AR15 M16 Quadrail Handguard
The NcStar MAR4L is a rifle-length two-piece quad rail handguard built for AR-15 and M16 platforms with a standard rifle-length gas system. Machined from 6063 aluminum and finished in matte black hardcoat anodizing, it replaces the factory plastic handguards in minutes using the existing delta ring and front sight base — no gunsmithing or special tools required. Four numbered Picatinny rails give you full-length mounting space for optics, lights, lasers, vertical grips, and backup sights. A solid upgrade for shooters who want a true accessory-ready forend on a full-size AR-15 or M16 without the cost or labor of a free-float system.

Perfect for my 20 inch build, no complaintsBeen looking for a rifle length quad rail that wouldnt break the bank for my A4 clone build and this is exactly what I needed. Fit my 20 inch barrel AR with rifle gas system perfectly, literally just popped off the old handguards and dropped this right in. Took maybe 10 minutes and that includes me fumbling with the delta ring lol. The extra length over a carbine rail gives you so much more room to mount stuff, I have a bipod and light on it with plenty of space left over. Really impressed with this for the money.
