Description

The Leapers MTU045SEM Arwen Handguard is a free-floating AR accessory machined for strength and modularity.

The design provides multiple M-LOK mounting points, a full-length Picatinny rail that aligns flush with the upper receiver, and an ergonomic octagonal profile with lightening cuts. Integral anti-rotation tabs and a patented steel barrel nut simplify installation and maintain alignment under use.
