Unfortunately not.
The main gripe was the angled attack of the breach which usually leads to the breach seal inconsistantly sealing.
Bowkett considered the barrel too short where they should have dispensed with the plenum chamber idea.....which didnt really work bytheway....and ran the barrel full length.
The grip is somehow not quite right, where switching back to something like a comfy Tempests or 53s grip is a pleasurable return.
I had big consistancy issues with the novel guide rod, ending with me remachining a redesigned one which improved matters considerably but i never conquered the breach issue.
It was possible the best and most well known example of inconsistancy for shooting beautifully, with a run good accuracy and then somehow hitting a patch of inconsistancy and poor accuracy.....which proved annoying.
I eventually gave up chasing its tail as did many shooters but it looked a great gun on paper.
