For a couple of years now I have been the owner of a BRNO 21F carbine in caliber 8X57IS. It is completely unaltered and has the knurled receiver ring characteristic of this model. It does not have the integral scope bases found on the 22F model.

Unfortunately, it is equipped only with open sights, and my vision is such that I simply cannot use open sights. However, I am very reluctant to alter this original specimen to fit either receiver sights or scope mounts. Unless I do so, it is merely a museum piece, and I prefer not to own rifles I cannon shoot.

I own another BRNO in this same caliber, a 22H, which does have the integral bases and has now been fitted with a set of Warne rings and an appropriate scope, but it is a rifle, not a carbine.

Any suggestions for a solution to my dilemma, other than donating the carbine to a deserving volunteer?
