The scope mount installed exactly as advertised and is a very ingenious bit of no-drill engineering. Whomever designed it should be commended for finding a simple but very effective solution mounting a scope on a mil-surp rifle not intended to have one.
I mounted a Vortex Crossfire II scope but had to file down the front angle part of the mount because it was stopping the scope from seating properly. Knowing these rifles were intended to be used with iron sights, I expected I would have to shim/shave/adjust some items along the way. Being aluminum made it easier to file off enough material to get it where I needed.
I also rotated the scope 90 degrees so one of the adjustment knobs was clear of the ejection port. The K31 can really launch a spent casing and I learned very quickly that port needed to be a clear as possible.
Lastly, the beauty of this mount is the integrity of the original rifle remains intact and the rear iron sights can can be re-installed without issue or modifications.
Worked as advertised. Just removed the sight, attached the nut to the barrel, inserted the sight pin and locked down the screw. Took all of five mins.
Great mount, I had the pleasure of trying it out at the range yesterday. What impressed me was the stability, it was rock solid when I shot and the cartridges were expelled smoothly without any interference from the scope mount. Great addition to a phenomenal rifle.
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.
went on just like they said it would. Haven't shot it yet but foresee no problems.
The scope holder is a smart design and was easy to mount. I used a cheap 8x32 scope and it worked fine. Too bad the rifle kicks a lot harder than it did 15 years ago, 81 year old shoulder did not like it too much.
I bought one of Badace scope-mounts for my Lee enfield and my most recent purchase a Swiss K31. These mounts are excellent it’s nice to by a product that works flawlessly.
It was an easy, no drill installation on my K31. The mount is steady and solid. Once on, it was an easy job to get it sighted in. I used a fixed power 10X tactical scope, and was shooting 1 MOA groups at 100 yds within 30 minutes of starting the process.
Did not install it yet I still need to purchase a scope
Best way to mount a scope on a K31. No permanent modifications, and it’s rock solid. It helped me make my K31 my go-to deer rifle this past season.
mount was exact fit and my new scope for my k31 mounted with no adjustments could not be more pleased
I’m excited to try this mount on my new to me K31
Excellent quality!!! Very happy with the product!!!
the directions received (plus U tube) made the removal of the old sight and the install of the new one quick and simple...I am in the process of sighting it in at this time..would recommend this mount to any one wanting to to install a telescopic sight on a Swiss K31 rifle.
Works well and is good quality.
It's a very smart design and setup. Easy to mount and totally harmless to the value of my K31. I see the great potential of my rifle with it. Thank you so much!
Easy to mount to the gun. It is a soild mount. Just puts the scope a little high
Excellent product: very sturdy, well machined and hand finished like the original platform.
After we saw the instruction leaflet and video, installation was a no-brainer. Now the search for a vintage, period correct scope can truly get going!
I tried another "clamp on" mount and was not satisfied. This mounts at "two" strong points. Easy install. I aligned the rings with a lap bar, mounted the scope and was amazed I was able to zero this rifle in with six rounds. It's been consistently on target, which is what I was looking for.
The rail purchased was easy to install, the kit was fully comprehensive, to include locktite. The price was very reasonable, especially for a specific application.
Very easy installation. Shot 1.25" groups at 200 yards consistently which is quite good for my abilities. Seems very durable and well-made. Definitely recommend.
So I glad I got this rail for my Swiss. Easy to install and solid!! Thanks!!
The railmount is rock solid on my K31. I needed this because the front ironsight is off and I couldn't fix it, so I decided to mount a nice deer scope to it. Installation took less than 10 minutes following a youtube video, and the system is creatively uninvasive (non-permanent) to the gun. There is no slop or play in the mount, I feel like I'll never need to tighten it thanks to the included blue locktite. It's a great mount that I definitely recomend for anyone looking to explore the true potential the K31's range.
Excellent fit, easy installation.
the mount was very easy to install on my K31 and i'm not a gunsmith though I do mount my own scopes.After allowing the threadlock to set it's off to the range where it took only 3 shots to zero the scope fired 5 more to be sure I heartily recommend this mount to anyone with a K31 or any of the older rifles that Bad Ace has mounts for.Keep up the good work guys and Thank You J Johnson
Super easy to install and rock solid. Best K-31 scope mount out there. Period!
Most impressed about the engineering/machining: very nice tight fit of all parts,
Looks like ejecting shells will not be a problem, Several, from mid to long range scopes mounted w/o a problem, for the K31 mount be aware: the rearmost rail section has limited
slots, due to the fact that there must be clearance for the ejection of the sheels.
