Hiya guys. Anyone out there got a good working knowledge of repairs and tuning for this rifle. By tuning I don't mean thrashing it for power, either....
Currently trying to help my uncle with his which is peaking at 9.5ftlb. Its shot thousands of pellets so I'm wondering if its on its way out. Hammer spring has been replace with a new genuine part. No gain. Got a beauty of a barrel on it though. Design is a bit shabby
Any PMs would be greatly appreciated.
