Tuning Weihrauch HW95 Out-of-the-Box / Vortek HO Tune comparisons

I have also bought an HW95 Luxus Field Pro and out of the box the shot cycle was very harsh and the groupings was bad even after a couple of hundreds of shots, then I completely stripped it, cleaned all the parts, relubed and put everything back together. Now the rifle is very very accurate. Does still have some spring noise, but the accuracy is very good and this gun is very good at longer distances. Just added a top hat bush at the front of the spring side that goes into the piston.