In addition, to have the mount be low, you will be restricted on how far back you can set the scope because of the ramp in the scope mount. of course you can choose higher rings, though then losing cheek weld.
Overall I am convinced this one is one of the best option for the K31 scope mounting!
I recieved the K-31 rail in good time...placed it on my rifle.
It was easy to place. I am very happy with this product.
The design and installation steps were perfect!
absolutely the easiest mount for the K31, fits like a glove, looks fantastic
I put a 4x12x40 Leupold on top. I recommend this for anyone withholder eyes and a K31!
Fast easy ordering, shipping was on time
all around great
Fit great arrived in a timely fashion

Went on within minutes. Could not have asked for a easier transition. Keeping this beauty tap free was the only way I would scope it. Even the old timers were impressed and that's not easy to do. Will prob order other mounts for my other MILSURP guns.
Product was high quality, easy to install, looks and functions GREAT! Highly recommend!
Excellent fit glad I did not have to bore into rifle. Works great. Ken in Tennessee
It takes longer to remove the parts from the bag than to install them. Machined expertly.Thanx for a great product.
Nice product, easy to install and very solid!
Installed on my K31 within minutes as advertised. The Nikon scope and rings installed with no issues.
Took it to the range to sight everything in. After minor scope elevation and windage adjustment got to enjoy tight groupings in the black at 200 yards at the range. Look forward to the next visit and having a go at steel target 300 yd range nice products. Especially like the design deflecting the spent cartridge to the side protecting the scope finish. Have to bring myself to do the same for my 1911??
The no-drill mount is very well made and finished. The video instructions are easy to follow and removing the old sight and replacing it with the scope base is straight forward. I used some spare Millet picatinny rings and one of my old Redfield Widefield scopes. Typical of these milsurp mounts is the higher than usual profile of the scope mount and also typical with milsurp rifles is the lack of a higher comb and cheek piece on the military stocks so I put on my old Cabelas leather cheek piece that I used to use on my No. 4 Mk II. If I ever get some free time I will get to the range and try it out. I might like to get a mount for my M44.
This Swiss K31 NDT (No Drill-Tap) Scope Mount Low Profile with Picatinny Rail Gen 3 is the dog's nuts!
I didn't want to drill my K31 as its in very good condition so I first bought diopter sights but just couldn't get used to them (I've use scopes on all my guns since childhood).
I then found the BadAce tactical site and ordered their NDT scope mount with picatinny rail and it is absolutely brilliant. Initially, I was a little worried that the scope might not hold accuracy on the rail, but I really had nothing to worry about, loads of rounds down the barrel and still holding a perfect zero.
This piece of kit is easy to install (less than 3 minutes), no need for a gunsmith or an array of tools.
If you own a K31 then the Swiss K31 NDT Scope Mount is a must!
I love it fits perfectly. It was so easy to install with my Nikon pro staff
Very impressed with this scope mount. Fit and finish are great throws the brass without hitting the scope and solid.
I was skeptical that for the price how well this mount would work. Following the video instructions, installation went with out a hitch.
Mounted up on 1932 vintage K31 and went to the range. Used some cheap bullets to get on target at 25 and 100 yards, then went to a proven load for this rifle and WOW. Went from open sights 1.25" on a good day with my 64 year old eyes to sub MOA.
This is a great product. As has been mentioned if you have a K31 get this, Best money I have spent in a very long time.
Hey BAT, make one for the M14
GREAT PRODUCT - HERE ARE INSTALLATION TIPS
This truly is a great NDT scope mount for your Swiss K31 BUT installation may (probably won't be) as easy as they show in their video. Once mounted it works great. The following link takes you to a complete step by step installation:
Easily the best purchase for the K31
Great quality, super simple install. If you're looking for a way to mount your optics to the K31, buy this already. No fuss installation that took no time at all to mount. Thanks to the team at BAT I finally have a solid mounting solution.
Gotta be the best!
At 61 my eyes are the greatest, even as I wear glasses. The side mount was a battle on sight in. This mount is perfect!
As I was sitting in at the range the other day, range members were asking where I got it. I shared the information. Now at next months Military Arms Sihloutte Match we might have more folks with those mounts.

The best solution to a vexing K31 problem
This Mount is not good, not Great it is GREAT!
Goes on in a few minutes. The longest wait is for the locktite to dry. Rock stable and easy to use.
Beautiful, simple design.
Did I say that I really liked it?
If you have a K#! and want a scope, this is the only way to fly.
Now if they could only do one for the K11 and the G11.
