It just occurred to me, that there are only very few types of cocking handles that can actually be ambidextrous.
Basically, you could have a "pumpgun" style charging, a "lever action" type of charging, a G3/FAL type of charging, a G36 type of charging or an AR type of charging.
The "pumpgun" style of charging would connect a handle below the barrel to the bolt. By pulling the "pump" back, you would pull the bolt back and run the action. The handle would abslutely have to be non-reciprocating, since anything else would make holding the rifle impossible.
The Lever action connects the bolt to a lever near the trigger. The same hand that pulls the trigger must perform the charging action. Again the handle would need to be non reciprocating, or it would rip the shooters fingers off. I have no real experience with lever action guns, so I can't make any comment on pros and cons for this one.
With G3/FAL type f charging I mean a charging handle that is forward of the magazine, and has a handle on the 6 and 9 o'clock position. This has the advantage of being out of the way of the shooter. Such a handle can be reciprocating or not, since the shooter never gets anywhere near it when shooting.
The G36 style is one of my personal favorites. The handle is on top of the bolt, directly mounted onto it. It can be produced reciprocating or not, but because the handle automatically flips back to the inside (or doesn't protrude at all, like in the early version of the AR-15), it doesn't get in the way of the shooter.
This however requires a carrying handle, to protect the handle from accidental charging, and keep things out of the way of the charging handle path.
The AR style is similar to the G36 style, but the handle is mounted behind the main sights block. It must be non reciprocating, since it would otherwise punch the shooter's face every time the gun is fired. It is also hard to cycle the gun while pointing the gun at a target.
Am I missing some method here? Keep in mind I only mean AMBIDEXTROUS methods of charging the gun. Yes, a lefty can switch hands and use the gun the same way a proper human being can, but to keep it simple let's focus on true ambidextrous designs here.
Which charging handle is your favorite? What pros and cons do you see with each design?
