Hi everyone I'm new, my name is Thomas and I have a 10magnium gamo replay, this is my first air rifle, I bought it on the internet, I was told that its power was 45joules while it is only 15, being a 5.5 you understand that it is not very performing, someone can help me with a guide, perhaps telling me where to buy a 220 atm gas piston where it is possible that they ship to Europe, I looked at eBay but for Italy I don't think they ship from the USA. THANKS TO EVERYONE AND I HOPE TO HEAR US SOONIn your country the maximum power output is restricted. If you want full power airrifles in Europa you best buy it in Holland,, then you also avoid additional costs or customs problems. Try krale.shop/nl
