A.R.M.S. #40; What's the attached wire cable for?

[OH58D]

I have an older A.R.M.S. #40 Standard for for my Colt and just got a new one for my LMT. Attached to the thing is a thin cable/wire which seems to be a retainer of some kind. What is it for?

Regards,

its for the "captive nut" don't worry about it.

It's a retainer for people who can't/won't loctite the BUIS on. So when the BUIS falls off, you won't lose all of the little parts you need to put it back on.
