That's exactly why I won't be attempting my 75's
Especially those little gear covers need the right tools and knowledge to do the job properly. I'd make them look like a blind man with boxing gloves on did the rebuild..
I could, given the right tools and a methodical gentle approach have a good go, but id rather it was done properly by a pro.
There's always little do's and don'ts to get the job done properly so the gun shoots as well as it can and lasts the test of time.
Something as simple as correct lubrication or no lubrication at all can make all the difference.
I want to try and do myself justice shooting these target rifles so its important they work as intended or I'm never going to improve the skill of shooting accurately .
I think if I could get my hands on a low value 75 for repair I might be tempted to have a go myself.
The major problem is the breech seal availability or lack there of at the moment.
