Hello all,
    I have 2 triangle charging handle and need a little help. One is original and the other I bought off a member here a few years back that is a TS (top secret). I believe I know which is which but would like you're all  inputs.

Thanks
Craig

hmmm... very subtle differences, that I can see, kinda odd at the back of the channel near the triangle, and sharp on the gas key end of one.  



What are you thinking?

I agree,

Have a demilled in front of me and the chamfers are the same on the bottom one.

Here are some real ones from de-mils. Right is a 601 I cut that was bent and left is from a early XM16 with a square forge upper.

Now Im going to have to go home and rip all mine out and look at them. Its probably just like the differences in early port doors and machining of early lowers, lots of changes and small differences going on in early parts.

I just checked my 68 SP1 and a later 70's SP1 charging handles and the ends where the gas key goes through are identical to the one that I have, (the one on the right) and the 2 that you have displayed.  Square sided before rounding at the end. Clear as mud???
