Hi all, looking for a bit of advice, I'm looking to upgrade my krytac trident mk2 spr and crb, so as I live in Northern Ireland we're stuck to 1 joule and I've put a maple leaf bucking and their omega nub in both and truthfully not much if any difference, so I know the stock barrel in both are 6.05mm and that prometheus do barrels for krytac but are they worth it, or do they even make a difference at 1 joule. Thanks in advance for your help and look forward to hearing from you.
