Im looking for a gas tube for a yugo sks the one that I have leaks gas and the gun won't cycle does anyone know where I can find one for a reasonable price?
If the o-ring fix worked temporarily, the paperclip fix would have worked too. It does the same thing...creates a better seal betweent the tube and the gas valve.
You have two options.
1) Replace the gas tube (link to original provided earlier)
Often times the gas valve is the part that is erroded due to years of use (and abuse) with corrosive ammunition, and / or not being cleaned regularly when used as a military service rifle. The gas tube may be in bad shape too, so check each one.
Many a Yugo SKS that doesn't cycle properly, but does with the paper clip or o-ring fix has been fixed with the gas valve.
Its up to you in how you want to fix your Yugo SKS, but sometimes the valve does the trick and is a bit cheaper too.
