Hi all, I have a krytac trident mk2 spr and was running it stock, I live in Northern Ireland and restricted to 1 joule so I wanted to squeeze more range and accuracy out of my rifle, a couple of people recommend the pre r hoped krytac barrel from umbrella armory and as it was on sale I got it, as far as I can tell there is no difference in range, the bbs either shoot of to the left or right and my fps and joule has dropped from about 0.8 stock to about 0.5/0.6, and 290fps stock to about 255/268 with the r hop barrel all on 0.28g bbs , now as far as I'm aware r hops are ment to improve everything not make it worse, and the barrel came with a hop up with the rhop arm installed, so is there anything I can check or have I just wasted my money. Thanks in advance for your help.
