ditto on the skinner.....
After trying the x/s sights, I realized that you can't use them to any precision, at least not for me, beyond 50yds
. I tried the williams 5d sight, which was great, for quick shooting, and precision shooting....(I.e over 150yds)... and very flexible with aperatures available for anything front twilight shooting to rapid snap shooting to real small hole aperatures for precision shooting...you dont even have to change out you stock front sight. It was also the easiest sight to adjust. In the end I wanted something a little slicker, that was adjustable, made from steel, and had aperature for precision shooting. The Skinner sights are perfect for that, even though he includes an aperature with his sight, you can use williams screw out apertures too!!
He only make sights for Marlin rifles, and I'm going out on a limb here.....but hands down.... the Skinner is the BEST receiver sight made for the marlin
.
Just do a search at MARLIN OWNERS.COM they think so too.
BTW you will need to change your front sight for the SKINNER, I used a williams FIRE SIGHT front in .375 height....this give plenty of adjustability
up and down for use with a broad range of grain wieght rounds. I also like the hood on the front sight for it's protection.....so I called Marlin and they sell a stock cutout hood for the 1894c, which lets the light in for the FIRE SIGHT, and protects it from damage.
