Prosport cosistancy

[EV2UK]

Hi guys.

I have a factory new Prosport with a build date of December 2016.

Only had it a few weeks and haven't really had a play yet.
I have however tinkered woth the trigger slightly.

Ran it through my Chronograph today and it is very consistent..
The problem is that it is very consistantly around 812-818 with 8.4g. 177.



I did notice that it has 5 washers on the spring guide when I took the trigger block off.
Is it just a case of removing a couple of these.?
I'd like it to run around 11fpe and not the current 12.4 it currently is.


Chronograph assumed to be correct as my EV2 is still being read perfectly.

I would take them all out and re-test. You will then know roughly what each should give you back when reintroduced.

Man, that's some iron willpower there! I usually rip the box open with screwdrivers to save time!

Make sure you keep the washers somewhere safe!
My tx200 started at 13 ft-lb with 8.4 grain aa fields.

I took the washers out and it came down do 11.3 ft-lb. Perfect
After a few thousand shots it settled down to 10.5 ft-lb and stayed there. Unfortunately by this time i had lost the washers and had to get new ones.

I'm no expert but it sounds to me like the air arms springs aren't 'set' from the factory, therefore they need shooting a bit to bed them in.

I'm now planning on selling my tx200......to buy a walnut pro sport! Can't wait
