If you are looking for a lightweight AR-15 handguard but don’t want to sacrifice strength, then check out the Sons of Liberty Gun Works EXO3 rail. This 9.5” free float handguard features M-LOK attachment slots down the sides and bottom and has angled slots for attaching offset lights. It also has a full length picatinny top rail that indexes with M4 flat top upper receivers to ensure it is flush and won’t rotate over time. It locks to the upper receiver with an aluminum barrel nut and steel hardware. This M-LOK handguard is made from 6061-T6 aluminum and has a type III hardcoat anodized finish for long term wear and corrosion resistance. At 9.5”, this rail will cover most carbine length gas systems with low-profile gas blocks.
