To All,
Found the problem . I purchased a New Bull Barrel 22 , tried the New Magazines in the Tiger 10 , worked perfectly! the Tiger 10 Mags tried in the New Bull Barrel , and was the same as the Tiger 10, would only index up side down!!!.
The 3 Magazines strangly failed at the same time , dispite stripping , cleaning close inspection , i can not see any problem with them. The new type mags have different index lock levers , the Tiger 10 was not at fault at all. A costly repair and time consuming over 3 Magazines which look normal and work perfectly out of the gun.
I am now the proud ow
