Strong and lightweight - Midwest Industries AR-15/M16 M-Series Two Piece Drop-In M-LOK Handguard

I got the rifle length rail for my M16A5 project, seeking to improve on the M16A4 I was issued in the Marines. I went with this rail because it's 40% lighter than the KAC quad rail and it didn't require me to remove my fixed front sight post (so I can still fix a bayonet, rah). Some folks like to use a free-float rail, but I don't see this as necessary. I can still hit targets out to 500yds, and the 2-piece drop-in makes installation and cleaning easy.

Fits tight, holds zero for lasers. No complaints.
