Thats what I'm refering to. "Proper upgrades". I'm no bolt action sniper by any means, never have been. Spring will always be more consistent than gas. I'm not here to get into a sniper pissing contest, just saying that what I do know of spring sniper rifles is that some parts don't work that well with some brands of rifles. Research is the key to build a reliable rifle.
