Lets get this straight... Charging handles on these types of carriers should be tapped and threaded into the carrier (then welded).
That SKS charging handle looks to be threaded into the carrier - is that correct? I have removable charging handles on other 7.62 rifles and even have installed (probably foolishly) the Tromix large knurled charging handles over several Kalishnikov style rifles, and had a left side NON-reciprocating handle on an AKM from a FAL that was built into the top dust cover.
The removable charging handle (on a SIG) is attached into a slot and held in place by a spring loaded lock. The only reason its removable is for removal of the "AR type" bolt carrier. It is light and secure when locked in place.
The Tromix charging handle cover for AKMs is attached with a huge metal pin that you screw down onto the original handle with a big honking allen wrench and with RED lock-tight. I inspect them every time I shoot the gun(s) and I still don't' trust them not flying off, even though I have never heard of a problem. I am always tempted to take them off.
The non-reciprocating left side FAL handle built into the AKM top cover, is "non-reciprocating" and worked by grabbing the front of the bolt carrier with a tab when pulling the charging handle back. The mechanism rode in a welded track inside the top cover, but stayed forward and actually the handle folded flat during cycling of the action. Never feared for it removing the left side of my face.
I am not trying to be a dick about this, but this is deadly serious shieza! I posted this quote from Dan once before and I will post it again since it does not appear to be remembered:
...If you do purchase one from somewhere, be sure that the handle is screwed into the bolt carrier (not welded to the bolt carrier only). Reason: Bolt carrier welded handles can break-off/detach during shooting and cause injury. How do I know? Dave at Neit Arms (now closed) in Canada had experimented with welded handles and one detached and broke his eye socket. Screwed in handles is a must.
"...broke his eye socket.." thats not something you leave the range from and stop off at McDonalds for a Quarter Pounder on your way to the emergency room to have your head stapled back together.
One final quote from Forest Gump:
