Accuracy, quality power, sturdy mounts .
My obsession still remains from then.
Have recently bought a nr mint FWB 124, 11.5 ftlb
I fitted it with a Sportsmatch op adj mount and a Bushnell Legend.
Running on either QYS 9.56 domed or JSB Exact.
Seriously good performance still ,out of a 40+yr old gun.
The 124's are still the business, especially when they were fitted with the 300S barrels...and now ..the really good ammo...wow.
