browning bl-22

I came across a Bl-22 Browning 22 caliber rifle that has a 24", octagon barrel with proper browning marks on it and the receiver looks like a grade 2 type. Appears tp be a recently made gun, not an antique. Can't find any info on it. Anybody know when and how many were made?
Thank you.

Are you quite sure that it‘s a .22?

Browning also made a version called the BL-17, chambered in .17 HM2 (17 Mach 2), and this was available with a 24“ barrel.

I shot a little ammo through it. Definitely a .22.
