The R-ONE from Aero Precision is the latest addition to their Handguard lineup. Made from 6061-T6 Aluminum, the R-ONE Handguard range is engineered to be lightweight and compact, making it an ideal choice for building a lightweight firearm. With Aero Precision's ATLAS attachment system, the handguard mounts securely while still maintaining a slim profile. The ATLAS system includes two tapered locking nuts for more even pressure distribution when clamping. Additionally, a ratcheting detent adds extra security during installation. The R-ONE Handguard is available in both KeyMod and M-LOK® configurations in lengths of 12" and 15", with 7" and 9" versions coming soon. One of the reasons that the R-ONE is lightweight is due to the design of the mounting hardware, which weighs 4.72 oz, the same for all ATLAS Handguard options.
