Charging handle won't "fit"

[lftd&pwrstrok'n]

The AR-10 charging handle is slightly longer and beefier...if it is the same length as the BCM then you do indeed have an out of spec CH and if the GS is longer then you have a AR10 CH...which is what I'm in need of if you find that it is and want to sell it...thanks

That thing is loooong gone. Worked in his AR15. Apparently the tolerance on the CMMG upper were too tight?
