Bought Bad Ace scope mounts for both a m38 Swedish mauser and K31 Swiss rifle. Both Bad Ace mounts went on easily, good directions too, and scopes wiork very well with these Bad Ace mounts. Saved original sights and parts in case I sell the rifles. Saw a guy at the range yesterday and he looked at the scope on my M38 and said he wanted to mount a scope on his M96, so I gave him the Bad Ace info so he could order one. Bad Ace was helpful and answered questions I had in ordering the right mount too.

The best scope mounting solution I’ve seen for a K31. Low rings and a 4-12x40 Vortex scope clears nice and low as possible. I did add a leather cheek riser for proper eye alignment but there’s no way around the need for that as this stock was made for using iron sights. The addition of the adjustable brass deflector is nice, but I also have the earlier version of this mount without it, and it’s always ejected spent cases just fine.

I first purchased one of your scout mounts for my K31 but the scope I had just didn't have the eye relief that I needed to make it work, so I bought this one. One thing the scout has was elevation adjustment screw was this one does not, again the scope I have didn't have enough elevation adjustment so I did a little packing out to give me the adjustment that I needed. Used it today and boom happy days.

Mounted full size scope on the K31. Worked well. On this rifle though... I prefer the Scout Scope mount. Just my preference for this one. I have several of these mounts for surplus rifles and they all work well. Above average products. With above average customer service. If you are like me and have difficulty seeing with iron sights at an older age. You won't regret getting one.

Bought the bad ace mount for my k31 and turning it into my go to deer rifle, was super easy to install and not permanent so if I want to put rifle back to factory just drive pin out and put irons back on. Shot the rifle about 20 times and seems to be holding zero. Would definitely recommend if your wanting to put a scope on your k31 and not permanently bubba it. Awesome product guys God bless you.

Installation Video

The following are links to the scope/rings combination we used in this video and we would recommend. We purchased these accessories ourselves, and we only recommend products that we trust and have been tested extensively by us.

We also recommend the following scope/rings combination:

NOTE: Traditional Picatinny rings typically use a single recoil lug at the bottom. However, we’ve found that some newer rings use two recoil lugs, and those are not compatible with this Picatinny rail. The rear (“tail”) section has only one slot due to limited space.
