Perfect upgrade handrail for classic m4 - Magpul Industries MOE Carbine Length AR-15/M4 M-LOK Handguard

I bought this handguard as a replacement for my classic M4 kit I recently acquired from PSA. It's much slimmer and ergonomic than the classic, as well as much more modular which if you're reading this you already knew! Mounting rail pieces to it was simple, although it's important to note that the MLOK on the top won't fit anything except for the 3 space pieces. The sides and bottom can hold any combination of the sizes, but for whatever reason the slots on top aren't as long and don't accommodate the longer pieces because of that.

Installation was the hardest part, but once you get the idea it snaps in to place smoothly and tightly. Overall I'm very pleased with it, and will probably buy more for any future builds!
