I have a type 56, Chinese stamped SKS that I believe was made between 1966-71(?)  The gun is extremely clean and well maintained, and there are no traces of cosmoline or other lubricants on the bolt assembly or rails.  However, I have noticed that when I return the bolt from the open position back to a closed position that, at times, it will leave a gap of approximately 1 cm.  This only occurs when I assist the bolt back into place, whereas if I am firing or allowing the bolt to slam back after chambering a round it will completely close without an issue.  If anyone could help me understand what I am either doing wrong (ie. not placing the bolt assembly back in line properly), or if this is simply a design aspect, it would be greatly appreciated.  I understand that there are safeguards on the SKS that will keep it from firing out of battery, but I do want the firearm to be in perfect operating condition.  Thanks in advance for any information ya'll can provide.

It doesn't need your assistance.

IOW don't ride the bolt home.

What you describe is normal. The bolt carrier is hanging up on the round in the mag because you aren't letting it slam home. Pull it back and let it go.


ETA: always make sure it's pointed in a safe direction because I saw one go bang once.

+1 on all those.  Let go and let it do what it was designed to do.  Never ride any bolt on any gun or it will be out of battery.

I have two chinese SKS's and both of them exhibit this phenomenon.  Actually about every one I have seen that is fairly new and not worn in will do this.  It is simply the bolt hanging up on the locking lug and not having enough force for the recoil spring to fully overcome the force of friction of the bolt sliding past the locking lug in the receiver.  They do not have to be loaded for this to happen, but it is more common for them to do it if they are loaded.  Don't worry about it. When loading the rifle sipmly let the bolt fly forward under its own power and don't ride the handle and everything will be fine.  I do ride the bolt down when closing an unloaded gun on an empty chamber though to minimize the impact of the carrier with the receiver.
