Recently spotted a BRNO Mod2 .22 in our Ads paper, came c/w scope 4x40 & Moderator.
A Farmer had it but never used it during the past years, FA Dept suggested he get rid off it.
£100 later it's home with me.
I didn't think the mod' was up to much, no noise reduction at all, but I googled the brand and it was rated (a Parker-Hale). I had decided to replace it but left it on the rifle to protect the threads, 30 rounds later and it is working perfectly
What could have been wrong with the mod' in the first instance?
