Walther LGU

[Toby1tyke]

Good evening all,
I'm looking for recommendations for a tune on my LGU.
Firstly the trigger but I suppose any meaningful mods/ tuning which will enhance an already nice gun.
TIA.
Ps, I do not meddle so it would be a hands on tune I want

Hi,
For non-top competetition use YouTube have bought a Top airbus, the trimmer I prefer is the Rowan Engeneering, perfect adjustable.
The most simple solution is buy a longer screw for the frist stage, will give a nice result, bus I prefer the other option.
Best,
HJM

open the port out a tad.. around 3.2mm is a good starting point... 3.4mm probably better...

You can fit the tx trigger blade with a little fettle this sorts the trigger out

I had tested first using HW97 25mm vortek kit , and now I have installed the airrifleheadquarter tune

Is really amazing! better than TX200 tuned, just replacing the spring and with very tight tomhat

How do you open up the port up so precisely to 3.2 or 3.4???

reamers.

I have a taper reamer that goes from 2.5 to 4.5, over a length of 50mm
so that's 2mm dia over 50mm, or 0.04mm dia per length. so a .2mm difference in dia represents 5mm in length (depth), which is pretty noticable. When using this taper, I generally go in from both sides. I also have parallel reamers when I need to be more precise.

I also have a set of 0.1mm increment drill bits from 1.0 to around 5mm - not more more than a tenner on the bay. Bearing in mind they only get used to tickle out existing ports before reaming finish, even with a basic quality they will probaly last decades.
