These are great rifles.
They're fun to shoot, mild recoiling, and are capable of really good accuracy. Couple that with their rarity, and you've got a nice find.
Until you get pix up, here's a few of mine....
With stock disc....and the lovely "custom" sling the seller had on the rifle.
Here's one without stock disc....these are generally the lower serial #'d ones....
Here's an advertisement from when the Madsens were originally imported....
When I took the Madsen with the disc out for a spin a couple of years ago at a public range, I had an interesting encounter. An older gent sighting in a Remington with a scope the size of the Hubble asked how I liked my "Springfield". I told him it was a Madsen, and that I liked it very much. He asked where my scope was. I told him this rifle didn't have a scope and that I was shooting targets with iron sights, as the range was only 100 yds. He seemed incredulous that anyone would shoot at 100 yds without a scope. He "bet" me I wouldn't even hit the target.
I set up my rifle, loaded it with 5 rds of Korean PS75 surplus ammo, and let 5 rds fly. I looked through my spotting scope and chuckled. At the next break, I retrieved my target and showed the gent this group-
He promptly asked at what store he could buy one of those Colombian rifles....
I put it in the case quickly in case I was asked to repeat the grouping...
They will shoot.
