MARUI/BOLT techs??

[dannyeprice23]

Just after a bit of advice. 
 

got a BOLT MK18 that ran like a train when new, but after a couple years is feeling a bit ‘tired’ shall we say. Can anyone recommend a decent tech to get in touch with to restore it back to its former glory? Some techs I have spoken to won’t touch the recoils series, others will but unless it’s Marui they don’t want to know.! 
 

any and all help appreciated 

thanks in advance

Are there no bolt techs that feature stuff on YouTube that you could contact ?
