Hi guys this is a question to you guys who know how to tune your pcp's, has i cannot send it to air superiority has i live in the UK, i am trying to get the best out of my rifle that is why i put up a post on how to tune. I had a few replies but know one has really helped me with any explanations on how to tune my rifle correctly on how to tune it to the best of the rifles ability. I hope there is one of you on the forum which can help a new enthusiast. I am a firm believer if you cannot repair or modify something you own yourself dont get into the sport or hobby in the first place. I like computers i didnt know much about them apart from using them but something went wrong with my computer so i researched the problem and fixed it. Since then i have fixed quite a few and also built a couple. I love been able to fix things and modify things myself it bgives you a sense of pride that you have fixed it yourself. I have modded a couple of pcp's now, and this will be my third i am installing a huma reg a depinger and changing the hammer spring i have also modded the barrel port has well has the breach port once i have installed the parts i would like to know if there is anything else i could do to modify the rifle i'e i have heard of polishing the hammer, adjusting the top hat pin in length crowning the barrel and also adjusting the hammer weight. So i would like to know off some of you veteran tuners, what else i could ontop of the new huma reg, depinger and hammer spring exchange to get not only shot to shot consistency, but to get my rifle to the point where i get a 10 shot 1 hole groups at 40 yards or more and i know this can be achieved i just need some advice on hjow to make it so. I hope you guys may help a fellow enthusiast so please leave a comment or pm me thankyou.
