but it looks like it doesn’t show in embedded mode.

      All torque values should in in inch-pounds! 🙂

  1. GAVIN,

    JUST TUNED INTO YOUR VIDEOS LAST NIGHT. GREAT JOB! THE QUALITY OF THE VIDEO AND THE INFO YOU PROVIDE IS SUPERB! KEEP UP THE GREAT WORK!

    QUESTION? I AM IN THE PROCESS OF BUILDING A SPACE FOR MY XL560 (BENCH, SHELVES, LIGHTS) ETC…
    I AM CONSIDERING A CUSTOM COUNTERTOP OF 1.5 INCH HIGH DENSITY PARTICLE BOARD OVERLAID WITH A NICE SHEET OF STAINLESS STEEL AS MY WORK BENCH-TOP OVER A GROUP OF LOWER CABINET BASES. I NOTICED HOWEVER, THAT YOUR STAND THAT YOUR PRESS IS MOUNTED TO SEEMS EXTREMELY STURDY. I CAN DETECT VERY LITTLE MOVEMENT ON THE UP AND DOWN STROKE OF THE HANDLE. COULD YOU PROVIDE A LITTLE BACKGROUND ON THIS STAND? HOW YOU CAME UP WITH IT? WHERE YOU GOT IT? HOW ITS FASTENED TO THE FLOOR? ETC.
