Beeman RS Series...Help..

[drumdrumman]

So just about to strip my RS-2 Series Duel Barrel..Not been done since New.. Do I just get new seals e.t.c and Re-Lube or is it worth fitting a Gas Ram as mine has a lot of Twang..
Do you think this will fit ? proteksupplies.co.uk/misc-parts.html

I believe the guns for the UK Market have been Restricted but dont know how..
The Air gun spares places in the US wont post to the UK so just have to go with parts I can get over here..

Sorry for all the questions guys and Gals....
