Have Air Arms sorted out the zero shift problem, which plagued the early ones. All the ones ive seen so far at shoots have their shrouds missing and different air strippers fitted. Im thinking of getting one,but i dont want to replace half of it,to get it to keep zero. Anyone know if the latest ones...

You say you have fitted a Tinbum tuning kit,do you mean his spring guides?

If you have used his short stroking kit,then that could be your problem.The MK1 +2 had the ideal stroke to start with.
Its the MK3 that benefits the short stroke tuning kit.
Reducing a Mk 1 by 14mm will nobble your power.

Hi all.
Just looking for ideas for blinging up my Prosports.
So far i have a Matt Winser silencers on them.
Nice engraved leather sling
Rowan brass trigger guard,rowan brass trigger.
Brass safety catch.
Rowan black adjustable butt pad.
MTC Mamba lite scope with shade.

Any more suggestions please!

Just a update on my post.

After a few outings the MK2 sprung gun has dropped in power to 10.7.
The muzzle flip has disapeared now.

I havent opened her to check the spring length as shes shooting nice at 10.7.
Strange goings on regarding the power drops and spring length loses..

Iv just fitted a MK2 Prosport spring in my short stroked 14mm extension,25mm HW sealed MK3 Shes doing 11.4 with no added washers,cocking effort is only a fraction more than when running a Titan No.10. Very quick shot cycle,but just a bit of muzzle flip,which is bothering me. There is no loss of site...

just tried ringing them,but they are closed today.
Are they the importers for them then?

I didnt actually buy the springs from them..
Il try them again tomorrow
Many thanks

I have two Prosports both short stroked with tbt piston extensions 25mm HW seals and Titan XS no.10 springs. They were both set up shooting nicely at 11.5 and have been fine for the last 4 months. Now both of them have lost power dropping to 9ftlbs! Iv stripped them and the only thing i can find tha...

I have a 2009 and a 2015 Prosport.
Both the quality of the internals are fine in mine.
They do benefit from a relube,as the AA lube is a right cacky stuff.

Iv been told the MK2 spring will rub on the piston and not fit????

Im toying with the idea of getting a Bullpup.
What are they like shooting from prone ala HFT style?
