Need advice on updated AR handguard

[trbii]

I’m unsure how to measure handguard lengths, does this look like a 8”? It’s an old, heavy, clunky quad rail on a LWRC M6A3 carbine. Thought I had to have a piston action AR 15-20 years ago, surprise, it’s a front heavy design. Was wondering if these new (to me), long, slender M-Lok slotted hand guards would lighten this front end? Somewhat noticeably?

Looks more like 10" to me.
Some handguards will not fit piston uppers. Make sure it is either, compatible or, you'll be able to return it.

A cigarette looks like 8 inches to me...

Oh man, the qd rails are hot again all of the sudden. You should keep them. But I have switched a couple of mine over. Still have the Surefire qd’s though. However, most of the AR accessories I possess are mlok.
Whatever you do, don’t go dickmod pattern.
Oh, for handguard measurements you need to back to where it meets the upper receiver to measure.
