Aero Precision AR-15 15″ ATLAS R-ONE M-LOK Handguard – Anodized Black – BLEM
The Aero Precision ATLAS R-ONE 15″ M-LOK Handguard is built for lightweight AR-15 setups that still demand a rigid, dependable lockup. Machined from 6061-T6 aluminum, the R-ONE keeps a slim profile while providing a full-length top Picatinny rail and M-LOK slots for modern accessory mounting. Aero’s ATLAS Taper Lock system clamps evenly around a dedicated barrel nut to help prevent rail distortion during installation and maintain a secure, repeatable fit.
This is a BLEM item—fully functional, but it may show cosmetic imperfections. No returns are accepted on blemished products.
