Sight Hole Repositioning

One change … great advantages!

We moved the sight hole under the gun chuck block (part 41 for DA, BP, AB-HVLP and part 10 for HT).

The advantages?

• the sight hole is in a more protected position than the previous one;
• when the outside of the gun is being washed, this avoids oxidation of the thread by corrosive liquid which would hinder dismantling of the gasket pouch (part 47 for DA, BP and AB-HVLP, and part 48 for HT).
