***SPF***F/S BRNO model 4, .22 LR, Pics will likely give you more info than I know about this little gun, but here it goes. These guns were made by BRNO in Czechoslovakia. These guns are sought after for both shooters adn collectors. I traded for this one a couple of years ago, put a scope that I had in the safe on it and shot it about 50 shots. It shoots the Wolf Match Target ammo at about 1/2" at 50 yrds as I remember. It would do better with a different driver and playing a little with ammo combinations, I would guess. The only things that hurts the collector value is that it does not have the sights that should be on it. On the plus side it doesn't really look like they had ever been installed. Feel free to PM my with questions. $XXX + shipping for gun and rings. Scope is a no longer of rifle. Thanks.
