3CR Tactical AR-15 Free-Float Quad Rail Handguard — 4-Sided Rail

$27.99

Free-float quad rail handguard for the AR-15. Mounts through a barrel-nut system that carries all load off the barrel and gas block, so bipod pressure, sling tension, and mounted lights or lasers don't flex the barrel and shift point of impact. Picatinny rail runs the full length on all four sides — top, bottom, and both sides — so you can position optics, backup irons, lights, foregrips, and QD sling swivels anywhere along the tube.

Build:

  • T6 aluminum body, black anodized finish
  • Four-sided Picatinny (MIL-STD 1913) rail, 20mm spec
  • Free-float design — no barrel or gas-block contact
  • Barrel-nut mount system, wrench and set screw included
  • Fits standard AR-15 upper receivers

Fit notes: Free-float handguards must match your barrel length and gas-system length. Confirm the handguard clears your gas block before installation — a low-profile gas block is usually required to fit inside a free-float tube. If you run an A2 front sight base or a full-height clamp-on block, this handguard will not clear.

Torque the barrel nut to spec, index the top rail to your upper receiver rail, and verify the gas tube runs clean through the barrel-nut bore before final assembly. See our AR-15 handguard install notes for the full procedure.
